                               PROSPECTUS SUMMARY
 
     Group 1 Automotive, Inc. was formed in December 1995 to acquire automobile
dealerships and related operations and has conducted no operations to date.
Immediately prior to the closing of the offering made hereby (the "Offering"),
Group 1 Automotive, Inc. will acquire, in separate simultaneous transactions
(collectively, the "Acquisitions") in exchange for $5.4 million and 9,074,914
shares of its Common Stock, par value $.01 per share ("Common Stock"), 13
corporations (each a "Founding Company" and, collectively, the "Founding
Companies") that own automobile dealerships and related operations that are
currently part of four separate dealership groups (the "Founding Groups"). The
Offering is conditioned on the consummation of the Acquisitions. Unless
otherwise indicated, all references to "Group 1 Automotive" herein mean Group 1
Automotive, Inc. prior to consummation of the Acquisitions, and all references
to the "Combined Company" and the "Company" herein mean Group 1 Automotive,
Inc., as consolidated with the Founding Groups following consummation of the
Acquisitions. See "The Acquisitions".
 
     The following summary is qualified in its entirety by the more detailed
information and financial statements, including the notes thereto, appearing
elsewhere in this Prospectus. Unless otherwise indicated, all share, per share
and financial information set forth herein (i) have been adjusted retroactively
to give effect to (a) the Acquisitions and (b) a 900-for-one split of the
outstanding shares of Common Stock of Group 1 Automotive effected on December
13, 1996, and (ii) assume no exercise of the Underwriters' over-allotment
option. See "Underwriting". Investors should carefully consider the information
set forth in "Risk Factors".
 
                              THE COMBINED COMPANY
 
     Group 1 Automotive was founded to become a leading operator and
consolidator in the highly fragmented automotive retailing industry. Upon
consummation of the Acquisitions, the Combined Company will own 30 automobile
dealership franchises ("dealerships") and five collision service centers located
in Texas and Oklahoma that sell new and used cars and light trucks, provide
maintenance and repair services, sell replacement parts and provide related
financing, insurance and service contracts. The Combined Company will represent
21 American and Asian brands including Acura, Chevrolet, Chrysler, Dodge, Eagle,
GMC, Honda, Isuzu, Jeep, Kia, Lexus, Lincoln, Mazda, Mercury, Mitsubishi,
Nissan, Oldsmobile, Plymouth, Pontiac, Suzuki and Toyota. The Combined Company's
dealerships will include the second largest Toyota dealership in the United
States as measured by 1996 new retail unit sales and one of the largest
dealership groups in Oklahoma. The Founding Groups sold an aggregate of 38,000
new and used retail units in 1996, which represented .11% of the number of new
and used retail units sold by franchised dealers in the United States in 1996.
 
     The principals of the Founding Groups have over 90 years of combined
experience in the automotive retailing industry with family ownership dating
back as far as 1917. In addition, the principals of the Founding Groups have
been recognized as leaders in the automotive retailing industry, serving at
various times in leadership positions in state and national industry
organizations. The Founding Groups' dealerships have also received numerous
awards based on various performance measures. The principals of the Founding
Groups will continue to manage their businesses and play a significant role in
the Combined Company's operating and acquisition strategies.
 
     Group 1 Automotive believes that the Combined Company's structural,
managerial and operational strengths will include (i) brand and geographic
diversity; (ii) the ability to capitalize on regional economies of scale; (iii)
cost savings derived from nationally centralized financing and administrative
functions; (iv) the experience of the Combined Company's senior management in
successfully consolidating and operating in highly fragmented industries; (v)
the reputations, experience and performance of the Founding Groups' management
and principals as leaders in the automotive retailing industry; (vi) the
established customer base and local name recognition of the Founding Groups'
dealerships; (vii) the Founding Groups' proven ability to source high quality
used vehicles cost-effectively through trade-ins and off-lease programs; and
(viii) access to equity incentives to attract and retain high quality personnel.
                                        3
<PAGE>   4
 
     The Combined Company will pursue a growth strategy led by a management team
with extensive experience in consolidation and the management of growth
companies. B.B. Hollingsworth, Jr., Chairman of the Board, President and Chief
Executive Officer of the Combined Company, has experience not only in the
automotive retailing industry, but also in consolidating a major national
industry, having served in various senior management capacities, including
President, of Service Corporation International during its early growth period
as the world's leading consolidator of the funeral industry. In addition, John
T. Turner, Senior Vice President -- Corporate Development, has been actively
involved in the acquisition efforts of Service Corporation International,
serving under Mr. Hollingsworth as Senior Vice President -- Corporate
Development and serving more recently as Managing Director -- Corporate
Development, Europe. See "Management".
 
     The U.S. automotive retailing industry is estimated to have annual sales in
excess of $600 billion, with the 100 largest dealer groups generating less than
10% of total sales revenue and controlling approximately 5% of the 22,000
existing franchised dealership locations (representing approximately 53,000
dealerships). It is estimated that sales by franchised automobile dealers
account for one-fifth of the nation's total retail sales of all products and
merchandise. Group 1 Automotive believes that the enormous size and the
fragmentation of the industry, together with increasing capital costs of
operating automobile dealerships, lack of a viable exit strategy (especially for
larger dealerships) and the aging of dealership owners provide an attractive
environment for the Combined Company's consolidation opportunities. In addition,
many successful and entrepreneurial "megadealers" have expressed interest in
expanding their operations, but have been restrained by a lack of capital. Group
1 Automotive believes that the Combined Company will provide an attractive
opportunity for these megadealers due to the Combined Company's formation by a
consolidation of similar megadealers, its access to the public capital markets,
and its position as a vehicle for growth.
 
BUSINESS STRATEGY
 
     Group 1 Automotive plans to achieve its goal of becoming a leading
consolidator, while maintaining its high operating standards in the automotive
retailing industry, by (i) enhancing growth through acquisitions and (ii)
implementing an operating strategy that focuses on decentralized dealership
operations, nationally centralized administrative functions, the expansion of
higher margin businesses, a commitment to customer service and the
implementation of new technology initiatives. By complementing the Founding
Group's industry leaders, management talent and proven operating capabilities
with a corporate management team which is experienced in achieving and managing
long-term growth in a consolidation environment, Group 1 Automotive believes
that the Combined Company will be in a strong position to execute this strategy.
 
     GROWTH THROUGH ACQUISITIONS
 
     Group 1 Automotive intends to implement an aggressive, yet disciplined,
acquisition program by pursuing (i) large, profitable and well managed
"platform" acquisitions in large metropolitan and high-growth suburban
geographic markets that the Founding Groups do not currently serve and (ii)
smaller "add-on" acquisitions that will allow the Combined Company to increase
brand diversity, capitalize on regional economies of scale and offer a greater
breadth of products and services in each of the markets in which it operates. In
this regard, Group 1 Automotive has negotiated and executed an arrangement
letter with Chase Securities Inc. and Comerica Bank for a $125 million credit
facility (the "Credit Facility"), of which a portion will be used, in
combination with the Combined Company's common stock, for acquisitions. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Combined Founding Groups' Commitments -- Credit Facility".
 
     ENTERING NEW GEOGRAPHIC MARKETS. Group 1 Automotive intends to expand into
geographic markets it does not currently serve by acquiring large, profitable
and well established megadealers ("platforms") that, like the Founding Groups,
are leaders in their regional markets. The Combined Company will target new
platform megadealers having superior operational and financial management
personnel which the Combined Company will seek to retain. Group 1 Automotive
believes that the
                                        4
<PAGE>   5
 
retention of existing high quality management will enable acquired megadealers
to continue to operate effectively with management personnel who understand the
local market, while allowing the Combined Company to source future acquisitions
more effectively and expand its operations without having to employ and train
untested new personnel. Moreover, Group 1 Automotive believes that the Combined
Company will be well positioned to pursue larger, well established acquisition
candidates as a result of its depth of management, the Combined Company's
capital structure and the reputation of the principals of the Founding Groups as
leaders in the automotive retailing industry.
 
     EXPANDING WITHIN EXISTING MARKETS. Group 1 Automotive plans to acquire
additional dealerships in each of the markets in which it operates ("add-ons"),
including acquisitions that increase the brands, products or services offered in
that market. Group 1 Automotive believes that these acquisitions will facilitate
the Combined Company's operating efficiencies and cost savings on a regional
level in areas such as facility and personnel utilization, vendor consolidation
and advertising. Group 1 Automotive has recently entered into definitive
agreements to acquire, subject to manufacturer approval and a due diligence
investigation, two dealership locations consisting of Acura, Buick, Dodge, Ford,
Mercedes-Benz, Nissan and Volvo dealerships in Texas for aggregate payments of
$9.0 million in cash. These two acquisitions, if consummated, would also require
the Combined Company to incur approximately $13.0 million of floorplan
indebtedness in connection with the purchase of vehicle inventories of the
dealerships.
 
     MANUFACTURERS' LIMITATIONS ON ACQUISITIONS. The Combined Company's
acquisition program may be limited to some extent by the Manufacturers (as
defined herein). Under the limitations currently imposed by the Manufacturers,
the Combined Company could acquire no more than five additional Toyota
dealerships, two additional Lexus dealerships, four additional Honda
dealerships, one additional Acura dealership, approximately 400 additional Ford
and Lincoln Mercury dealerships and 10 additional GM dealership locations
(within the next two years, subject to being increased). The Combined Company,
upon consummation of the Acquisitions, will own two Toyota, one Lexus, three
Honda, two Acura, one Lincoln and one Mercury franchise and three GM dealership
locations. The other Manufacturers, which have no such limitations, accounted
for the following approximate number of dealerships in the United States, as of
December 31, 1996: Chrysler Corporation, 13,000 (at 4,600 locations); Nissan,
1,200; Mitsubishi, 500; Isuzu, 500; Suzuki, 300; and Kia, 200. However, not all
of these existing dealership locations and franchises may be eligible for
acquisition. In addition, all of the Manufacturers, whether or not they have
numerical limitations on the number of dealerships that may be acquired, will
require the Combined Company to obtain the consent of the applicable
Manufacturer prior to the acquisition of any dealership franchises of such
Manufacturer, and may withhold such consents based on other considerations, such
as the failure of existing dealerships to comply with their franchise agreements
or to meet required CSI scores, or the ownership by the Combined Company of
dealerships of competing Manufacturers. Also, as a condition to granting its
consent to the transfer of the three Honda and two Acura dealerships to be
acquired by Group 1 Automotive pursuant to the Acquisitions, American Honda has
imposed additional restrictions on the Combined Company, including a requirement
that more than 50% of the outstanding Common Stock of the Combined Company be
owned at all times by persons approved by American Honda, restrictions on
transfers of the shares of Common Stock acquired by the stockholders of the
Founding Companies pursuant to the Acquisitions, and the requirement that
American Honda approve the ownership by any stockholder of 5% or more of the
Common Stock of the Combined Company (other than certain institutional
investors, which may own up to 10%), as well as any future public offering of
Common Stock of the Combined Company. All of the foregoing could have the effect
of limiting the Combined Company's ability to implement its acquisition program.
In addition, American Honda's policy on public ownership of Honda and Acura
dealerships requires that individuals or entities that acquire, own or control
more than 5% of the Common Stock of the Combined Company must provide American
Honda with copies of all filings made to the Securities and Exchange Commission,
all comparable filings made to state agencies and annual audited financial
statements. See "Risk Factors -- Manufacturers' Control over Dealerships", "Risk
Factors -- Restrictions Imposed by Agreement with American Honda Motor Co.,
Inc.", "Risk Factors -- Risks Relating to Failure to Meet Manufacturer CSI
                                        5
<PAGE>   6
 
Scores" and "Risk Factors -- Dependence on Acquisitions for Growth;
Manufacturers' Restrictions on Acquisitions".
 
     Of the approximately 15 million new vehicles sold in the United States in
1996, approximately 31.3% were manufactured by General Motors Corporation
("GM"), 25.4% were manufactured by Ford Motor Company, 16.2% were manufactured
by Chrysler Corporation, 7.7% were manufactured by Toyota Motor Corp., 5.6% were
manufactured by Honda Motor Co., Ltd, 5.0% were manufactured by Nissan Motor
Co., Ltd and 8.8% were manufactured by other manufacturers.
 
     OPERATING STRATEGY
 
     Group 1 Automotive intends to implement an operating strategy that focuses
on decentralized dealership operations, nationally centralized administrative
functions, expansion of higher margin businesses, commitment to customer service
and new technology initiatives.
 
     Group 1 Automotive has formed an operations committee comprised of the
chief operating officers of the Founding Groups and the general managers of the
dealerships in order to identify and share best practices. Group 1 Automotive
intends to incorporate the key officers and management of the Combined Company's
future acquisitions into this operations committee. Group 1 Automotive believes
that this operations committee will promote the widespread application of the
Combined Company's broad strategic initiatives, facilitate the integration of
the Founding Groups and future acquisitions and improve operating efficiency and
overall customer satisfaction.
 
     DECENTRALIZED DEALERSHIP OPERATIONS. Group 1 Automotive believes that
decentralizing the Combined Company's dealership operations on a regional, or
platform, basis will enable it to provide superior customer service and a
focused, market-specific responsiveness to sales, service, marketing and
inventory control. Local presence and an in-depth knowledge of customers' needs
and preferences are important in generating internally-driven market share
growth. By coordinating certain operations on a platform basis, Group 1
Automotive believes that the Combined Company will achieve cost savings in such
areas as vendor consolidation, facility and personnel utilization and
advertising. Group 1 Automotive intends to create incentives for the Combined
Company's entrepreneurial management teams and sales forces at the regional
level through the use of stock options and/or cash bonus programs.
 
     NATIONALLY CENTRALIZED ADMINISTRATIVE FUNCTIONS. The consolidation of
purchasing power on a centralized basis in the area of financing should result
in significant cost savings. For example, in connection with the Offering, all
of the Combined Company's floorplan financing will benefit from interest rate
reductions. Rate reductions have already become effective with respect to
approximately 75% of the Founding Groups' floorplan debt. The current reductions
range between 25 and 225 basis points. Additionally, the Combined Company's
Credit Facility, once closed, will result in further rate reductions. Subsequent
to the Offering, the Combined Company intends to refinance approximately $50
million in floorplan financing with the Credit Facility. The impact of these
changes is expected to reduce the Combined Company's annual interest expense by
more than $1.0 million. Furthermore, Group 1 Automotive expects that significant
cost savings can be achieved through the consolidation of administrative
functions such as risk management, employee benefits and employee training. For
example, Group 1 Automotive has negotiated insurance coverage that is expected
to result in annual cost savings to the Combined Company of approximately 25 to
30 percent.
 
     EXPAND HIGHER MARGIN ACTIVITIES. The Combined Company will focus on
expanding higher margin businesses such as used vehicle retail sales, service
and parts and finance and insurance. While each of the Combined Company's
platforms will be able to operate independently in a manner consistent with its
specific market's characteristics, each platform will pursue an integrated
strategy to grow each of these higher margin businesses to enhance profitability
and stimulate internal growth. With a competitive advantage in sourcing, the
ability to provide manufacturer-backed extended service contracts, and
attractive lease financing, new vehicle franchises are especially well
positioned to capitalize on industry growth in used vehicle sales. In addition,
each of the Combined Company's dealerships will offer an integrated service and
parts department, which will provide an important source of recurring higher
                                        6
<PAGE>   7
 
margin revenues. The Combined Company also will have the opportunity on each new
or used vehicle sold to generate incremental revenues from the sale of extended
service contracts, credit insurance policies and finance and lease contracts.
Each of these business areas will be a focus of internal growth.
 
FOUNDING GROUPS
 
     The Combined Company will be formed by a consolidation of the businesses of
the following previously separate dealership groups:
 
     HOWARD GROUP. This group is one of the largest dealership groups in
Oklahoma, consisting of Acura, Chevrolet, Chrysler, Dodge, Eagle, GMC, Honda,
Isuzu, Jeep, Mazda, Plymouth, Pontiac and Toyota dealerships located in Oklahoma
City (the "Howard Group"). Additionally, the Howard Group has entered into an
agreement to purchase a Chevrolet dealership in Tulsa, Oklahoma for the
assumption of all of its liabilities, which are currently approximately $2.5
million. See "The Acquisitions". Robert E. Howard II, the principal owner, has
been involved in the automotive retailing industry for over 28 years. In 1996,
the Howard Group sold 8,181 new vehicles. From 1994 to 1996, the Howard Group's
revenues increased by $54.7 million, or 24.1%, to $282.0 million from $227.3
million. During this period, gross profit increased $9.3 million, or 32.9%, to
$37.6 million from $28.3 million.
 
     MCCALL GROUP. This group consists of the second largest Toyota dealership
in the United States, as ranked by 1996 new retail unit sales, and a Lexus
dealership, both located in Houston, Texas (the "McCall Group"). Sterling B.
McCall, Jr., the principal owner, has been involved in the automotive retailing
industry for more than 27 years, having been granted the first stand-alone
exclusive Toyota dealership in Houston. In 1996, the McCall Group sold 6,458 new
vehicles. From 1994 to 1996, the McCall Group's revenues increased by $111.2
million, or 62.7%, to $288.5 million from $177.3 million. During this period,

Honda, GMC, Oldsmobile, Mitsubishi, Lincoln, Mercury and Kia dealerships in
Beaumont, Texas, a Nissan dealership in Richardson, Texas (a suburb of Dallas)
and two Nissan dealerships, one Mitsubishi dealership and one Suzuki dealership
in the Austin, Texas area (the "Smith Group"). The Smith family has been in the
automotive retailing business since 1917. In 1996, the Smith Group sold 5,983
new vehicles. From 1994 to 1996, the Smith Group's revenues increased by $1.2
million, or 0.6%, to $218.3 million from $217.1 million. During this period,
gross profit increased $1.9 million, or 7.0%, to $29.1 million from $27.2
million.
 
     KINGWOOD GROUP. This group consists of one Honda and one Isuzu dealership
in Kingwood, Texas, a suburb of Houston (the "Kingwood Group"). The Honda
dealership was established in 1989 and the Isuzu dealership was established in
1996. Mr. Hollingsworth, and John H. Duncan, a director of the Combined Company,
own interests in these dealerships. In 1996, the Kingwood Group sold 756 new
vehicles. From 1994 to 1996, the Kingwood Group's revenues increased by $4.9
million, or 15.8%, to $35.9 million from $31.0 million. During this period,
gross profit increased $1.5 million, or 39.5%, to $5.3 million from $3.8
million.

(1) The value of the shares of Common Stock issued in connection with the
    Acquisitions (other than the Common Stock to be sold by the Selling
    Stockholder) was discounted by 35% from the initial public offering price of
    $12.00 to give effect to the two year lock-up that each stockholder of the
    Founding Companies entered into in connection with the Acquisitions. This
    discount was based on an independent valuation study as to the impact of the
    restrictions on the value of the Common Stock.
 
(2) Includes 592,303 shares of Common Stock issued to Mr. Howard in the
    Acquisitions and placed in escrow pursuant to the terms described below.
 
     Bob Howard Automotive-East, Inc. ("Bob Howard East"), a corporation wholly
owned by Mr. Howard, has entered into an agreement to purchase a Chevrolet
dealership in Tulsa, Oklahoma (the "Tulsa Dealership") for approximately $2.5
million. This purchase price was funded by a $2.5 million loan, bearing interest
at the prime rate plus 100 basis points, from Mr. Howard to Bob Howard East. GM
has denied its approval of Bob Howard East's acquisition of the Tulsa Dealership
due to the Howard Group's failure to meet GM's required CSI score levels. The
Combined Company, through Howard Pontiac-GMC, Inc. ("Bob Howard Automall"), one
of the Founding Companies, has entered into an agreement to purchase Bob Howard
East for the assumption of all Bob Howard East's liabilities, which consist of
the $2.5 million loan from Mr. Howard to Bob Howard East. These acquisitions
will be consummated immediately upon GM's approval of such acquisitions.
 
     When the Founding Groups allocated the shares of Common Stock to be
received by each Founding Group in the Acquisitions, it was anticipated that the
acquisition of the Tulsa Dealership would be consummated prior to consummation
of the Acquisitions. Mr. Howard was to receive 592,303 shares of Common Stock in
the Acquisitions as consideration for the Tulsa Dealership. These shares will be
held in escrow pending the acquisition of the Tulsa Dealership.
 
     Upon consummation of Bob Howard East's acquisition of the Tulsa Dealership
and the Combined Company's acquisition of Bob Howard East, the escrowed shares
will be released to Mr. Howard. In this event, the consideration to be paid to
Mr. Howard for the Tulsa Dealership will be (i) the 592,303 shares of Common
Stock (having a value of approximately $4.6 million, which will be profit to Mr.
Howard, based on the initial offering price of $12.00 per share discounted by
35%) and (ii) the assumption of Bob Howard East's $2.5 million liability to Mr.
Howard. This consideration will be paid to Mr. Howard by the Combined Company
(through Bob Howard Automall).
 
     If these two acquisitions are not consummated with GM's approval within two
years of the Offering: (i) the Combined Company will not acquire the Tulsa
Dealership, (ii) Bob Howard East's $2.5 million liability to Mr. Howard will not
be assumed by the Combined Company, (iii) Bob Howard East will retain the right
to acquire the Tulsa Dealership and (iv) rather than being distributed solely to
Mr. Howard, the escrowed shares will be distributed pro rata to the stockholders
of the Founding Companies. This pro rata distribution will be allocated as
follows: the McCall Group, 161,913 shares; the Smith Group, 190,340 shares; the
Howard Group, 207,940 shares; and the Kingwood Group, 32,110 shares. If the
                                        8
<PAGE>   9
 
Combined Company does not acquire the Tulsa Dealership and the escrowed shares
are distributed pro rata, the Combined Company will recognize additional
goodwill of approximately $3.0 million.
 
     The escrowed shares will remain outstanding regardless of whether the
acquisition of the Tulsa Dealership is consummated, and the Combined Company
will receive no additional consideration or assets if such shares are
distributed pro rata as described above. If the Combined Company's acquisition
of the Tulsa Dealership is not consummated, the fair value of the Howard Group's
contribution to the Combined Company will decrease and the fair value of the
Smith Group's, McCall Group's and Kingwood Group's contributions to the Combined
Company will remain the same. The treatment of the escrowed shares and the terms
and conditions upon which such shares are to be released were the subject of
arms-length negotiations among the Founding Groups. The Board of Directors of
Group 1 Automotive believes that the potential pro rata distribution of the
escrowed shares to the stockholders of the Founding Companies is a fair
reallocation of the fixed number of shares of Common Stock to be issued to the
Founding Groups in the Acquisitions, based upon the increased relative
contribution of the McCall, Smith and Kingwood Groups and the decreased relative
contribution of the Howard Group.
 
     See "Risk Factors -- Risks Relating to Failure to Meet Manufacturer CSI
Scores".
 
     The consideration to be paid by Group 1 Automotive for each of the Founding
Companies was determined by negotiations among the principals of the Founding
Companies as to the relative value of each of the Founding Companies. As such,
no one individual determined the consideration to be paid in connection with the
Acquisitions. Group 1 Automotive and the Founding Companies did not use an
independent third party to determine the relative values of each of the Founding
Companies but agreed among themselves on the values attributable to each of the
Founding Companies based on an evaluation of each of the Founding Companies'
operating results and prospects for growth. At the time of the execution of the
Stock Purchase Agreements in connection with the Acquisitions, Messrs.
Hollingsworth, Howard, McCall and Smith were, in addition to stockholders of
certain of the Founding Companies, directors of Group 1 Automotive. In addition,
at the time of execution of such Stock Purchase Agreement, Mr. Hollingsworth,
was the sole stockholder of Group 1 Automotive. As a result, Messrs.
Hollingsworth, Howard, McCall and Smith might be considered to have a conflict
of interest with respect to the Acquisitions. The only steps taken to resolve
any such conflicts was ratification of all of the Stock Purchase Agreements by
all members of the Board of Directors of Group 1 Automotive.
 
                   CONSIDERATION RECEIVED BY RELATED PARTIES
 
     In connection with the Acquisitions, the following directors, officers and
stockholders owning more than 5% of the Common Stock together with their spouses
and affiliates will receive shares of Common Stock as follows: Mr.
Hollingsworth -- 196,368 shares of Common Stock (excluding the 350,000 shares of
Common Stock that Mr. Hollingsworth currently owns); Mr. Howard -- 2,956,955
shares of Common Stock; Mr. McCall -- 1,461,031 shares of Common Stock; Mr.
Smith -- 679,181 shares of Common Stock; Mr. Duncan -- 196,368 shares of Common
Stock; Mr. Whalen -- 774,040 shares of Common Stock. In addition, Mr. Howard
will receive $2.3 million in cash in the Acquisitions.
 
     The following directors, officers and 5% stockholders together with their
affiliates have guaranteed, as of June 30, 1997, aggregate indebtedness of
certain of the Founding Companies as follows: Mr. Hollingsworth -- $2.7 million;
Mr. Howard -- $37.8 million; Mr. McCall -- $30.6 million; Mr. Smith -- $5.2
million; Mr. Duncan -- $2.7 million. In connection with the Acquisitions, the
Combined Company will take all commercially reasonable efforts to obtain the
release of guarantees by certain of the Founding Company stockholders of certain
secured debt of the Founding Companies.
 
     Directors, officers and 5% stockholders, or affiliates of such persons, who
have incurred indebtedness that is secured by guarantees of certain Founding
Companies and the amounts of such indebtedness, as of June 30, 1997, are as
follows: Mr. Howard, approximately $7.8 million; Mr. McCall and affiliates,
approximately $8.0 million; and Mr. Smith and affiliates, approximately $4.6
million. With the exception of the Round Rock guarantee described below, all
applicable lenders have agreed to release
                                        9
<PAGE>   10
 
such guarantees upon consummation of the Offering. One of the Founding Companies
(Round Rock Nissan) will continue to guarantee approximately $2.4 million of
indebtedness of SKLR Round Rock, L.C., a limited liability company in which Mr.
Smith owns a 22% interest. If such guarantee is not released within 90 days of
consummation of the Acquisitions, the Combined Company will have the option to
acquire certain property securing such indebtedness. See "Certain
Transactions -- Loans".
 
     In connection with the Acquisitions, all related party receivables and
payables are being settled. Such transactions will result in a net payment of
$19,720, as of June 30, 1997, by the McCall Group to Mr. McCall. Additionally,
as part of the Acquisitions, certain of the Founding Companies will distribute
pre-acquisition S corporation accumulated adjustment accounts to their
stockholders. Such distributions will result in the payment of approximately
$97,104 to Mr. Hollingsworth, $3.4 million to Mr. Howard, $337,500 to Mr. Smith
and $97,104 to Mr. Duncan.
 
     Certain of the properties leased by the Founding Companies are owned by
officers, directors or 5% stockholders of the Combined Company or their
affiliates. As part of the Acquisitions, the Founding Companies will replace
each of these related party leases (with the exception of one related party
lease described in "Certain Transactions -- Leases") with a standard lease
agreement. The rent on each of these properties will initially be the same as
the rent on the properties prior to consummation of the Acquisitions subject to
adjustment every five years based on the Consumer Price Index. For a detailed
description of these leases, see "Certain Transactions -- Leases".
 
     Messrs. McCall and Whalen own 18% and 11%, respectively, of Dealer
Solutions, L.L.C. ("DSL"), which will provide management information systems,
software and related services to certain dealerships of the Combined Company and
receives certain fees in connection therewith. For a detailed description of the
agreement between DSL and the Combined Company, see "Certain
Transactions -- Other".
 
     Upon the completion of the Offering, options to purchase 325,000 shares of
Common Stock at the initial public offering price will be granted to officers
and directors of the Combined Company as compensation for future services to be
rendered to the Combined Company as follows: Mr. Hollingsworth -- 100,000; Mr.
Turner -- 125,000; Mr. Thompson -- 80,000; Mr. Duncan -- 10,000 and Mr. Bidwell
- -- 10,000.

(1) Group 1 Automotive anticipates, for the Combined Company, increases in
    revenues and decreases in cost of sales and selling, general and
    administrative expenses. The owners of the Founding Groups currently have
    agreements in place which decrease the fees and commissions paid to the
    dealerships for sales of certain finance and insurance products and increase
    the cost of certain aftermarket products. Upon completion of the
    Acquisitions, such agreements will be terminated and the dealerships will
    recognize an immediate increase in revenues and decrease in cost of sales.
    Additionally, certain employees and owners of the Founding Groups have
    agreed to reductions in compensation that will result in a decrease in
    selling, general and administrative expenses upon completion of the
    Acquisitions. The items above are not reflected in the financial data
    presented and would have resulted in an increase in income from operations
    of the combined Founding Groups of approximately $4.3 million in 1995, $5.0
    million in 1996 and $2.1 million for the six months ended June 30, 1997.

                                    RISK FACTORS
 
     Prospective purchasers should carefully consider the following factors, as
well as the other information and financial data contained in this Prospectus,
before purchasing the shares of Common Stock offered hereby.
 
ABSENCE OF COMBINED OPERATING HISTORY
 
     Group 1 Automotive, which was incorporated in December 1995, has conducted
no operations to date other than in connection with the Acquisitions and the
Offering. The Founding Groups have been operated and managed as separate
independent entities to date, and the Combined Company's future operating
results will depend in part on its ability to integrate the operations of these
businesses and manage the combined enterprise. The management group that will
lead the Combined Company has been assembled only recently, and there can be no
assurance that the management group will be able to effectively and profitably
integrate the Founding Groups and any future acquisitions, or to effectively
manage the combined entity. The inability of the Combined Company to do so could
have a material adverse effect on the Combined Company's business, financial
condition and results of operations.
 
MANUFACTURERS' CONTROL OVER DEALERSHIPS
 
     Each of the Founding Groups' dealerships sells automobiles pursuant to
franchise agreements with automobile manufacturers or authorized distributors of
the manufacturers. The term "Manufacturers" as used herein means Ford Motor
Company ("Ford Motor"), General Motors Corporation ("GM"), Toyota Motor Corp.
and its United States affiliate, Toyota Motor Sales, U.S.A., Inc. (collectively,
"Toyota Motor"), Honda Motor Co., Ltd. ("Honda Motor") and its United States
affiliate, American Honda Motor Co., Inc. ("American Honda"), Nissan Motor Co.,
Ltd. ("Nissan Motor") and its United States affiliate, Nissan Motor North
America, Inc., ("Nissan North America"), Chrysler Corporation, Mitsubishi Motor
Sales of America, Inc., ("Mitsubishi Motor"), American Isuzu Motors, Inc.
("American Isuzu"), American Suzuki Motor Corporation and Kia Motors America,
Inc., but does not include Mazda Motor of America, Inc. since the sole Mazda
franchise owned by the Howard Group, which operated at an immaterial loss for
the year ended December 31, 1996 and the six months ended June 30, 1997, is in
the process of being sold. Through the terms and conditions of these franchise
agreements, Manufacturers will exert considerable influence over the operations
of the Combined Company's dealerships. Each of the franchise agreements includes
provisions for the termination or non-renewal of the manufacturer-dealer
relationship for a variety of causes including any unapproved change of
ownership or management and other material breaches of the franchise agreement.
Prior approval of the relevant manufacturers is required with respect to
acquisitions of automobile dealerships, and a manufacturer may deny the Combined
Company's application to make an acquisition or seek to impose further
restrictions on the Combined Company as a condition to granting approval of an
acquisition. See "-- Dependence on Acquisitions for Growth; Manufacturers'
Restrictions on Acquisitions" and "-- Restrictions Imposed by Agreement with
American Honda Motor Co., Inc.". Certain state laws, however, limit the ability
of automobile manufacturers to reject proposed transfers of dealerships,
notwithstanding the terms of any dealer or franchise agreement. See
"Business -- Franchise Agreements". The loss of one or more of the Combined
Company's franchise agreements could have a material adverse effect on the
Combined Company's business, financial condition and results of operations.
 
     As a condition to granting their consent to the Acquisitions, American
Honda, GM, Toyota Motor, Nissan North America, American Isuzu, Ford Motor and
Mitsubishi will impose restrictions on the Combined Company. These restrictions
include restrictions on (i) the acquisition of more than a specified percentage
of the Common Stock (5% in the case of American Honda; 20% in the case of GM,
Toyota Motor, Nissan North America and American Isuzu, and 50% in the case of
Ford Motor and Mitsubishi Motor) by any one person who in the opinion of the
Manufacturer is unqualified to own a dealership of such Manufacturer or has
interests incompatible with the Manufacturer, (ii) certain material changes in
the Combined Company or extraordinary corporate transactions such as a merger or
sale of a material amount of assets; (iii) the removal of a dealership general
manager without the consent of the
 
                                       15
<PAGE>   16
 
Manufacturer; (iv) the use of dealership facilities to sell or service new
vehicles of other Manufacturers; (v) in the case of GM, the advertising or
marketing of non-GM operations with GM operations; (vi) in the case of Ford
Motor, mandatory binding arbitration of any dispute between the Combined Company
and Ford Motor concerning Ford Motors franchise agreements; (vii) in the case of
Nissan Motor, the decrease in Mr. Smith's ownership of Common Stock to below
169,750 shares at any time during the five-year period following the Combined
Company's execution of the new Nissan Motor franchise agreement; (viii) in the
case of GM and Mitsubishi, any change in control of the Combined Company's Board
of Directors; and (ix) in the case of Ford Motor, any change in the Combined
Company's Board of Directors or management. These restrictions are in addition
to the restrictions discussed under "-- Dependence on Acquisitions for Growth;
Manufacturers' Restrictions on Acquisitions" and "-- Restrictions Imposed by
Agreement With American Honda Motor Co. Inc.". If the Combined Company is unable
to comply with these restrictions, the Manufacturer may require the Combined
Company to (i) sell the assets of the dealerships to the Manufacturer or to a
third party acceptable to the Manufacturer, and/or (ii) terminate the dealership
agreements with the Manufacturer.
 
     Certain of the Manufacturers require the Combined Company to appoint an
employee of the Combined Company (typically designated as the "Executive
Manager") to act as the primary contact between the Combined Company and the
applicable Manufacturer. Such individual typically is required to have
operational control of all of the applicable Manufacturer's dealerships and to
have full authority to resolve issues raised by the applicable Manufacturer in
connection with the operation of the dealership. The Combined Company is not
allowed to change the Executive Manager without the consent of the applicable
Manufacturer. The agreements with the Manufacturers also generally provide for
periodic reporting and notice provisions as a means of determining whether the
Combined Company is in compliance with the restrictions contained in those
agreements. A Manufacturer, upon its determination of a violation of the
restrictions, will notify the Combined Company of the violation and the Combined
Company will generally have a period to cure the violation. If the Combined
Company disputes the Manufacturer's claim of a violation or is unwilling or
unable to cure the violation, the Manufacturer may enforce the remedies
specified in the agreement through judicial or regulatory proceedings or in
certain instances through arbitration.
 
DEPENDENCE ON ACQUISITIONS FOR GROWTH; MANUFACTURERS' RESTRICTIONS ON
ACQUISITIONS
 
     Growth in the Combined Company's revenues and earnings will depend
significantly on the Combined Company's ability to acquire and consolidate
profitable dealerships. There can be no assurance that the Combined Company will
be able to identify, acquire or profitably manage and integrate additional
dealerships, if any, into the Combined Company, or that it will be able to do so
without substantial costs, delays or other operational or financial problems. In
addition, increased competition for acquisition candidates may develop, which
could result in fewer acquisition opportunities available to the Combined
Company and/or higher acquisition prices. Further, acquisitions involve a number
of special risks, including possible adverse effects on the Combined Company's
operating results, diversion of resources and management's attention, inability
to retain key acquired personnel, risks associated with unanticipated events or
liabilities and amortization of acquired intangible assets, some or all of which
could have a material adverse effect on the Combined Company's business,
financial condition and results of operations. Finally, the ability of the
Combined Company to grow through acquisitions could be significantly affected by
the price of the Common Stock since the Combined Company intends to grow
substantially through the issuance of its Common Stock in acquisitions. Any
substantial decline in the price of the Common Stock could, therefore, have a
material adverse effect on the Combined Company's growth strategy.
 
     The Combined Company will be required to obtain the consent of the
applicable Manufacturer prior to the acquisition of any dealership franchises.
Obtaining the consent of the Manufacturers for acquisitions of dealerships could
take a significant amount of time. Obtaining the approvals of the Manufacturers
for the Acquisitions has taken almost one year. Although Group 1 Automotive
believes that subsequent acquisitions by the Combined Company will take
significantly less time since Group 1
 
                                       16
<PAGE>   17
 
Automotive has current completed applications and/or agreements with all
Manufacturers, there can be no assurance that future approvals will not involve
delays. The Manufacturers have not advised Group 1 Automotive that approvals for
subsequent acquisitions will take significantly less time, and, if the Combined
Company experiences delays in obtaining, or fails to obtain, approvals of the
Manufacturers for acquisitions of dealerships, the Combined Company's growth
strategy could be materially adversely affected. In determining whether to
approve an acquisition, the Manufacturers may consider many factors, including
the moral character, business experience, financial condition, ownership
structure and CSI scores of the Combined Company. In addition, Manufacturers may
limit the number of such Manufacturers' dealerships that may be owned by the
Combined Company or the number that may be owned in a particular geographic
area.
 
     Toyota Motor currently limits the number of dealerships which may be owned
by any one group to seven Toyota and three Lexus dealerships nationally and
restricts the number of dealerships that may be owned to (i) the greater of one
dealership, or 20% of the Toyota dealer count in a "Metro" market (multiple
Toyota dealership markets as defined by Toyota Motor), (ii) the lesser of five
dealerships or 5% of the Toyota dealerships in any Toyota region (currently 12
geographic regions), and (iii) two Lexus dealerships in any one of the four
Lexus geographic areas. Toyota Motor further requires that at least nine months
elapse between acquisitions of Toyota or Lexus dealerships. Similarly, it is
currently the policy of American Honda to restrict any company from holding more
than seven Honda or more than three Acura franchises nationally and to restrict
the number of franchises to (i) one Honda dealership in a "Metro" market (a
metropolitan market represented by two or more Honda dealers) with two to 10
Honda dealership points, (ii) two Honda dealerships in a Metro market with 11 to
20 Honda dealership points, (iii) three Honda dealerships in a Metro market with
21 or more Honda dealership points, (iv) no more than 4% of the Honda
dealerships in any one of the 10 Honda geographic zones, (v) one Acura
dealership in a Metro market (a metropolitan market with two or more Acura
dealership points), and (vi) two Acura dealerships in any one of the six Acura
geographic zones. Toyota Motor and American Honda also prohibit ownership of
contiguous dealerships and the dualing of a franchise with any other brand
without their consent. Because the Combined Company intends to pursue "platform"
acquisitions in large metropolitan markets that the Founding Groups do not
currently serve, as well as "add-on" acquisitions that will increase brand
diversity, the Combined Company's acquisition program will not be dependent on
its ability to acquire multiple dealerships of any one Manufacturer in any given
Metro market. Therefore, Group 1 Automotive does not believe that the foregoing
restrictions on ownership of contiguous dealers impose significant limitations
on its acquisition program.
 
     Ford Motor currently limits the number of dealerships to the greater of (a)
15 Ford and 15 Lincoln Mercury dealerships, or (b) the number of dealerships
with total retail sales of new vehicles in the immediately preceding calendar
year that would equal not more than 5% of total Ford and Lincoln Mercury
vehicles sold at retail in the United States during that year, which number for
each of Ford and Lincoln Mercury dealerships treated separately may not exceed
(a) one Ford dealership in those market areas as defined by Ford Motor from time
to time by Ford Motor for its dealership network having two or less authorized
Ford dealerships in them, or (b) 33 1/3% of the dealerships in any market area,
as defined from time to time by Ford Motor for its dealership network, having
more than three authorized Ford dealerships in them (estimated by the Company to
be approximately 400 dealerships assuming that each Ford and Lincoln Mercury
dealership in the United States had the same revenues). GM has limited the
number of GM dealerships that the Combined Company may acquire during the next
two years to 10 additional GM dealership locations (any one dealership, however,
may include a number of different GM franchises, such as a combination of GMC,
Pontiac and Buick franchises). In addition, GM limits the maximum number of GM
dealerships that the Combined Company may acquire to 50% of the GM dealerships,
by franchise line, in a GM-defined geographic market area (currently
approximately 10,000 dealerships). However, Group 1 Automotive's current
agreement with GM does not include Saturn dealerships and the Combined Company's
future acquisition of a Saturn dealership will be subject to GM approval on a
case-by-case basis. The Founding Groups currently own two Toyota, one Lexus,
three Honda, two Acura, one Lincoln and one Mercury franchise and three GM
dealership locations.

RESTRICTIONS IMPOSED BY AGREEMENT WITH AMERICAN HONDA MOTOR CO., INC.
 
     On October 15, 1997, American Honda filed a complaint under the Texas Motor
Vehicle Commission Code objecting to the proposed transfer of the two Honda and
one Acura dealerships located in Texas to be acquired by Group 1 Automotive
pursuant to the Acquisitions, and seeking, among other things, a statutory stay
of the proposed transfers pending a full and final hearing on the matter. On
October 21, 1997, Group 1 Automotive entered into an agreement with American
Honda (the "Honda Agreement"), on the basis of which American Honda and Group 1
Automotive have filed a joint motion to dismiss the complaint and American Honda
has consented to the transfers pursuant to the Acquisitions. Pursuant to the
Honda Agreement, Group 1 Automotive has agreed to abide by the terms of American
Honda's dealer agreements and to be bound by the terms of American Honda's
policy on public ownership of Honda and Acura dealerships, including the
numerical limitations on dealerships, the restrictions on ownership of
contiguous dealerships and other restrictions, in each case, as described above
under "-- Manufacturers' Control Over Dealerships" and "-- Dependence on
Acquisitions for Growth; Manufacturers' Restrictions on Acquisitions". Pursuant
to such restrictions, the Combined Company is prohibited from owning more than
seven Honda or more than three Acura franchises nationally, and may not own more
than (i) one Honda dealership in a Metro market with two to 10 Honda dealership
points; (ii) two Honda dealerships in a Metro market with 11 to 20 Honda
dealership points; (iii) three Honda dealerships in a Metro market with 21 or
more Honda dealership points; (iv) 4% of the Honda dealerships in any one of the
10 Honda geographic zones; (v) one Acura dealership in a Metro market with two
or more Acura dealership points, or (vi) two Acura dealerships in any one of the
six Acura geographic zones. In addition, the Combined Company has agreed that
neither it nor any of its affiliates will acquire any interest in a Honda or
Acura dealership (other than those currently owned by the Founding Groups)
without American Honda's prior written approval, which shall be at American
Honda's sole discretion.
 
     The Honda Agreement also requires that 50% of the outstanding Common Stock
of the Combined Company be owned at all times by persons approved by American
Honda. Because the Combined Company intends to finance future acquisitions by
issuing shares of Common Stock as full or partial consideration for acquired
dealerships, such restriction could have the effect of limiting the Combined
Company's ability to implement its acquisition program. The Honda Agreement also
requires American Honda's approval prior to any future public offering of Common
Stock of the Combined Company, and provides that American Honda shall have the
right to approve the acquisition of more than 5% of the Common Stock of the
Combined Company by any individual or entity, and any subsequent acquisition of
more than 10%, if such acquisition is reasonably deemed to be detrimental to the
interests of American Honda. The Honda Agreement provides that any such
acquisition may be reasonably deemed to be detrimental to the interests of
American Honda if the acquiring entity (a) competes with American Honda or its
parent, subsidiaries or affiliates in the manufacturing, marketing or selling of
automobile products or services, or owns a substantial economic interest in an
entity that so competes (not including any dealership that sells products of a
competing manufacturer); (b) has criminal affiliations or a criminal record; (c)
has inadequate experience in the automotive sales and service business; (d) has
an unacceptable credit rating; (e) has unacceptable CSI scores; or (f) has had
prior unsatisfactory relationships with American Honda. An institutional
investor may acquire up to 10% of the Common Stock of the Combined Company
without the consent of American Honda, unless such institutional investor (a) is
owned or controlled by or has a substantial economic interest in an entity that
competes with American Honda; (b) has criminal affiliations or a criminal
record; or (c) has acquired, or has a reasonable likelihood of acquiring a
controlling interest in the Combined Company. The Combined Company will be
required to notify American Honda with respect to any such acquisition or
proposed acquisition, and if American Honda does not approve of such
acquisition, the Combined Company will be required to use its best efforts to
prevent such acquisition or, if such acquisition has already occurred, to
reacquire the shares so transferred. The inability of the Combined Company to
prevent such acquisition or to reacquire the shares will be deemed to be a
material breach of the Honda Agreement. In addition, pursuant to the Honda
Agreement, each stockholder of the Founding Companies has agreed not to sell,
transfer or in any manner encumber any of the shares of Common Stock of the
Combined Company acquired by them pursuant to the Acquisitions, or enter into
any agreement or other arrangement
 
                                       18
<PAGE>   19
 
providing for the voting of such shares of Common Stock, without the prior
written approval of American Honda. In the event of any transfer of shares of
Common Stock in violation of such restriction, the Combined Company will be
required to inform American Honda, and if American Honda does not approve such
transfer, the inability of the Combined Company either to reacquire the shares
or arrange for the retransfer of such shares to a person approved by American
Honda will be deemed to be a material breach of the Honda Agreement. The Honda
Agreement also provides that, in the event a controlling interest in the
Combined Company or any subsidiary of the Combined Company that owns any Honda
and Acura dealerships is acquired or threatened to be acquired by an entity not
approved by American Honda, American Honda will be entitled to claim material
breach of the Honda Agreement and exercise its rights upon the occurrence
thereof. In addition, American Honda's policy on public ownership of Honda and
Acura dealerships requires that individuals or entities that acquire, own or
control more than 5% of the Common Stock of the Combined Company must provide
American Honda with copies of all filings made to the Securities and Exchange
Commission, all comparable filings made to state agencies and annual audited
financial statements.
 
     The Honda Agreement provides that any material breach by the Combined
Company will entitle American Honda to require the Combined Company to sell to
American Honda or its designated assignee all of the assets of the Honda and
Acura dealerships then owned or controlled by the Combined Company at their then
current "fair market value". Upon any such sale, the applicable Honda and Acura
dealership agreements will be terminated. Any dispute as to whether a material
breach of the Honda Agreement has occurred, or as to the fair market value of
the Honda and Acura dealership assets, will be resolved by binding, unappealable
and unreviewable arbitration. There can be no assurance as to the amount or
value of the consideration that the Combined Company would receive if American
Honda were to require such a sale and termination of the Honda and Acura
dealerships, and any such sale and termination could have a material adverse
effect on the Combined Company's financial position and results of operations.
The pro forma revenues and income before income taxes of the Combined Company
for the six months ended June 30, 1997 were approximately $450.3 million and
$9.0 million, respectively, of which Honda and Acura dealerships accounted for
approximately $63.0 million and $1.3 million, respectively. The pro forma
revenues and income before income taxes of the Combined Company for the year
ended December 31, 1996 were approximately $825.6 million and $15.4 million,
respectively, of which such Honda and Acura dealerships accounted for
approximately $123.3 million and $3.3 million. See Note 2 to the Pro Forma
Financial Information included elsewhere in this Prospectus.
 
     The Honda Agreement also provides that American Honda or its designated
assignee will have a right of first refusal with respect to any proposed
transfer or sale by the Combined Company of a Honda or Acura dealership's assets
or capital stock. The Combined Company is required to present American Honda
with any bona fide written agreement executed by it with respect to any such
transfer or sale, and American Honda will have 180 days from receipt of such
agreement and such other documents as American Honda shall request to exercise
such right of first refusal, which will enable American Honda (or its designated
assignee) to assume the rights and obligations of the buyer thereunder. If
American Honda determines that such proposed transfer is not bona fide or in
good faith, American Honda shall have the option to purchase the principal
assets of the Combined Company that utilize the Honda and Acura dealership
business, including real estate and leasehold interests, and to cancel the Honda
Agreement and the rights granted thereunder, at a purchase price determined by
good faith negotiations between the parties. In the event that no such agreement
on price can be reached, the purchase price will be exclusively determined in
accordance with unappealable and unreviewable arbitration. The Combined Company
has agreed to indemnify American Honda in respect of any liabilities incurred by
American Honda as a result of the exercise of American Honda's rights of first
refusal or right to purchase the Honda and Acura dealerships upon a material
breach of the Honda Agreement, including liabilities resulting from any claims
brought by potential buyers of the Honda and Acura dealerships.
 
     If the Combined Company determines that it is unable to comply with the
restrictions imposed by the Honda Agreement, or that it will be unable to
implement its acquisition program while subject to the provisions thereof, the
Combined Company may decide to sell the Honda and Acura dealerships and
 
                                       19
<PAGE>   20
 
terminate the Honda Agreement. The agreement with Honda remains in effect only
so long as the Combined Company continues to own Honda or Acura dealerships. Any
such proposed sale to a third party would be subject to American Honda's right
of first refusal. As a result, the Combined Company could be required to wait
for a period of up to 180 days prior to consummating any such sale. In addition,
there can be no assurance as to the value of the consideration that would be
received by the Combined Company in connection with any such sale of the Honda
and Acura dealerships, whether to a third party or to American Honda pursuant to
its right of first refusal, upon a material breach of the Honda Agreement or
otherwise. As of June 30, 1997, the Combined Company had pro forma combined
total assets of approximately $210.4 million and current assets of approximately
$152.1 million, of which approximately $20.9 million and $19.4 million,
respectively, were attributable to Honda and Acura dealerships. The Combined
Company had pro forma combined total liabilities of approximately $162.9 million
and current liabilities of approximately $152.7 million, of which approximately
$18.3 million and $17.9 million, respectively, were attributable to Honda and
Acura dealerships.
 
RISKS RELATING TO FAILURE TO MEET MANUFACTURER CSI SCORES
 
     Many manufacturers attempt to measure customers' satisfaction with
automobile dealerships through systems generally known as the customer
satisfaction index ("CSI"). These manufacturers may use a dealership's CSI
scores as a factor in evaluating applications for additional dealership
acquisitions and participation by a dealership in incentive programs. Certain of
the Founding Groups' dealerships have had difficulty from time to time meeting
their Manufacturers' CSI standards. The components of the various manufacturer
CSI scores have been modified from time to time in the past, and there is no
assurance that such components will not be further modified or replaced by
different systems in the future. The Founding Groups' dealerships' CSI scores in
the past have not had a material adverse effect on these dealerships. However,
the CSI scores of the Howard Group's GM dealerships are currently below GM
levels as required under the GM publication Policies for Changes in GM
Dealership Ownership/Management ("GM Policies"), and as a result, the
acquisition of a Chevrolet dealership in Tulsa, Oklahoma by Bob Howard East, an
affiliate of Mr. Howard has been denied by GM. See "The Acquisitions". Under the
GM Policies each GM dealership must maintain CSI scores that are at or above its
respective zone/branch average for the overall dealership purchase/delivery
category and the overall dealership service visit category. Exceptions will be
considered if (i) the score in each category is no lower than 0.2 points below
the applicable zone/branch average or 0.12 points below national divisional 12
month averages; and (ii) a business plan for the dealership is provided to
improve CSI results in the categories to zone/branch average within two years;
and/or (iii) a positive sustaining trend has been displayed in the dealership's
CSI results in the categories. The scores for the Howard Group's GMC, Pontiac
and Chevrolet dealerships for the purchase/delivery category for the twelve
months ended April 1997 were 3.13, 3.09 and 3.18, respectively, while the
respective zone average were 3.45, 3.43 and 3.44. The scores for the Howard
Group's GMC, Pontiac and Chevrolet dealerships for the service category for the
twelve months ended April 1997 were 2.71, 2.58 and 2.92, respectively, while the
respective zone averages were 3.09, 3.11 and 3.19. The scores for the Howard
Group's GMC, Pontiac and Chevrolet dealerships for the purchase/delivery
category for the three months ended June 1997 were 3.31, 3.33 and 3.18,
respectively, while the respective zone averages were 3.47, 3.42 and 3.44. The
scores for the Howard Group's GMC, Pontiac and Chevrolet dealerships for the
service category for the three months ended June 1997 were 2.84, 2.66 and 3.05,
respectively, while the respective zone averages were 3.12, 3.13 and 3.23. GM
will not permit the Howard Group to acquire the Chevrolet dealership in Tulsa,
Oklahoma until the CSI scores attain the required level, which could occur any
time in the future. If, however, GM does not approve the acquisition of such
dealership within two years after the completion of the Acquisitions the
Combined Company will not acquire the Tulsa Dealership. See "The Acquisitions".
If such CSI scores fail to reach required levels, the Combined Company's ability
to acquire GM dealerships could be adversely affected. Moreover, failure of the
Combined Company's dealerships to comply with the CSI standards of GM as well as
other Manufacturers at any given time in the future could adversely affect the
growth strategy of the Combined Company.
 
                                       20
<PAGE>   21
 
DEPENDENCE ON AUTOMOBILE MANUFACTURERS
 
     The success of each of the Combined Company's dealerships will be highly
dependent upon the overall success of the line of vehicles that each dealership
sells. New vehicles manufactured by Toyota Motor, GM, Honda Motor, Nissan Motor,
and Chrysler Corporation accounted for approximately 34%, 17%, 16%, 14% and 9%,
respectively, of the Founding Groups' new vehicle unit sales for 1996. No other
Manufacturer accounted for more than 3% of new vehicle retail unit sales of
Founding Groups during 1996.
 
     The Combined Company's business will be affected to varying degrees by the
demand for its Manufacturers' vehicles, and by the financial condition,
management, marketing, production and distribution capabilities of such
Manufacturers. In addition, the timing, structure and amount of Manufacturer
sales incentives and rebates will impact the timing and profitability of the
Combined Company's sales transactions and such incentives and rebates change
frequently based on decisions of the Manufacturers. Events such as labor
disputes and other production disruptions that may adversely affect a
Manufacturer may also adversely affect the Combined Company. Similarly, the
delivery of vehicles from Manufacturers later than scheduled, which may occur
particularly during periods of new product introductions, can lead to reduced
sales during such periods. Moreover, any event that causes adverse publicity
involving such Manufacturers may have an adverse effect on the Combined Company
regardless of whether such event involves any of the Combined Company's
dealerships.
 
     The Combined Company will also depend on its Manufacturers to provide it
with a desirable mix of new vehicles. The most popular vehicles generally
produce the highest profit margins and are frequently the most difficult to
obtain from the Manufacturers. If the Combined Company is unable to obtain
sufficient quantities of the most popular models its profitability may be
adversely affected. In some instances, in order to obtain additional allocations
of these vehicles, the Combined Company may elect to purchase a larger number of
less desirable models than it would otherwise purchase. Sales of less desirable
models may result in lower profit margins than sales of the more popular
vehicles.
 
     The Combined Company's franchise agreements with its Manufacturers will not
give the Combined Company the exclusive right to sell a Manufacturer's product
within a given geographic area. Accordingly, a Manufacturer could grant another
dealer a franchise to start a new dealership in proximity to one or more of the
Combined Company's locations or an existing dealer could move its dealership to
a location which would compete directly with the Combined Company, although
certain state laws provide a mechanism for challenging such action in advance
through administrative or legal proceedings. If the Combined Company cannot
prevent a Manufacturer from granting a new franchise near to one of the Combined
Company's dealerships, such grant could have a material adverse effect on the
Combined Company and its operations.
 
RISKS RELATED TO ACQUISITION FINANCING; FUTURE CAPITAL REQUIREMENTS
 
     Group 1 Automotive currently intends to finance the Combined Company's
future acquisitions by issuing shares of Common Stock as full or partial
consideration for acquired dealerships. The extent to which the Combined Company
will be able or willing to issue Common Stock for acquisitions will depend on
the market value of the Common Stock from time to time and the willingness of
potential acquisition candidates to accept Common Stock as part of the
consideration for the sale of their businesses. Since the Combined Company will
focus initially on large "platform" acquisitions, it is possible that the
Combined Company will issue a significant number of additional shares of Common
Stock in connection with such acquisitions in the near future. Such additional
shares of Common Stock could be as much as, or more than, the number of
outstanding shares of Common Stock after giving effect to the Offering. To the
extent that the Combined Company is unable or unwilling to do so, the Combined
Company may be required to use available cash or other sources of debt or equity
financings. Group 1 Automotive has negotiated and executed an arrangement letter
for a bank credit facility with Chase Securities, Inc and Comerica Bank. The
Credit Facility will provide the Combined Company with a secured revolving line
of credit of up to $125 million which may be used for general corporate
purposes, acquisitions, capital
 
                                       21
<PAGE>   22
 
expenditures, working capital and floor plan financing. Group 1 Automotive
currently expects that the net proceeds from the Offering, other existing
resources and the Credit Facility will be sufficient to fund the Combined
Company's acquisition program and other cash needs for at least the next 12
months. However, no assurance can be given that the net proceeds from the
Offering, other existing resources and the Credit Facility will be sufficient to
fund the Combined Company's acquisition program and other cash needs, or that
the Combined Company will be able to obtain adequate additional capital from
other sources. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations -- Combined Founding Groups' Commitments -- Credit
Facility".
 
RELIANCE ON KEY PERSONNEL
 
     The Combined Company will depend to a large extent upon the abilities and
continued efforts of its executive officers and the senior management of the
Founding Groups, including B. B. Hollingsworth, Jr., Robert E. Howard, II,
Sterling B. McCall, Jr., Charles M. Smith, John T. Turner and Scott L. Thompson.
Furthermore, the Combined Company will likely be dependent on the senior
management of any businesses acquired in the future. If any of these persons
becomes unavailable to continue in such capacity, or if the Combined Company is
unable to attract and retain other qualified employees, the Combined Company's
business or prospects could be adversely affected. Although the Combined Company
will enter into an employment agreement with each of its executive officers,
there can be no assurance that any individual will continue in his present
capacity with the Combined Company for any particular period of time. The
Combined Company currently does not have key man insurance for any of its
officers and senior management. See "Management".
 
SUBSTANTIAL COMPETITION
 
     The automotive retailing industry is highly competitive with respect to
price, service, location and selection. The Combined Company will compete with
automobile dealerships (including public franchised dealership consolidators),
private market buyers and sellers of used vehicles, used vehicle dealerships,
service center chains and independent service and repair shops. In the new
vehicle area, the Combined Company will compete with other franchised dealers.
The Combined Company will not have any cost advantage in purchasing new vehicles
from the Manufacturers, and typically will rely on advertising, merchandising,
sales expertise, service reputation and location of its dealerships to sell new
vehicles. In recent years, the Founding Groups have also faced competition from
non-traditional sources such as companies that sell automobiles on the Internet,
automobile rental agencies, independent leasing companies, used-car
"superstores" and price clubs associated with established consumer agencies such
as the American Automobile Association, some of which use non-traditional sales
techniques such as one-price shopping. In addition, Ford Motor has announced
that it is exploring the possibility of going into business with some of its
dealers to create automotive superstores in selected markets. Some of these
recent market entrants may have greater financial, marketing and personnel
resources than the Combined Company, and/or lower overhead or sales costs. In
the parts and service area, the Combined Company also will compete with a number
of regional or national chains which offer selected parts and services at prices
that may be lower than the Combined Company's prices. In addition, there can be
no assurance that the Combined Company's strategy will be more effective than
the strategies of its competitors.
 
CYCLICALITY
 
     Sales of motor vehicles, particularly new vehicles, historically have been
subject to substantial cyclical variation. Group 1 Automotive believes that the
industry is affected by many factors, including general economic conditions,
consumer confidence, the level of personal discretionary spending, interest
rates and credit availability. There can be no assurance that the industry will
not experience sustained periods of decline in vehicle sales, particularly new
vehicle sales, in the future. Any such decline could have a material adverse
effect on the Combined Company.
 
                                       22
<PAGE>   23
 
SEASONALITY
 
     The automobile industry is subject to seasonal variations in revenues.
Demand for automobiles is generally lower during the winter months than in other
seasons, particularly in regions of the United States associated with harsh
winters. Accordingly, Group 1 Automotive expects the Combined Company's revenues
and operating results generally to be lower in its first and fourth quarters
than in its second and third quarters.
 
IMPORTED PRODUCTS
 
     A significant portion of the Combined Company's new vehicle business will
involve the sale of vehicles, parts or vehicles composed of parts that are
manufactured outside the United States. As a result, the Combined Company's
operations will be subject to customary risks of importing merchandise,
including fluctuations in the value of currencies, import duties, exchange
controls, trade restrictions, work stoppages and general political and economic
conditions in foreign countries. The United States or the countries from which
the Combined Company's products are imported may, from time to time, impose new
quotas, duties, tariffs or other restrictions, or adjust presently prevailing
quotas, duties or tariffs, which could affect the Combined Company's operations
and its ability to purchase imported vehicles and/or parts.
 
GOVERNMENTAL REGULATIONS AND ENVIRONMENTAL MATTERS
 
     The Combined Company will be subject to a wide range of federal, state and
local laws and regulations, such as local licensing requirements, consumer
protection laws and environmental requirements governing, among other things,
discharges to the air and water, the storage of petroleum substances and
chemicals, the handling and disposal of wastes, and the remediation of
contamination arising from spills and releases. The violation of these laws and
regulations could result in civil and criminal penalties being levied against
the Combined Company or in a cease and desist order against operations that are
not in compliance. Future acquisitions by the Combined Company may also be
subject to governmental regulation, including antitrust reviews. Group 1
Automotive believes that the Founding Groups substantially comply with all
applicable laws and regulations relating to its business, but future laws and
regulations may be more stringent and require the Combined Company to incur
significant additional costs. See "Business -- Governmental Regulations" and
"Business -- Environmental Matters".
 
ANTI-TAKEOVER EFFECTS OF STOCKHOLDER RIGHTS PLAN AND THE COMBINED COMPANY'S
CHARTER AND BYLAWS
 
     Group 1 Automotive has adopted a stockholder rights plan. This plan and
certain provisions of Group 1 Automotive's Certificate of Incorporation, as
amended ("Charter"), and Bylaws ("Bylaws") may have the effect of discouraging,
delaying or preventing a change in control of Group 1 Automotive or unsolicited
acquisition proposals that a stockholder might consider favorable. These include
provisions providing for a Board of Directors with staggered, three-year terms,
permitting the removal of a director from office only for cause, allowing only
the Board of Directors to set the number of directors, requiring super-majority
or class voting to effect certain amendments to the Charter and Bylaws, limiting
the persons who may call special stockholders' meetings, limiting stockholder
action by written consent and establishing advance notice requirements for
nominations for election to the Board of Directors or for proposing matters that
can be acted upon at stockholders' meetings. The Delaware General Corporation
Law requires super-majority voting thresholds to approve certain "business
combinations" between interested stockholders and Group 1 Automotive which may
render more difficult or tend to discourage attempts to acquire the Combined
Company. In addition, Group 1 Automotive's Board of Directors has the authority
to issue shares of preferred stock ("Preferred Stock") in one or more series and
to fix the rights and preferences of the shares of any such series without
stockholder approval. Any series of Preferred Stock is likely to be senior to
the Common Stock with respect to dividends, liquidation rights and, possibly,
voting rights. The ability to issue Preferred Stock could also have the effect
of discouraging
 
                                       23
<PAGE>   24
 
unsolicited acquisition proposals, thus affecting the market price of the Common
Stock and preventing stockholders from obtaining any premium offered by the
potential buyer. In addition, certain of the Combined Company's dealer
agreements will prohibit the acquisition of more than a specified percentage of
the Common Stock (5% (10% for institutional investors) in the case of American
Honda, 20% in the case of GM, Toyota Motor, Nissan North America and American
Isuzu and 50% in the case of Ford Motor and Mitsubishi Motor) without the
consent of the relevant Manufacturers. See "Management -- Executive Officers and
Directors", "Principal and Selling Stockholders" and "Description of Capital
Stock".
 
POTENTIAL EFFECT OF SHARES ELIGIBLE FOR FUTURE SALE ON PRICE OF COMMON STOCK
 
     Sales of substantial amounts of Common Stock in the public market
subsequent to the Offering could adversely affect the market price of the Common
Stock. Upon consummation of the Acquisitions and the Offering, the Combined
Company will have 13,953,050 shares of Common Stock outstanding (14,673,050
shares if the Underwriters' overallotment option is exercised in full). Of these
shares, the 4,800,000 shares of Common Stock offered hereby (5,520,000 shares if
the Underwriters' overallotment option is exercised in full) will be freely
tradable without restriction or further registration under the Securities Act of
1933, as amended (the "Securities Act"), except for shares held by persons
deemed to be "affiliates" of the Combined Company or acting as "underwriters" as
those terms are defined in the Securities Act. The remaining 9,153,050 shares of
Common Stock outstanding will be "restricted securities" within the meaning of
Rule 144 under the Securities Act and will be eligible for resale subject to the
volume, manner of sale, holding period and other limitations of Rule 144.
Currently, 565,000 shares of Common Stock are issuable under existing stock
options granted to certain executive officers and employees of Group 1
Automotive. Options exercisable for 661,700 shares of Common Stock will be
granted to directors and employees under Group 1 Automotive's 1996 Stock
Incentive Plan prior to completion of the Offering. An additional 773,300 shares
of Common Stock are reserved for issuance to employees and directors of the
Combined Company under Group 1 Automotive's 1996 Stock Incentive Plan. In
addition, 200,000 shares of Common Stock are reserved for issuance to employees
of the Combined Company under the 1998 Employee Stock Purchase Plan. See
"Management -- 1996 Stock Incentive Plan", "Management -- 1998 Employee Stock
Purchase Plan", "Description of Capital Stock" and "Shares Eligible for Future
Sale".
 
     Pursuant to the Stock Purchase Agreements entered into in connection with
the Acquisitions, each of the stockholders of the Founding Companies, other than
the Selling Stockholder with respect to the shares he is selling in the
Offering, has agreed with Group 1 Automotive not to sell or otherwise dispose of
shares of Common Stock received in the Acquisitions for a period of two years
from the closing date of the Acquisitions. Pursuant to the Honda Agreement, each
of such stockholders has also agreed not to sell, transfer or otherwise dispose
of such shares of Common Stock, or the voting rights associated therewith,
without the prior written consent of American Honda. In addition, pursuant to an
Underwriting Agreement between Group 1 Automotive, the Selling Stockholder and
the Underwriters, Group 1 Automotive, the executive officers and directors of
Group 1 Automotive and the Selling Stockholder have agreed not to offer, sell or
otherwise dispose of any shares of Common Stock for a period of 180 days from
the date of this Prospectus without the consent of the representatives of the
Underwriters, other than (i) pursuant to employee stock option plans existing,
or upon the conversion or exchange of convertible or exchangeable securities
outstanding, on the date of this Prospectus, or (ii) in connection with and as
consideration for acquisitions of automobile dealerships, provided that the
proposed transferee agrees in writing for the benefit of the Underwriters to be
bound by the foregoing provisions. See "Shares Eligible for Future Sale" and
"Underwriting".
 
                                       24
<PAGE>   25
 
NO PRIOR PUBLIC MARKET AND DETERMINATION OF OFFERING PRICE
 
     Prior to the Offering, there has been no public market for the Common
Stock. The Common Stock has been approved for listing, subject to notice of
issuance, on the New York Stock Exchange. However, there can be no assurance
that an active trading market will develop subsequent to the Offering or, if
developed, that it will be sustained. The initial public offering price of the
Common Stock was determined through negotiations between Group 1 Automotive and
the representatives of the Underwriters and may bear no relationship to the
price at which the Common Stock will trade after the Offering. For information
relating to the factors considered in determining the initial public offering
price, see "Underwriting". Prices for the Common Stock after the Offering may be
influenced by a number of factors, including the liquidity of the market for the
Common Stock, investor perceptions of the Combined Company and the automotive
retailing industry and general economic and other conditions. Sales of
substantial amounts of Common Stock in the public market subsequent to the
Offering could adversely affect the market price of the Common Stock.
 
POSSIBLE VOLATILITY OF PRICE
 
     The market price of the Common Stock could be subject to wide fluctuations
in response to a number of factors, including quarterly variations of operating
results, investor perceptions of the Combined Company and automotive retailing
industry and general economic and other conditions.
 
                                       25
<PAGE>   26
 
                                THE ACQUISITIONS
 
     Group 1 Automotive will acquire all of the issued and outstanding stock of
the Founding Companies in the Acquisitions immediately prior to the consummation
of the Offering pursuant to 13 separate stock purchase agreements (the "Stock
Purchase Agreements"). The Founding Companies are each part of one of the four
separate and distinct Founding Groups.
 
     The Stock Purchase Agreements, provide that acquisition of each Founding
Company is subject to certain conditions including, among others: (i) the
continuing accuracy on the closing date of the representations and warranties of
the applicable Founding Company, the stockholders of such Founding Company and
Group 1 Automotive; (ii) the performance of each of the covenants by the
applicable Founding Company, the stockholders of such Founding Company and Group
1 Automotive, including the removal of certain related party agreements; (iii)
the expiration or termination of the applicable waiting period under the HSR Act
with respect to such acquisition (which has been satisfied); (iv) the obtainment
of all permits, approvals and consents of securities or "blue sky" commissions
of each jurisdiction and of any other governmental agency or authority, where
failure to obtain such permit, approval or consent would have a material adverse
effect; and (v) the entering into an Underwriting Agreement by Group 1
Automotive and the Underwriters in connection with the Offering. The Offering is
conditioned upon, among other things, the consummation of the acquisition of
100% of the Founding Companies.
 
     The Stock Purchase Agreements provide that the parties thereto will not be
liable for the breach, after consummation of the Acquisitions, of any of the
representations, warranties or covenants contained in such agreements, except:
confidentiality obligations, non-competition provisions applicable to certain
stockholders, transfer restrictions on the Common Stock received in the
Acquisitions and termination of all dealership guarantees of stockholder debt.
 
     As part of the Stock Purchase Agreements, certain stockholders of the
Founding Companies have agreed to enter into the employment agreements and/or
the lease agreements described elsewhere in this Prospectus. See
"Management -- Executive Compensation; Employment Agreements", and "Certain
Transactions -- Leases". In connection with their employment with the Combined
Company, certain of such stockholders will receive options to purchase Common
Stock. See "Management -- 1996 Stock Incentive Plan". In addition, certain
stockholders of the Founding Companies, including Messrs. Howard, McCall, Smith
and Hollingsworth and certain of the general managers and key employees of the
Founding Companies, have agreed not to compete with the Combined Company for
five years from the closing of the Acquisitions. See "Management -- Executive
Compensation; Employment Agreements". For a discussion of the consideration to
be received by officers, directors and 5% stockholders in connection with the
Acquisitions, see "Summary -- Consideration Received by Related Parties".
 
     The consideration to be paid by Group 1 Automotive in the Acquisitions is
approximately $5.4 million of cash and 9,074,914 shares of Common Stock. The
Combined Company will record approximately $30.5 million of goodwill in
connection with the Acquisitions. The consideration to be paid by Group 1
Automotive for each of the Founding Companies was determined by negotiations
among the principals of the Founding Companies as to the relative value of each
of the Founding Companies. As such, no one individual determined the
consideration to be paid in connection with the Acquisitions. Group 1 Automotive
and the Founding Companies did not use an independent third party to determine
the relative values of each of the Founding Companies but agreed among
themselves on the values attributable to each of the Founding Companies based on
an evaluation of each of the Founding Companies' operating results and prospects
for growth.
 
     At the time of the execution of the Stock Purchase Agreements in connection
with the Acquisitions, Messrs. Hollingsworth, Howard, McCall and Smith were, in
addition to stockholders of certain of the Founding Companies, directors of
Group 1 Automotive. In addition, at the time of execution of such Stock Purchase
Agreement, Mr. Hollingsworth, was the sole stockholder of Group 1 Automotive. As
a result, Messrs. Hollingsworth, Howard, McCall and Smith might be considered to
have a conflict of interest with
 
                                       26
<PAGE>   27
 
respect to the Acquisitions. The only steps taken to resolve any such conflicts
was ratification of all of the Stock Purchase Agreements by all members of the
Board of Directors of Group 1 Automotive.
 
     Bob Howard East, a corporation wholly-owned by Mr. Howard, has entered into
an agreement to purchase the Tulsa Dealership for approximately $2.5 million.
This purchase price was funded by a $2.5 million loan, bearing interest at the
prime rate plus 100 basis points, from Mr. Howard to Bob Howard East. GM has
denied its approval of Bob Howard East's acquisition of the Tulsa Dealership due
to the Howard Group's failure to meet GM's required CSI score levels. The
Combined Company, through Bob Howard Automall, one of the Founding Companies,
has entered into an agreement to purchase Bob Howard East for the assumption of
all Bob Howard East's liabilities, which consist of the $2.5 million loan from
Mr. Howard. These acquisitions will be consummated immediately upon GM's
approval of such acquisitions.
 
     When the Founding Groups allocated the shares of Common Stock to be
received by each Founding Group in the Acquisitions, it was anticipated that the
acquisition of the Tulsa Dealership would be consummated prior to consummation
of the Acquisitions. Mr. Howard was to receive 592,303 shares of Common Stock in
the Acquisitions as consideration for the Tulsa Dealership. These shares will be
held in escrow pending the acquisition of the Tulsa Dealership.
 
     Upon consummation of Bob Howard East's acquisition of the Tulsa Dealership
and the Combined Company's acquisition of Bob Howard East, the escrowed shares
will be released to Mr. Howard. In this event, the consideration to be paid to
Mr. Howard for the Tulsa Dealership will be (i) the 592,303 shares of Common
Stock (having a value of approximately $4.6 million, which will be profit for
Mr. Howard, based on the initial offering price of $12.00 per share discounted
by 35%) and (ii) the assumption of Bob Howard East's $2.5 million liability to
Mr. Howard. This consideration will be paid to Mr. Howard by the Combined
Company (through Bob Howard Automall).
 
     If these two acquisitions are not consummated with GM's approval within two
years of the Offering: (i) the Combined Company will not acquire the Tulsa
Dealership (ii) Bob Howard East's $2.5 million liability to Mr. Howard will not
be assumed by the Combined Company, (iii) Bob Howard East will retain the right
to acquire the Tulsa Dealership and (iv) rather than being distributed solely to
Mr. Howard, the escrowed shares will be distributed pro rata to the stockholders
of the Founding Companies. This pro rata distribution will be allocated as
follows: the McCall Group, 161,913 shares; the Smith Group, 190,340 shares; the
Howard Group, 207,940 shares; and the Kingwood Group, 32,110 shares. If the
Combined Company does not acquire the Tulsa Dealership and the escrowed shares
are distributed pro rata, the Combined Company will recognize additional
goodwill of approximately $3.0 million.
 
     The escrowed shares will remain outstanding regardless of whether the
acquisition of the Tulsa Dealership is consummated, and the Combined Company
will receive no additional consideration or assets if such shares are
distributed pro rata as described above. If the Combined Company's acquisition
of the Tulsa Dealership is not consummated, the fair value of the Howard Group's
contribution to the Combined Company will decrease, and the fair value of the
Smith Group's, McCall Group's and Kingwood Group's contributions to the Combined
Company will remain the same. The treatment of the escrowed shares and the terms
and conditions upon which such shares are to be released were the subject of
arms-length negotiations among the Founding Groups. The Board of Directors of
Group 1 Automotive believes that the potential pro rata distribution of the
escrowed shares to the stockholders of the Founding Companies is a fair
reallocation of the fixed number of shares of Common Stock to be issued to the
Founding Groups in the Acquisitions, based upon the increased relative
contribution of the McCall, Smith and Kingwood Groups and the decreased relative
contribution of the Howard Group.

(1) The value of the shares of Common Stock issued in connection with the
    Acquisitions (other than the Common Stock to be sold by the Selling
    Stockholder) was discounted by 35% from the initial public offering price of
    $12.00 to give effect to the two year lock-up that each stockholder of the
    Founding Companies entered into in connection with the Acquisitions. This
    discount was based on an independent valuation study as to the impact of the
    restrictions on the value of the Common Stock.
 
(2) Includes 592,303 shares of Common Stock issued to Mr. Howard in the
    Acquisitions and placed in escrow according to the terms described above.
 
     In connection with the Acquisitions, the following directors, officers and
stockholders owning more than 5% of the Common Stock together with their spouses
and affiliates will receive shares of Common Stock as follows: Mr.
Hollingsworth -- 196,368 shares of Common Stock (excluding the 350,000 shares of
Common Stock that Mr. Hollingsworth currently owns); Mr. Howard -- 2,956,955
shares of Common Stock; Mr. McCall -- 1,461,031 shares of Common Stock; Mr.
Smith -- 679,181 shares of Common Stock; Mr. Duncan -- 196,368 shares of Common
Stock; Mr. Whalen -- 774,040 shares of Common Stock. In addition, Mr. Howard
will receive $2.3 million in cash in the Acquisitions. See "Principal and
Selling Stockholders".
 
     In connection with Acquisitions, all related party receivables and payables
are being settled. Such transactions will result in a net payment of $19,720, as
of June 30, 1997, by the McCall Group to Mr. McCall. Additionally, as part of
the Acquisitions, certain Founding Companies will distribute an aggregate of
approximately $6.2 million from pre-acquisition S corporation accumulated
adjustment accounts to their stockholders as follows: $4.5 million to the
stockholders of the Howard Group (including approximately $3.4 million to Mr.
Howard), $1.3 million to the stockholders of the Smith Group (including $337,500
to Mr. Smith) and $0.4 million to the stockholders of the Kingwood Group
(including $97,104 to Mr. Hollingsworth and $97,104 to Mr. Duncan). In addition,
in connection with the Acquisitions, Mr. Howard intends to acquire certain
nonoperating assets (recreational vehicles and properties) owned by the Howard
Group and pay the Combined Company approximately $2.0 million. Group 1
Automotive believes that $2.0 million approximates the fair market value of the
assets. Group 1 Automotive believes that these assets approximate fair market
value because the assets are being sold to Mr. Howard at a price equal to their
net book value and the majority of such assets were acquired by the Howard Group
within the last 18 months.
 
     In connection with the Acquisitions, Group 1 Automotive anticipates, for
the Combined Company, increases in revenues and decreases in cost of sales
related to certain third party products sold by the dealerships. Certain of the
principals of the Founding Companies currently have agreements in place that
decrease the fees and commissions paid to the dealerships for sales of certain
finance and insurance products and increase the cost of certain aftermarket
products. These arrangements resulted in the payment of $732,916 to Mr. McCall
and $728,647 to Mr. Whalen during the year ended December 31, 1996 and $357,144
to Mr. McCall and $404,020 to Mr. Whalen during the six months ended June 30,
1997. Upon completion of the Acquisitions, such agreements will be terminated
and the Combined Company will recognize an immediate increase in revenues and
decrease in cost of sales related to the products sold.

                                USE OF PROCEEDS
 
     The net proceeds to the Combined Company from the sale of 4,428,136 shares
of Common Stock offered hereby are estimated to be $45.1 million ($53.1 million
if the Underwriters' over-allotment option is exercised in full) after deducting
the underwriting discount and estimated expenses of the Offering (excluding
approximately $700,000 of Offering expenses previously paid by the Company). Of
the net proceeds, approximately $5.4 million will be used to pay the cash
portion of the purchase price for the Acquisitions. In addition, approximately
$35.5 million will be used to repay indebtedness with maturities of less than
one year with a weighted average interest rate of approximately 8.0%. The
remainder of the net proceeds will be used for working capital and general
corporate purposes.
 
     Group 1 Automotive intends to pursue acquisitions in the future which will
be financed with cash, Common Stock or a combination of both cash and Common
Stock. The Combined Company has identified and has held preliminary discussions
with numerous potential acquisition candidates. In addition, Group 1 Automotive
has recently entered into definitive agreements to acquire, subject to
manufacturer approval and a due diligence investigation, two dealership
locations consisting of Acura, Buick, Dodge, Ford, Mercedes-Benz, Nissan and
Volvo dealerships in Texas for aggregate payments to the sellers of
approximately $9.0 million in cash. These two acquisitions, if consummated,
would also require the Combined Company to incur approximately $13.0 million of
floorplan indebtedness in connection with the purchase of the vehicle
inventories of the dealerships. The agreements are subject to a number of
significant conditions, including Manufacturer approval and completion of a due
diligence review of the dealerships. There can be no assurance that the
conditions will be satisfied or that the transactions will be consummated. Group
1 Automotive has negotiated and executed an arrangement letter with Chase
Securities, Inc. and Comerica Bank for the Combined Company's $125 million
credit facility. The Credit Facility will be used for general corporate
purposes, acquisitions, capital expenditures, working capital and floorplan
financing. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations -- Combined Founding Groups' Commitments -- Credit
Facility".
 
                                DIVIDEND POLICY
 
     Group 1 Automotive intends to retain all of the Combined Company's earnings
to finance the growth and development of its business, including future
acquisitions, and does not anticipate paying any cash dividends on its Common
Stock for the foreseeable future. Any future change in the Combined Company's
dividend policy will be made at the discretion of the Board of Directors of the
Combined Company and will depend upon the Combined Company's operating results,
financial condition, capital requirements, general business conditions and such
other factors as the Board of Directors deems relevant. In addition, the Credit
Facility will include restrictions on the ability of the Combined Company to pay
dividends without the consent of the lender. See "Description of Capital Stock".

                                    DILUTION
 
     The pro forma net tangible book value of the Combined Company as of June
30, 1997 was $1.63 per share of Common Stock. Pro forma net tangible book value
per share is determined by dividing the pro forma tangible net worth of the
Combined Company (pro forma tangible assets less pro forma total liabilities) by
the total number of outstanding shares of Common Stock. After giving effect to
the sale by Group 1 Automotive of the 4,428,136 shares offered hereby and the
receipt of an estimated $45.1 million of net proceeds from the Offering (based
on the initial public offering price of $12.00 per share and net of the
underwriting discounts and estimated expenses of the Offering, excluding
approximately $700,000 of Offering expenses previously paid by the Company), pro
forma net tangible book value of the Combined Company at June 30, 1997 would
have been $4.30 per share. This represents an immediate increase in pro forma
net tangible book value of $2.67 per share to existing stockholders and an
immediate dilution of $7.70 per share to the new investors purchasing Common
Stock in the Offering. (If all outstanding stock options were exercised, pro
forma tangible net book value would be further diluted by $.13 per share to
$4.17 per share.) The following table illustrates the per share dilution:

Stock Incentive Plan as of the completion of the Offering, of which 661,700 will
be exercisable at the initial public offering price per share and 565,000 will
be exercisable at $2.90 per share. In addition, 773,300 additional shares of
Common Stock are reserved for future issuance under the 1996 Stock Incentive

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     The following discussion should be read in conjunction with the Founding
Groups' Financial Statements and related notes thereto and "Selected Financial
Data" appearing elsewhere in this Prospectus.
 
OVERVIEW
 
     Group 1 Automotive was founded to become a leading operator and
consolidator in the highly fragmented automotive industry. Immediately prior to
the closing of the Offering, Group 1 Automotive will acquire the Founding
Companies. The Combined Company will own 30 automobile dealerships located in
Texas and Oklahoma representing 21 American and Asian brands including Acura,
Chevrolet, Chrysler, Dodge, Eagle, GMC, Honda, Isuzu, Jeep, Kia, Lexus, Lincoln,
Mazda, Mercury, Mitsubishi, Nissan, Oldsmobile, Plymouth, Pontiac, Suzuki and
Toyota. Additionally, the Combined Company will provide maintenance and repair
services at its 30 dealerships and five collision service centers. The Combined
Company will utilize approximately 500 service bays in providing these services.
The Founding Groups are experiencing significant momentum in their financial
results. From 1994 to 1996, the Founding Groups' pro forma revenues increased by
$172.5 million, or 26.4%, to $825.6 million from $653.1 million. During this
period, pro forma gross profit increased $27.5 million, or 32.2%, to $112.9
million from $85.4 million, to 13.7% from 13.1% of revenues. Group 1 Automotive
expects that a significant portion of the Combined Company's future growth will
be derived from acquisitions of additional dealerships.
 
     Group 1 Automotive plans to achieve its goal of becoming a leading
consolidator, while maintaining its high operating standards in the automotive
retailing industry, by (i) emphasizing growth through acquisitions and (ii)
implementing an operating strategy that focuses on decentralized dealership
operations, nationally centralized administrative functions, the expansion of
higher margin businesses, a commitment to customer service and the
implementation of new technology initiatives. By complementing the Founding
Groups' industry leaders, management talent and proven operating capabilities
with the Combined Company's corporate management team which is experienced in
achieving and managing long-term growth in a consolidation environment, Group 1
Automotive believes that the Combined Company is in a strong position to execute
this strategy.
 
     The Combined Company will have diverse sources of revenues, including: new
car sales, new truck sales, used car sales, used truck sales, manufacturer
remarketed vehicle sales, parts sales, service sales, collision repair services,
finance fees, insurance commissions, extended service contract sales,
documentary fees and after-market product sales. Sales revenues include sales to
retail customers, other dealers and wholesalers. Other dealership revenue
includes revenue from the sale of financing, insurance and extended service
contracts, net of a provision for anticipated chargebacks and documentary fees
charged to customers.
 
     The Combined Company's gross profit will vary as the Combined Company's
merchandise mix (the mix between new vehicle sales, used vehicle sales, parts
and service sales, collision repair services and other dealership revenues)
changes. The gross margin realized by the Founding Groups on the sale of its
products and services generally varies between approximately 6.5% and 60.0%,
with new vehicle sales generally resulting in the lowest gross margin and parts
and service sales generally resulting in the highest gross margin. Revenues from
other dealership revenues contribute a disproportionate share of gross,
operating and pre-tax margins. When the Combined Company's new vehicle sales
increase or decrease at a rate greater than the Combined Company's other revenue
sources, the Combined Company's gross margin will respond inversely. Factors
such as seasonality, weather, cyclicality and manufacturers' advertising and
incentives may impact the Combined Company's merchandise mix and, therefore
influence the Combined Company's gross margin.
 
     Selling, general and administrative expenses consist primarily of
compensation for sales, administrative, finance and general management
personnel, rent, marketing, insurance and utilities. Interest expense consists
of interest charges on interest-bearing debt, including floorplan inventory
financing, net
 
                                       36

of interest credits received from certain manufacturers and interest income
earned. The Founding Groups have been managed throughout the periods presented
as independent private companies and their results of operations reflect
different tax structures (S Corporations and C Corporations) which have
influenced, among other things, their historical levels of owners' compensation.
These owners and certain key employees have agreed to certain reductions in
their compensation and benefits in connection with the organization of the
Combined Company.
 
     Group 1 Automotive, which has conducted no operations to date other than in
connection with the Acquisition and the Offering, intends to integrate certain
functions over a period of time and install practices that have been successful
at other franchises and in other retail segments ("best practices"). This
integration and installation of best practices may present opportunities to
increase revenues and reduce costs but may also necessitate additional costs and
expenditures for corporate administration, including expenses necessary to
implement the Combined Company's acquisition strategy. These various costs and
possible cost-savings and revenue enhancements may make historical operating
results not comparable to, or indicative of, future performance.
 
PRO FORMA COMBINED FOUNDING GROUPS' DATA
 
     The pro forma combined Founding Groups' data for 1994, 1995 and 1996 and
the six months ended June 30, 1996, and June 30, 1997, do not purport to present
the combined Founding Groups in accordance with generally accepted accounting
principles, but represent a summation of certain data of the individual Founding
Groups on an historical basis including the effects of the pro forma
adjustments. This data will not be comparable to and may not be indicative of
the Combined Company's post-combination results of operations because (i) the
Founding Groups were not under common control of management and had different
tax structures (S Corporations and C Corporations) during the periods presented
and (ii) the Combined Company will use the purchase method to establish a new
basis of accounting to record the Acquisitions.
 
     The following tables sets forth certain unaudited pro forma combined data
of the Founding Groups for the periods indicated:

SIX MONTHS ENDED JUNE 30, 1997 COMPARED TO SIX MONTHS ENDED JUNE 30, 1996
 
     REVENUES. Revenues increased $45.9 million, or 11.4%, from $404.4 million
for the six months ended June 30, 1996 to $450.3 million for the six months
ended June 30, 1997. New vehicle sales increased $24.6 million, or 10.8%, from
$227.2 million for the six months ended June 30, 1996 to $251.8 million for the
six months ended June 30, 1997. The increase is primarily attributable to new
franchise operations, strong customer acceptance of the Founding Groups'
products, particularly Lexus and Nissan, and successful marketing efforts. The
new franchise operations include a Dodge franchise acquired by the Howard Group
in May 1996 ("Bob Howard Dodge") and a new Nissan franchise awarded to the Smith
Group during 1996. Used vehicle sales increased $19.0 million, or 14.7%, from
$129.6 million for the six months ended June 30, 1996 to $148.6 million for the
six months ended June 30, 1997. This increase is primarily attributable to the
new franchise operations and successful marketing efforts. Parts and service
sales increased $1.7 million, or 4.6%, from $36.7 million for the six months
ended June 30, 1996 to $38.4 million for the six months ended June 30, 1997. The
increase is attributable to the new franchise operations and a growing customer
base at the McCall Lexus franchise. Other dealership revenues increased $0.6
million or 5.5% from $10.9 million for the six months ended June 30, 1996 to
$11.5 million for the six months ended June 30, 1997. The increase is due
primarily to an increase in the number of retail new and used vehicle sales.
 
     GROSS PROFIT. Gross profit increased $5.4 million, or 9.7% from $55.9
million for the six months ended June 30, 1996 to $61.3 million for the six
months ended June 30, 1997. The increase is attributable to increased sales
offset by a reduced gross margin. The gross margin declined from 13.8% for the
six months ended June 30, 1996 to 13.6% for the six months ended June 30, 1997.
The reduced gross margin resulted primarily from a decline in used vehicle gross
margin, offset by an increase in new vehicle and parts and service gross
margins.
 
  YEAR ENDED DECEMBER 31, 1996 COMPARED TO YEAR ENDED DECEMBER 31, 1995
 
     REVENUES. Revenues increased $96.2 million, or 13.2%, from $729.4 million
for the year ended December 31, 1995 to $825.6 million for the year ended
December 31, 1996. New vehicle revenues
 
                                       38

increased $47.0 million, or 11.1%, from $422.3 million for the year ended
December 31, 1995 to $469.3 million for the year ended December 31, 1996. This
increase is primarily attributable to increased sales at all but one of the
Founding Groups with the McCall Group accounting for $40.6 million of the
increase. New and expanded franchise operations, primarily the Howard Group's
new Dodge franchise, successful marketing efforts and strong customer acceptance
of the Founding Groups' products, particularly Toyota, Lexus and Chevrolet,
contributed to the increase. The Smith Group had an $8.0 million decline in new
vehicle revenues caused by reduced unit sales at its Dallas Nissan franchise.
Used vehicle revenues increased $35.6 million, or 16.0%, from $222.4 million for
the year ended December 31, 1995 to $258.0 million for the year ended December
31, 1996. All of the Founding Groups' had increases in used vehicle revenues
with the McCall Group accounting for $22.6 million of the increase. The increase
is attributable primarily to a strong used vehicle market and successful
marketing efforts. Parts and service sales increased $11.6 million, or 17.7%,
from $65.6 million for the year ended December 31, 1995 to $77.2 million for the
year ended December 31, 1996. The increase is primarily attributable to new and
expanded operations at McCall Lexus, and increased vehicle sales. Other
dealership revenues increased $2.1 million or 11.1% from $19.0 million for the
year ended December 31, 1995 to $21.1 million for the year ended December 31,
1996. The increase is due primarily to an increase in the number of retail new
and used vehicle sales.
 
     GROSS PROFIT. Gross profit increased $15.6 million, or 16.0%, from $97.3
million for the year ended December 31, 1995 to $112.9 million for the year
ended December 31, 1996. The increase is attributable to increased revenues and
an increase in gross margin from 13.3% for the year ended December 31, 1995 to
13.7% for the year ended December 31, 1996. The increase in gross margin is
primarily due to a change in the merchandise mix as parts and service sales
became a greater percentage of total revenues. Additionally, gross margin on new
retail vehicle sales increased from 6.9% for the year ended December 31, 1995 to
7.3% for the year ended December 31, 1996. The gross margin on used retail
vehicle sales increased from 9.5% for the year ended December 31, 1995, to 9.7%
for the year ended December 31, 1996. However, gross margin on parts and service
sales decreased from 47.9% for the year ended December 31, 1995 to 46.6% for the
year ended December 31, 1996.
 
  YEAR ENDED DECEMBER 31, 1995 COMPARED TO YEAR ENDED DECEMBER 31, 1994
 
     REVENUES. Revenues increased $76.3 million, or 11.7%, from $653.1 million
for the year ended December 31, 1994 to $729.4 million for the year ended
December 31, 1995. New vehicle revenues increased $30.6 million, or 7.8% from
$391.7 million for the year ended December 31, 1994 to $422.3 million for the
year ended December 31, 1995. The increase is the result of increased sales at
all but one of the Founding Groups. The increase in revenue is attributable to
new franchise operations at Bob Howard Honda/Acura which was acquired during
1994, successful marketing efforts and strong customer acceptance of the
Founding Groups' products. Used vehicle revenues increased $38.2 million, or
20.7%, from $184.2 million for the year ended December 31, 1994 to $222.4
million for the year ended December 31, 1995. The increase is primarily
attributable to the new franchise operations and successful marketing efforts.
Parts and service sales increased $4.6 million, or 7.5%, from $61.0 million for
the year ended December 31, 1994 to $65.6 million for the year ended December
31, 1995. The increase is primarily attributable to the new dealership
operations and increased vehicle sales. Other dealership revenues increased $2.8
million or 17.3% from $16.2 million for the year ended December 31, 1994 to
$19.0 million for the year ended December 31, 1995. The increase is due
primarily to an increase in the number of retail new and used vehicle sales.
 
     GROSS PROFIT. Gross profit increased $11.9 million, or 13.9%, from $85.4
million for the year ended December 31, 1994 to $97.3 million for the year ended
December 31, 1995. The increase is attributable to increased revenues and an
improved gross margin. Changes in the merchandise mix and certain product gross
margins resulted in the Founding Groups' gross margin increasing from 13.1% for
the year ended December 31, 1994 to 13.3% for the year ended December 31, 1995.
The gross margin on new retail vehicle sales increased from 6.6% for the year
ended December 31, 1994 to 6.9% for the year ended December 31, 1995. The gross
margin for used retail vehicle sales declined from 9.9% for the year

ended December 31, 1994 to 9.5% for the year ended December 31, 1995. Parts and
service gross margin increased from 47.2% for the year ended December 31, 1994
to 47.9% for the year ended December 31, 1995.
 
COMBINED FOUNDING GROUPS' COMMITMENTS
 
  CREDIT FACILITY
 
     Group 1 Automotive has negotiated and executed an arrangement letter with
Chase Securities, Inc. and Comerica Bank for a $125 million Credit Facility
which may be used by the Combined Company for acquisitions, floorplan financing,
general corporate purposes, capital expenditures and working capital. The
arrangement letter provides for Chase Securities, Inc. to use commercially
reasonable efforts to assemble a syndicate of financial institutions subsequent
to the Offering. Chase Securities, Inc. and Comerica Bank have committed for
approximately 50% of the Credit Facility. At the Combined Company's option, the
Credit Facility may bear interest based on a designated London Interbank
Offering Rate plus a margin ranging from 150 to 275 basis points. The Credit
Facility matures three years from the date the loan is closed and will be
secured by certain of the Combined Company's assets.
 
  FLOORPLAN FINANCING
 
     As of June 30, 1997, the Founding Groups had approximately $97.5 million of
floorplan debt outstanding. Group 1 Automotive intends to repay $35.5 million of
floorplan indebtedness with the proceeds of the Offering. Currently, the
Founding Group's floorplan financing is provided by seven sources. Upon
consummation of the Offering, all of the Combined Company's floorplan financing
will benefit from interest rate reductions. Rate reductions have already become
effective with respect to approximately 75% of the Founding Groups' floorplan
debt. The current reductions range between 25 and 225 basis points.
Additionally, subsequent to the Offering, the Combined Company intends to
refinance approximately $50 million in floorplan financing with the Credit
Facility.
 
  LEASES
 
     The Founding Groups lease various facilities and equipment under operating
lease agreements, including leases with related parties. In connection with the
Acquisitions, Group 1 Automotive intends to replace certain of the Founding
Groups' leases with new leases that will have terms of 30 years and will be
cancelable at the Combined Company's option ten years from execution of the
lease and at the end of each subsequent five year period. Such leases will
initially have the same rent as the currently existing leases and will be
subject to increase every five years based on a percentage of the Consumer Price
Index. See "Certain Transaction -- Leases". Future minimum lease payments for
existing operating leases are as follows: $6.6 million in 1997, $6.5 million in
1998, $6.0 million in 1999, $5.2 million in 2000 and $3.9 million in 2001.

  SIX MONTHS ENDED JUNE 30, 1997 COMPARED TO SIX MONTHS ENDED JUNE 30, 1996
 
     REVENUES. Revenues increased $13.3 million, or 9.5%, from $140.7 million
for the six months ended June 30, 1996 to $154.0 million for the six months
ended June 30, 1997. New vehicle sales increased $2.4 million, or 2.9%, from
$82.5 million for the six months ended June 30, 1996 to $84.9 million for the
six months ending June 30, 1997. The increase is primarily attributable to sales
generated by Bob Howard Dodge and the Toyota franchise which were partially
offset by reduced sales at Bob Howard Automall. Used vehicle sales increased
$10.4 million, or 23.6%, from $44.0 million for the six months ended June 30,
1996 to $54.4 million for the six months ended June 30, 1997. This increase is
attributable to sales generated by Bob Howard Dodge in addition to increased
sales at all of the Howard Group's other franchises. Parts and service sales
increased $0.7 million, or 6.9%, from $10.1 million for the six months ended
June 30, 1996 to $10.8 million for the six months ended June 30, 1997. The
increase is attributable primarily to sales generated by Bob Howard Dodge. Other
dealership revenues increased $0.1 million or 2.6% from $3.9 million for the six
months ended June 30, 1996 to $4.0 million for the six months ended June 30,
1997. The increase is due primarily to an increase in the number of retail used
vehicle sales while the number of retail new vehicle sales was stable.
 
     GROSS PROFIT. Gross profit increased $0.9 million, or 4.7%, from $19.0
million for the six months ended June 30, 1996 to $19.9 million for the six
months ended June 30, 1997. The increase is attributable primarily to increased
sales, offset partially by reduced vehicle gross margins at certain of the
Howard Group's franchises. The Howard Group's gross margin declined from 13.5%
for the six months ended June 30, 1996 to 12.9% for the six months ended June
30, 1997 due primarily to increased competitive pressures in the marketplace.

     SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Selling, general and
administrative expenses increased $1.5 million or 10.0% from $15.0 million for
the six months ended June 30, 1996 to $16.5 million for the six months ended
June 30, 1997. The increase is primarily attributable to expenses incurred by
Bob Howard Dodge, which was acquired late in the second quarter of 1996.
Selling, general and administrative expenses, as a percentage of total revenues,
remained constant at 10.7% for the six month periods ended June 30, 1996 and
June 30, 1997.
 
     INTEREST EXPENSE, NET. Interest expense, net, increased $0.1 million or
14.3% from $0.7 million for the six months ended June 30, 1996 to $0.8 million
for the six months ended June 30, 1997. Interest expense increased primarily due
to interest expense incurred by Bob Howard Dodge and increased vehicle
inventories carried at certain of the Howard Group's franchises.
 
YEAR ENDED DECEMBER 31, 1996 COMPARED TO YEAR ENDED DECEMBER 31, 1995
 
     REVENUES. Revenues increased by $28.0 million, or 11.0% from $254.0 million
for the year ended December 31, 1995 to $282.0 million for the year ended
December 31, 1996. New vehicle sales increased $13.8 million, or 9.1%, from
$151.2 million for the year ended December 31, 1995 to $165.0 million for the
year ended December 31, 1996. The increase is primarily attributable to strong
sales at the Chevrolet franchise and the acquisition of Bob Howard Dodge, offset
by reduced sales at Bob Howard Automall. Used vehicle revenues increased $9.1
million, or 11.5%, from $79.4 million for the year ended December 31, 1995 to
$88.5 million for the year ended December 31, 1996. This increase is
attributable to the acquisition of Bob Howard Dodge and the Howard Group's
successful marketing efforts at all of the Howard Group's other franchises.
Parts and service sales increased $4.3 million, or 25.4%, from $16.9 million for
the year ended December 31, 1995 to $21.2 million for the year ended December
31, 1996. The increase is attributable to increased sales at each of the Howard
Group's franchises and new sales from the acquisition of Bob Howard Dodge. Other
dealership revenues increased $1.0 million or 15.6% from $6.4 million for the
year ended December 31, 1995 to $7.4 million for the year ended December 31,
1996. The increase is due primarily to an increase in the number of retail new
and used vehicle sales.
 
     GROSS PROFIT. Gross profit increased by $5.4 million, or 16.8%, from $32.2
million for the year ended December 31, 1995 to $37.6 million for the year ended
December 31, 1996. The increase is attributable to increased sales and
improvement in the Howard Group's gross profit margin from 12.7% for the year
ended December 31, 1995 to 13.3% for the year ended December 31, 1996. The gross
margin improved as revenues from parts and service and other dealership revenues
became a greater percentage of total revenues.
 
     SELLING, GENERAL AND ADMINISTRATION EXPENSES. Selling, general and
administration expenses increased $4.6 million, or 17.6%, from $26.2 million for
the year ended December 31, 1995 to $30.8 million for the year ended December
31, 1996. The increase is primarily attributable to costs related to the newly
acquired Bob Howard Dodge and variable incentive pay to employees which is
related to the increase in revenues. As a percentage of total revenues, selling,
general and administrative expenses increased from 10.3% for the year ended
December 31, 1995 to 10.9% for the year ended December 31, 1996.
 
     INTEREST EXPENSE, NET. Interest expense, net, decreased $0.4 million, or
25.0%, from $1.6 million for the year ended December 31, 1995 to $1.2 million
for the year ended December 31, 1996. The decrease is attributable to an
approximately 50 basis point decrease in the average floorplan interest rate and
increased manufacturer assistance, partially offset by interest expense incurred
by the newly acquired Bob Howard Dodge.
 
YEAR ENDED DECEMBER 31, 1995 COMPARED TO YEAR ENDED DECEMBER 31, 1994
 
     REVENUES. Revenues increased by $26.7 million, or 11.7%, from $227.3
million for the year ended December 31, 1994 to $254.0 million for the year
ended December 31, 1995. New vehicle sales increased $14.4 million, or 10.5%,
from $136.8 million for the year ended December 31, 1994 to
 
                                       42
<PAGE>   43
 
$151.2 million for the year ended December 31, 1995. The increase is primarily
attributable to strong sales growth of the Chevrolet franchise due to strong
customer acceptance of Chevrolet products and successful marketing efforts, and
the inclusion of a full year of revenues for the Honda and Acura franchises
acquired during 1994. Used vehicle sales increased $9.5 million, or 13.6%, from
$69.9 million for the year ended December 31, 1994 to $79.4 million for the year
ended December 31, 1995. This increase is primarily attributable to successful
marketing efforts and the inclusion of a full year of revenues for the Honda and
Acura franchises acquired during 1994. Parts and service sales increased $2.5
million or 17.4% from $14.4 million for the year ended December 31, 1994 to
$16.9 million for the year ended December 31, 1995. The overall increase is
primarily attributable to continued steady growth driven by increased vehicle
sales. Other dealership revenues increased $0.2 million or 3.2% from $6.2
million for the year ended December 31, 1994 to $6.4 million for the year ended
December 31, 1995. The increase is due primarily to an increase in the number of
retail new and used vehicle sales.
 
     GROSS PROFIT. Gross profit increased by $3.9 million, or 13.8%, from $28.3
million for the year ended December 31, 1994 to $32.2 million for the year ended
December 31, 1995. The increase is primarily attributable to increased sales.
Additionally, the gross margin improved from 12.4% for the year ended December
31, 1994 to 12.7% for the year ended December 31, 1995 due primarily to parts
and service revenues becoming a greater percentage of total revenues.
 
     SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Selling, general and
administrative expenses increased $1.9 million, or 7.8%, from $24.3 million for
the year ended December 31, 1994 to $26.2 million for the year ended December
31, 1995. The increase is primarily attributable to variable incentive pay to
employees which is related directly to the increase in revenues. Selling,
general and administrative expenses declined as a percentage of revenues from
10.7% for the year ended December 31, 1994 to 10.3% for the year ended December
31, 1995.
 
     INTEREST EXPENSE, NET. Interest expense, net, increased $0.5 million, or
45.5%, from $1.1 million for the year ended December 31, 1994 to $1.6 million
for the year ended December 31, 1995. The increase is primarily attributable to
an approximately 170 basis point increase in the average floorplan interest rate
and an increase in inventory to support growing retail sales.

  CASH FLOWS
 
     Total cash and cash equivalents at June 30, 1997, were $9.9 million.
 
     For the three year period ended December 31, 1996, the Howard Group
generated $18.7 million in net cash from operating activities, primarily from
net income plus depreciation and amortization. Net cash flow from operating
activities remained stable for the years ended December 31, 1995 and December
31, 1996.
 
                                       43
<PAGE>   44
 
     Net cash from operating activities increased from $1.9 million for the six
months ended June 30, 1996 to $2.4 million for the six months ended June 30,
1997, primarily due to change in inventories, floor plan financing and accounts
payable and accrued liabilities.
 
     The change in net cash used in investing activities was attributable to
purchases of property and equipment and the purchases of the Honda and Acura
franchises in 1994 and the Dodge franchise in 1996.
 
     The change in net cash used in financing activities was primarily
attributable to dividends paid in excess of cash received from contributions and
stock issuances.
 
  FLOORPLAN FINANCING
 
     The Howard Group currently obtains floorplan financing for its vehicle
inventory primarily through General Motors Acceptance Corporation ("GMAC"). As
of June 30, 1997, the Howard Group had approximately $37.8 million of floorplan
financing outstanding. The debt bears interest at a rate of prime minus 75 basis
points. Interest expense on floorplan notes payable, before manufacturer
interest assistance, totaled approximately $2.4 million, $3.4 million and $3.1
million for the year ended December 31, 1994, 1995 and 1996. Manufacturer
interest assistance, which is recorded as a reduction to interest expense,
totaled approximately $1.4 million, $1.9 million and $2.0 million for the years
ended December 31, 1994, 1995 and 1996.
 
  LEASES
 
     The Howard Group leases various real estate, facilities and equipment under
operating lease agreements, including leases with related parties. In connection
with the Acquisitions, the Howard Group intends to replace certain existing
leases with leases that have terms of 30 years and will be cancellable at the
Combined Company's option ten years from execution of the lease and at the end
of each subsequent five year period. Such leases initially will have the same
rent as the existing leases and will be subject to increases every five years
based on a percentage of the Consumer Price Index. See "Certain
Transactions -- Leases". Future minimum lease payments of existing operating
leases are as follows: $2.9 million in 1997, $2.9 million in 1998, $2.5 million
in 1999, $2.2 million in 2000 and $1.7 million in 2001.
 
  OTHER
 
     The Howard Group had working capital of $6.4 million as of December 31,
1996. Historically, the Howard Group has funded its operations with internally
generated cash flow and borrowings from lenders. While there can be no
assurance, based on current facts and circumstances, management believes it has
adequate cash flows and financing alternatives to fund its current operations.

  SIX MONTHS ENDED JUNE 30, 1997 COMPARED TO SIX MONTHS ENDED JUNE 30, 1996
 
     REVENUES. Revenues increased $9.8 million, or 7.1%, from $137.2 million for
the six months ended June 30, 1996 to $147.0 million for the six months ended
June 30, 1997. New vehicle sales increased $3.0 million, or 3.8%, from $78.6
million for the six months ended June 30, 1996 to $81.6 million for the six
months ending June 30, 1997. The increase is primarily attributable to
successful marketing efforts and continued strong customer support of Lexus
products partially offset by a decline in sales at the Toyota franchise, due to
product availability limitations. Used vehicle sales increased $5.6 million, or
12.7%, from $44.2 million for the six months ended June 30, 1996 to $49.8
million for the six months ended June 30, 1997. This increase is primarily
attributable to successful marketing efforts. Parts and service sales increased
$1.3 million, or 11.8%, from $11.0 million for the six months ended June 30,
1996 to $12.3 million for the six months ended June 30, 1997. The increase is
primarily attributable to growth in vehicle sales at the Lexus franchise,
resulting in new parts and service customers. Other dealership revenues declined
$0.1 million or 3.0% from $3.3 million for the six months ended June 30, 1996 to
$3.2 million for the six months ended June 30, 1997. The decline is due
primarily to a slight decline in the number of retail new and used vehicle
sales. New vehicle revenues increased despite the decline in the number of units
sold as higher cost Lexus franchise sales more than offset the reduced Toyota
franchise sales.
 
     GROSS PROFIT. Gross profit increased $0.8 million, or 4.2%, from $18.9
million for the six months ended June 30, 1996 to $19.7 million for the six
months ended June 30, 1997. The increase is due to increased sales offset by a
decline in the gross margin from 13.8% for the six months ended June 30, 1996 to
13.4% for the six months ended June 30, 1997. The decline in gross margin is
primarily due to reduced margins on used vehicle sales at the Toyota franchise
as new sales management reduced the inventory level, which also reduced interest
expense.
 
     SELLING, GENERAL AND ADMINISTRATIVE EXPENSE. Selling, general and
administrative expenses increased $0.5 million, or 2.9%, from $17.0 million for
the six months ended June 30, 1996 to
 
                                       45
<PAGE>   46
 
$17.5 million for the six months ended June 30, 1997. The increase is primarily
attributable to variable incentive pay to employees which is related directly to
the increase in the revenues. As a percentage of total revenues, selling,
general and administrative expenses declined from 12.4% for the six months ended
June 30, 1996 to 11.9% for the six months ended June 30, 1997.
 
     INTEREST EXPENSE, NET. Interest expense, net, decreased $1.0 million, or
66.7%, from $1.5 million for the six months ended June 30, 1996 to $0.5 million
for the six months ended June 30, 1997. The decrease is attributable to
increased manufacturer interest assistance and reduced inventory levels.
 
  YEAR ENDED DECEMBER 31, 1996 COMPARED TO YEAR ENDED DECEMBER 31, 1995
 
     REVENUES. Revenues increased by $69.6 million, or 31.8%, from $218.9
million for the year ended December 31, 1995 to $288.5 million for the year
ended December 31, 1996. New vehicle sales increased $40.6 million, or 32.3%,
from $125.8 million for the year ended December 31, 1995 to $166.4 million for
the year ended December 31, 1996. The increase is primarily attributable to
successful marketing efforts, continued strong customer support of Toyota and
Lexus products, the installation of a new management team at the Lexus franchise
in February 1996 and showroom expansions at both the Toyota and Lexus franchises
in 1996. Used vehicle revenues increased $22.6 million, or 33.1%, from $68.3
million for the year ended December 31, 1995 to $90.9 million for the year ended
December 31, 1996. This increase is attributable to successful marketing
efforts. Parts and service sales increased $5.1 million, or 26.3%, from $19.4
million for the year ended December 31, 1995, to $24.5 million for the year
ended December 31, 1996. The increase is primarily attributable to the addition
of a state-of-the-art collision service center at the Lexus franchise in late
1995 and increased vehicle sales. Other dealership revenues increased $1.5
million or 28.3% from $5.3 million for the year ended December 31, 1995 to $6.8
million for the year ended December 31, 1996. The increase is due primarily to
an increase in the number of retail new and used vehicle sales.
 
     GROSS PROFIT. Gross profit increased by $8.8 million, or 29.1%, from $30.2
million for the year ended December 31, 1995 to $39.0 million for the year ended
December 31, 1996. The increase is attributable to increased sales, net of a
minor decline in gross margin from 13.8% for the year ended December 31, 1995 to
13.5% for the year ended December 31, 1996. The slight decline in gross margin
is primarily due to an increase in new and used vehicle revenues as a percentage
of total revenues.
 
     SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Selling, general and
administrative expenses increased $7.3 million, or 26.3%, from $27.8 million for
the year ended December 31, 1995 to $35.1 million for the year ended December
31, 1996. The increase is primarily attributable to variable incentive pay to
employees and increased marketing expense, both of which are related to the
increase in revenues. As a percentage of revenues, selling, general and
administrative expenses decreased from 12.7% for the year ended December 31,
1995 to 12.1% for the year ended December 31, 1996 as fixed costs were spread
over a larger pool of revenue.
 
     INTEREST EXPENSE, NET. Interest expense, net, decreased $0.5 million, or
15.6%, from $3.2 million for the year ended December 31, 1995 to $2.7 million
for the year ended December 31, 1996. The decrease is attributable to an
approximately 50 basis point decrease in the average floorplan interest rate as
well as to improved inventory management.
 
  YEAR ENDED DECEMBER 31, 1995 COMPARED TO YEAR ENDED DECEMBER 31, 1994
 
     REVENUES. Revenues increased $41.6 million, or 23.5%, from $177.3 million
for the year ended December 31, 1994 to $218.9 million for the year ended
December 31, 1995. New vehicle sales increased $20.4 million, or 19.4%, from
$105.4 million for the year ended December 31, 1994 to $125.8 million for the
year ended December 31, 1995. The increase is primarily attributable to
successful marketing efforts and continued strong customer support of Toyota
products. Used vehicle sales increased $18.4 million, or 36.9%, from $49.9
million for the year ended December 31, 1994 to $68.3 million for the year ended
December 31, 1995. This increase is primarily attributable to successful
marketing efforts. Parts and service sales increased $1.5 million, or 8.4%, from
$17.9 million for the year

<PAGE>   47
 
ended December 31, 1994 to $19.4 million for the year ended December 31, 1995.
The increase is attributable to continued steady growth driven by increased
vehicle sales. Other dealership revenues increased $1.2 million or 29.3% from
$4.1 million for the year ended December 31, 1994 to $5.3 million for the year
ended December 31, 1995. The increase is due primarily to an increase in the
number of retail new and used vehicle sales.
 
     GROSS PROFIT. Gross profit increased $5.5 million, or 22.3% from $24.7
million for the year ended December 31, 1994 to $30.2 million for the year ended
December 31, 1995. The increase is attributable to increased sales, net of a
minor decline in gross margin from 14.0% for the year ended December 31, 1994 to
13.8% for the year ended December 31, 1995. The slight decline in gross margin
is primarily due to an increase in used vehicle revenues as a percentage of
total revenues.
 
     SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Selling, general and
administrative expenses increased $5.3 million, or 23.6%, from $22.5 million for
the year ended December 31, 1994 to $27.8 million for the year ended December
31, 1995. The increase is primarily attributable to variable incentive pay to
employees and increased marketing expense, both of which are related to the
increase in revenues. Selling, general and administrative expenses, as a
percentage of revenues, remained constant at 12.7% for the year ended December
31, 1994 and for the year ended December 31, 1995.
 
     INTEREST EXPENSE, NET. Interest expense, net, increased $0.7 million, or
28.0%, from $2.5 million for the year ended December 31, 1994 to $3.2 million
for the year ended December 31, 1995. The increase is attributable primarily to
an approximately 170 basis point increase in the floorplan interest rate.

  CASH FLOWS
 
     Total cash and cash equivalents at June 30, 1997, were $10.4 million.
 
     For the three years ended December 31, 1996, the McCall Group generated
$0.8 million in cash flow from net income plus depreciation and amortization.
Net cash flow from operating activities declined from $2.6 million for the year
ended December 31, 1995 to $(5.4) million for the year ended December 31, 1996.
The decline is due primarily to the usage of funds by the McCall Group to pay
down floorplan notes payable and increase inventories. These funds plus other
working capital were primarily invested in inventory to support the McCall
Group's significant growth.
 
     For the six months ended June 30, 1997, the McCall Group generated net cash
flow of $1.2 million from net income plus depreciation and amortization. Floor
plan notes payable paydowns resulted in the net use of cash by operating
activities.
 
                                       47
<PAGE>   48
 
     The change in net cash used in investing activities for the three years
ended December 31, 1996, was primarily attributable to purchases of property and
equipment for the Lexus franchise's new collision service center added in 1995
and showroom expansions at both franchises during 1996.
 
     The change in net cash used in investing activities for the six months
ended June 30, 1997, was primarily attributable to purchases of property and
equipment for the Toyota franchise's used vehicle showroom expansion.
 
     The change in net cash related to financing activities was primarily
attributable to changes in long term debt and cash flows provided by payments on
subscriptions receivable and issuance of common stock.
 
  FLOORPLAN FINANCING
 
     The McCall Group currently obtains floorplan financing for its vehicle
inventory primarily through Toyota Motor Credit Corporation. As of June 30,
1997, the McCall Group had approximately $20.2 million of outstanding floorplan
financing. The debt bears interest at rates ranging from prime minus 75 basis
points to prime minus 100 basis points. Interest expense on floorplan notes
payable, before manufacturer interest assistance, totaled approximately $2.4
million, $3.1 million and $2.5 million for the years ended December 31, 1994,
1995 and 1996, respectively. Manufacturer interest assistance, which is recorded
as a reduction to interest expense, totaled approximately $82,000, $91,000 and
$136,000 for the years ended December 31, 1994, 1995 and 1996, respectively.
 
  LEASES
 
     The McCall Group leases various real estate, facilities and equipment under
operating lease agreements, including leases with related parties. In connection
with the Acquisitions, the McCall Group intends to replace certain existing
leases with leases that have terms of 30 years and will be cancellable at the
Combined Company's option ten years from execution of the lease and at the end
of each subsequent five year period. Such leases initially will have the same
rent as the existing leases and will be subject to increases every five years
based on a percentage of the Consumer Price Index. See "Certain
Transactions -- Leases". Future minimum lease payments for existing operating
leases are as follows: $2.3 million in 1997, $2.2 million in 1998, $2.1 million
in 1999, $2.0 million in 2000 and $1.4 million in 2001.
 
  OTHER
 
     The McCall Group is required to buy certain retail loans from a third party
lender if the loans become delinquent. These loans are due from individuals who
have difficulty obtaining financing and may not have otherwise been able to
secure other financing to purchase a vehicle. These loans carry an interest rate
of prime plus approximately 9% and are secured by the vehicle sold to the
individual. As of June 30, 1997, the aggregate balance of these loans was
approximately $10.2 million. The McCall Group had charge-offs relating to these
loans of $200,000, $232,000, and $539,000 for the years ending December 31,
1994, 1995 and 1996, respectively. The increase in charge-offs during 1996 and
the additions to the reserve for guaranteed loan losses during 1996 are directly
attributable to the increase in loans guaranteed by the McCall Group from 1994
through 1996. The McCall Group sold approximately $3.5 million, $4.5 million and
$7.5 million of full recourse loans to the lender for the years ended December
31, 1994, 1995 and 1996, and had guaranteed loans outstanding of $7.4 million
and $10.4 million at December 31, 1995 and 1996, respectively. Due to the
increase in the number of loans outstanding during this three year period, the
McCall Group experienced a larger number of charge-offs during 1996 than in
prior years. The McCall Group's loan loss reserve has been determined based on
historical charge-off experience, and has remained relatively flat as a
percentage of guaranteed loans outstanding. Management has reviewed the status
of these loans and, based on current facts and circumstances, does not believe
the above described commitment will significantly impact the Combined Company's
operations or liquidity.
 
                                       48

     The McCall Group had working capital of $2.1 million as of December 31,
1996, excluding the reserve for finance, insurance and service contract
chargebacks and the accumulated LIFO reserve. Historically, the McCall Group has
funded its operations with internally generated cash flows and borrowings from
lenders. While there can be no assurance, based on current facts and
circumstances, management believes it has adequate cash flows and financing
alternatives to fund its current operations.

  SIX MONTHS ENDED JUNE 30, 1997 COMPARED TO SIX MONTHS ENDED JUNE 30, 1996
 
     REVENUES. Revenues increased $19.3 million, or 17.8%, from $108.2 million
for the six months ended June 30, 1996 to $127.5 million for the six months
ended June 30, 1997. New vehicle sales increased $15.8 million, or 26.6%, from
$59.4 million for the six months ended June 30, 1996 to $75.2 million for the
six months ended June 30, 1997. The increase is primarily attributable to the
addition of the new Nissan franchise during 1996 located just north of Austin,
Texas. Additionally, sales at the Smith Group's Nissan franchises were
positively impacted by manufacturer incentive programs. Used vehicle sales
increased $3.1 million, or 9.7%, from $32.1 million for the six months ended
June 30, 1996 to $35.2 million for the six months ended June 30, 1997. The
increase is due primarily to the addition of the new Nissan franchise during
1996, offset by declines at other franchises in the Smith Group. The declines
were caused in large part by the strong new vehicle sales capturing many used
vehicle customers. Parts and service sales increased $0.1 million, or 0.7%, from
$14.0 million for the six months ended June 30, 1996 to $14.1 million for the
six months ended June 30, 1997. The increase is primarily attributable to the
addition of the new Nissan franchise during 1996, while the other franchises
declined slightly from year to year. Other dealership revenue increased $0.4
million or 15.4% from $2.6 million for the six months ended June 30, 1996 to
$3.0 million for the six months ended June 30, 1997. The increase is due
primarily to an increase in the number of retail new and used vehicle sales.

     GROSS PROFIT. Gross profit increased $3.2 million, or 22.4%, from $14.3
million for the six months ended June 30, 1996 to $17.5 million for the six
months ended June 30, 1997. The increase is attributable to increased sales and
an increase in the gross margin from 13.3% for the six months ended June 30,
1996 to 13.8% for the six months ended June 30, 1997. The gross margin was
favorably impacted by manufacturer incentive programs which increased new
vehicle gross margins.
 
     SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Selling general and
administrative expenses increased $2.2 million, or 19.0%, from $11.6 million for
the six months ended June 30, 1996 to $13.8 million for the six months ended
June 30, 1997. The increase is primarily attributable to variable incentive pay
to employees and expenses relating to the new Nissan franchise opened in 1996.
As a percentage of revenues, selling, general and administrative expenses
increased slightly from 10.7% for the six months ended June 30, 1996 to 10.9%
for the six months ended June 30, 1997.
 
     INTEREST EXPENSE, NET. Interest expense, net, increased $0.1 million or
12.5% from $0.8 million for the six months ended June 30, 1996 to $0.9 million
for the six months ended June 30, 1997. The increase is primarily due to the
addition of the new Nissan franchise opened in 1996.
 
  YEAR ENDED DECEMBER 31, 1996 COMPARED TO YEAR ENDED DECEMBER 31, 1995
 
     REVENUES. Revenues decreased $3.0 million, or 1.4%, from $221.3 million for
the year ended December 31, 1995 to $218.3 million for the year ended December
31, 1996. New vehicle sales decreased $8.0 million, or 6.1%, from $132.2 million
for the year ended December 31, 1995 to $124.2 million for the year ended
December 31, 1996. The decrease is primarily attributable to reduced unit sales
at the Smith Group's Dallas Nissan franchise. The sales were impacted by changes
in the franchise's market place and consumer preferences in the region. The
decline was partially offset by revenues generated by a new Nissan franchise
located just north of Austin, Texas, opened in late 1996. Used vehicle sales
increased $3.2 million, or 5.6%, from $57.4 million for the year ended December
31, 1995 to $60.6 million for the year ended December 31, 1996. The increase is
primarily attributable to increased focus on used vehicle sales by the Dallas
Nissan franchise in response to changes in its new vehicle market conditions.
Parts and service sales increased $2.4 million, or 9.2%, from $26.2 million for
the year ended December 31, 1995 to $28.6 million for the year ended December
31, 1996. Other dealership revenues decreased $0.6 million or 10.9% from $5.5
million for the year ended December 31, 1995 to $4.9 million for the year ended
December 31, 1996. The decrease is due primarily to a decline in the number of
retail new vehicle sales, partially offset by an increase in the number of
retail used vehicle sales.
 
     GROSS PROFIT. Gross profit increased by $0.5 million, or 1.8%, from $28.6
million for the year ended December 31, 1995 to $29.1 million for the year ended
December 31, 1996. Gross profit increased, despite decreased sales, due to a
higher gross margin. The gross margin increased as higher margin parts and
service sales increased and became a greater percentage of total revenues. Gross
margin increased from 12.9% for the year ended December 31, 1995 to 13.3% for
the year December 31, 1996.
 
     SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Selling, general and
administrative expenses increased by $0.9 million, or 3.9%, from $22.8 million
for the year ended December 31, 1995 to $23.7 million for the year ended
December 31, 1996. The increase is primarily attributable to marketing expenses
relating to the opening of the Smith Group's new Nissan franchise in Austin,
Texas. As a percentage of total revenues, selling, general and administrative
expenses increased from 10.3% for the year ended December 31, 1995 to 10.8% for
the year ended December 31, 1996.
 
     INTEREST EXPENSE, NET. Interest expense, net, decreased by $1.3 million, or
43.3%, from $3.0 million for the year ended December 31, 1995 to $1.7 million
for the year ended December 31, 1996. The decrease is attributable to an
approximately 50 basis point decrease in the average floorplan interest rate,
increased floorplan assistance payments from the Manufacturers and reduced
average floorplan levels.

  YEAR ENDED DECEMBER 31, 1995 COMPARED TO YEAR ENDED DECEMBER 31, 1994
 
     REVENUES. Revenues increased $4.2 million, or 1.9%, from $217.1 million for
the year ended December 31, 1994 to $221.3 million for the year ended December
31, 1995. New vehicle sales decreased $4.7 million or 3.4% from $136.9 million
for the year ended December 31, 1994 to $132.2 million for the year ended
December 31, 1995. The decline is primarily due to a reduced level of customer
support of the Smith Group's products. Used vehicle sales increased $7.9
million, or 16.0%, from $49.5 million for the year ended December 31, 1994 to
$57.4 million for the year ended December 31, 1995. The increase is primarily
attributable to increased focus on used vehicle sales in response to changes in
the Smith Group's new vehicle market conditions. Parts and service sales
increased $0.7 million, or 2.7%, from $25.5 million for the year ended December
31, 1994 to $26.2 million for the year ended December 31, 1995. The growth is
primarily attributable to continued steady growth driven by overall increased
vehicle sales. Other dealership revenues increased $0.4 million or 7.8% from
$5.1 million for the year ended December 31, 1994 to $5.5 million for the year
ended December 31, 1995. The increase is due primarily to an increase in the
number of retail used vehicle sales, partially offset by a decline in the number
of retail new vehicle sales.
 
     GROSS PROFIT. Gross profit increased $1.4 million, or 5.1%, from $27.2
million for the year ended December 31, 1994 to $28.6 million for the year ended
December 31, 1995. The increase is attributable to increased revenues and
improved gross margin, as higher margin parts and service sales increased and
became a greater percentage of total revenues. Gross margin increased from 12.5%
for the year ended December 31, 1994 to 12.9% for the year ended December 31,
1995.
 
     SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Selling, general and
administrative expenses increased $1.1 million, or 5.1% from $21.7 million for
the year ended December 31, 1994 to $22.8 million for the year ended December
31, 1995. As a percentage of revenues, selling, general and administrative
expenses increased from 10.0% for the year ended December 31, 1994 to 10.3% for
the year ended December 31, 1995.
 
     INTEREST EXPENSE, NET. Interest expense, net, increased $0.9 million, or
42.9%, from $2.1 million for the year ended December 31, 1994 to $3.0 million
for the year ended December 31, 1995. The increase is primarily attributable to
an approximately 170 basis point increase in the average floorplan interest
rate.

</TABLE>
 
  CASH FLOWS
 
     Total cash and cash equivalents at June 30, 1997, were $9.4 million.
 
     For the three year period ended December 31, 1996, the Smith Group
generated $10.7 million in net cash from operating activities, primarily from
net income plus depreciation and amortization.
 
                                       51
<PAGE>   52
 
     Net cash from operating activities decreased from $2.4 million for the six
months ended June 30, 1996 to $2.1 million for the six months ended June 30,
1997, as cash generated by increased net income for the six months ended June
30, 1997 of $0.6 million and changes in inventories and floorplan financing were
offset by changes in accounts payable and accrued liabilities and accounts
receivable.
 
     The change in net cash used in investing activities was primarily
attributable to purchases of property and equipment relating to the new Nissan
franchise in Austin, Texas and various facility improvements and computer
equipment purchases at the other Smith Group franchises.
 
     The change in net cash used in financing activities was primarily
attributable to net borrowings and repayments of debt and distributions to the
stockholders.
 
  FLOORPLAN FINANCING
 
     The Smith Group currently obtains floorplan financing for its vehicle
inventory through Ford Motor Credit Company, NationsBank and Nissan Motor
Acceptance Corporation. As of June 30, 1997, the Smith Group had approximately
$33.5 million of floorplan indebtedness outstanding. The debt bears interest at
rates ranging from prime to prime plus 175 basis points for new and used
vehicles. Interest expense on floorplan notes payable, before manufacturer
interest assistance, totaled approximately $2.2 million, $3.2 million and $2.5
million for the years ended December 31, 1994, 1995 and 1996, respectively.
Manufacturer interest assistance, which is recorded as a reduction to interest
expense, totaled approximately $0.7 million, $0.8 million and $1.1 million for
the years ended December 31, 1994, 1995 and 1996, respectively. Payments on the
notes are due when the related vehicles are sold and are collateralized by
substantially all new and used vehicles.
 
  LEASES
 
     The Smith Group leases various facilities and equipment under operating
lease agreements, including leases with related parties. Certain of these leases
are noncancelable and expire on various dates through August 2013. These lease
agreements are subject to renewal under essentially the same terms and
conditions as the original leases. In connection with the Acquisitions, the
Smith Group intends to replace certain existing leases with leases that will
have terms of 30 years and will be cancellable at the Combined Company's option
ten years from execution of the lease and at the end of each subsequent five
year period. Such leases initially will have the same rent as the existing
leases and will be subject to increases every five years based on a percentage
of the Consumer Price Index. See "Certain Transactions -- Leases". Future
minimum lease payments for existing operating leases are as follows: $1.4
million in 1997, $1.4 million in 1998, $1.4 million in 1999, $1.0 million in
2000 and $0.8 million in 2001.
 
  OTHER
 
     The Smith Group had working capital of $8.1 million as of December 31,
1996, adjusted for the accumulated LIFO reserves. Historically, the Smith Group
has funded its operations with internally generated cash flow and borrowings
from lenders. While there can be no assurance, based on current facts and
circumstances, management believes it has adequate cash flows and financing
alternatives to fund its current operations.
 
CYCLICALITY
 
     The Combined Company's operations, like the automotive retailing industry
in general, can be impacted by a number of factors relating to general economic
conditions, including consumer business cycles, consumer confidence, economic
conditions, availability of consumer credit and interest rates. Although the
above factors, among others, may impact the Combined Company's business, Group 1
Automotive believes the impact on the Combined Company's operations of future
negative trends in such factors will be somewhat mitigated by its (i) strong
parts, service and collision repair services, (ii) variable cost salary
structure, (iii) geographic diversity, and (iv) product diversity.
 
                                       52
<PAGE>   53
 
SEASONALITY
 
     The Combined Company's operations will be subject to seasonal variations,
with the second and third quarters generally contributing more operating profit
than the first and fourth quarters. This seasonality is driven by three primary
forces: (i) Manufacturer-related factors, primarily the historical timing of
major manufacturer incentive programs and model changeovers, (ii)
weather-related factors, which primarily affect parts and service and (iii)
consumer buying patterns.
 
EFFECTS OF INFLATION
 
     Due to the relatively low levels of inflation experienced in fiscal 1994,
1995 and 1996 and the six months of 1997, inflation did not have a significant
effect on the results of the combined Founding Groups during those periods.
 
FORWARD-LOOKING STATEMENTS
 
     Certain statements contained herein are not based on historical facts, but
are forward-looking statements that are based upon numerous assumptions about
future conditions that could prove not to be accurate. Such forward-looking
statements include, without limitation, the statements regarding the trends in
the industry set forth in the Prospectus Summary and under the caption
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" regarding the Combined Company's anticipated future financial
results and position. Although Group 1 Automotive believes that the expectations
reflected in such forward-looking statements are reasonable, it can give no
assurance that such expectations will prove to have been correct. Important
factors that could cause actual results to differ materially from Group 1
Automotive's expectations are disclosed in this Prospectus, including but not
limited to the matters described in "Risk Factors".

GENERAL
 
     COMBINED COMPANY
 
     Group 1 Automotive was founded to become a leading operator and
consolidator in the highly fragmented automotive retailing industry and has
conducted no operations to date. Immediately prior to the closing of the
Offering, Group 1 Automotive will acquire the Founding Groups. Upon consummation
of the Acquisitions, the Combined Company will own 30 automobile dealerships and
five collision service centers located in Texas and Oklahoma, and will sell new
and used cars and light trucks, provide maintenance and repair services, sell
replacement parts and provide related financing, insurance and extended service
contracts. The Combined Company will represent 21 American and Asian brands
operating two Acura, one Chevrolet, one Chrysler, one Dodge, one Eagle, two GMC,
three Honda, two Isuzu, one Jeep, one Kia, one Lexus, one Lincoln, one Mazda,
one Mercury, two Mitsubishi, three Nissan, one Oldsmobile, one Plymouth, one
Pontiac, one Suzuki and two Toyota dealerships. The Combined Company's
dealerships will include the second-largest Toyota dealership in the United
States as measured by 1996 new retail unit sales and one of the largest
dealership groups in Oklahoma.
 
     The principals of the Founding Groups have over 90 years of combined
experience in the automotive retailing industry with family ownership dating
back as far as 1917. In addition, the principals of the Founding Groups have
been recognized as leaders in the automotive retailing industry, serving at
various times in leadership positions in state and national industry
organizations. The Founding Groups' dealerships have also received numerous
awards based on various performance measures. The principals of the Founding
Groups will continue to manage their businesses and play a significant role in
the Combined Company's operating and acquisition strategies.
 
     Group 1 Automotive believes that the Combined Company's structural,
managerial and operational strengths will include (i) brand and geographic
diversity; (ii) the ability to capitalize on regional economies of scale; (iii)
cost savings derived from nationally centralized financing and administrative
functions; (iv) the experience of the Combined Company's senior management in
successfully consolidating and operating in highly fragmented industries; (v)
the reputations, experience and performance of the Founding Groups' management
and principals as leaders in the automotive retailing industry; (vi) the
established customer base and local name recognition of the Founding Groups'
dealerships; (vii) the Founding Groups' proven ability to source high quality
used vehicles cost-effectively through trade-ins and off-lease programs; and
(viii) access to equity incentives to attract and retain high quality personnel.
 
     The Combined Company will pursue a growth strategy led by a management team
with extensive experience in consolidation and the management of growth
companies. B.B. Hollingsworth, Jr., Chairman of the Board, President and Chief
Executive Officer of the Combined Company, has experience not only in the
automotive retailing industry, but also in consolidating a major national
industry, having served in various senior management capacities, including
President, of Service Corporation International during its early growth period
as the world's leading consolidator of the funeral industry. In addition, John
T. Turner, Senior Vice President -- Corporate Development, has been actively
involved in the acquisition efforts of Service Corporation International serving
under Mr. Hollingsworth as Senior Vice President -- Corporate Development and
serving more recently as Managing Director -- Corporate Development, Europe. See
"Management".

Houston, Texas.
 
     SMITH GROUP. The Smith Group consists of one Acura dealership in Houston,
Texas, Honda, GMC, Oldsmobile, Mitsubishi, Lincoln, Mercury and Kia dealerships
in Beaumont, Texas, a Nissan dealership in Richardson, Texas (a suburb of
Dallas) and two Nissan dealerships, one Mitsubishi dealership and one Suzuki
dealership in the Austin, Texas area. The Smith family has been in the
automotive retailing business since 1917.
 
     KINGWOOD GROUP. The Kingwood Group consists of one Honda and one Isuzu
dealership in Kingwood, Texas, a suburb of Houston. The Honda dealership was
established in 1989 and the Isuzu dealership was established in 1996. Mr.
Hollingsworth and John H. Duncan, a director of the Combined Company, own
interests in these dealerships.
 
ACQUISITIONS AND MANUFACTURER AWARDED DEALERSHIP
 
     The Founding Groups have a history of successfully acquiring and
integrating dealerships. Since 1994 the Founding Groups have acquired four
dealerships and were awarded one new franchise by a Manufacturer. For the year
ended December 31, 1996, these dealerships represented $63.8 million in total
revenues, two of which had only part year revenues in 1996. The Howard Group
acquired a Honda and an Acura dealership in 1994 and a Dodge dealership in 1996;
all of which are located in Oklahoma City. The Smith Group was awarded a new
Nissan franchise in Austin, Texas in December 1996. The Kingwood Group acquired
an Isuzu dealership in Houston, Texas in late 1996.
 
INDUSTRY OVERVIEW
 
     With more than $600 billion in 1996 sales, automotive retailing is the
largest retail trade sector in the United States. The industry is highly
fragmented and largely privately held with approximately 22,000 automobile
dealership locations representing more than 53,000 franchised dealerships. In
1996, U.S. franchised automobile dealers sold 15.1 million new vehicles and 19.2
million used vehicles for sales of approximately $328.4 billion and $171.8
billion, respectively. It is estimated that sales by franchised automobile
dealers account for one-fifth of the nation's total retail sales of all products
and merchandise. Since 1992, new vehicle revenues have grown at a 10.5% compound
annual rate. Over the same period,
 
                                       55
<PAGE>   56
 
used vehicle revenues have grown at a 14.6% compound annual rate. Slower unit
volume growth over this time period has been offset by the rising prices
associated with new vehicles and, on average, the higher prices paid for later
model high quality used vehicles which now comprise a significant part of the
used vehicle market. Automobile sales are affected by many factors, including
rates of employment, income growth, interest rates, weather patterns and other
national and local economic conditions, automotive innovations and general
consumer sentiment. See "Risk Factors -- Cyclicality" and "Risk
Factors -- Seasonality".
 
     The following table sets forth new and used vehicle sales by franchised
automobile dealers in the United States for each of the five years ended
December 31, 1996. New vehicles can only be sold at retail by franchised
dealerships. The following table excludes sales of used vehicles by
nonfranchised dealerships and casual sales by individuals. Nonfranchised
dealerships and individuals had aggregate sales of $117.3 billion, $133.2
billion, $173.8 billion, $181.3 billion and $172.4 billion, respectively, for
each of the five years ended December 31, 1996.

     Manufacturers originally established franchised dealer networks for the
distribution of their vehicles as single-dealership, single-owner operations. In
return for distribution rights within specified territories, Manufacturers
exerted significant influence over such matters as a dealer's location,
inventory size and composition and merchandising programs, as well as the
identity of owners and managers. This strict control contributed to the
proliferation of small dealerships, which at their peak in the late 1940s
numbered in excess of 46,000 dealership locations. Several manufacturers went
out of business in the 1950s, and the number of dealership locations decreased
to 36,000 by 1960.
 
     Significant industry changes took place in the 1970s when fuel shortages
forced dramatic increases in gasoline prices and foreign manufacturers increased
their penetration of the U.S. market with fuel-efficient, low-cost vehicles. As
a result of these competitive pressures, dealers were able to negotiate
significant changes in the traditional distribution system with manufacturers.
Dealers began to add foreign franchises and the phenomenon of the
multi-franchise automobile dealer, or megadealer, emerged, prompting the
significant acquisition and consolidation activities of the 1980s. The easing of
restrictions against megadealers, competitive pressures upon undercapitalized
dealerships and the aging of dealership owners has led to further consolidation
of the industry. Since 1960, the number of dealership locations has declined 39%
to the current 22,000 level.
 
     As the industry has evolved, so has the dealership profile. Over the past
three decades, there has been a trend toward fewer, but larger, dealerships. In
1996, each of the largest 100 dealer groups had more than $200 million in
revenues. Although significant consolidation has taken place since its
inception, the industry today remains highly fragmented, with the largest 100
dealer groups generating less than 10% of total sales revenues and controlling
approximately 5% of all franchised dealerships. Group 1 Automotive believes that
these factors, together with increasing capital requirements for operating
automobile dealerships, lack of a viable exit strategy (especially for larger
dealerships) and the aging of dealership owners provide an attractive
environment for the Combined Company's consolidation opportunities.
 
     As with retailers generally, automobile dealership profitability varies
widely and depends in part on the effective management of inventory, marketing,
quality control and responsiveness to customers.

Since 1991, retail automobile dealerships in the United States have earned on
average between 12.9% and 14.1% total gross margin on sales with smaller
dealerships generally realizing a higher gross margin than larger dealerships.
New vehicle sales were the smallest proportionate contributors to dealers' gross
profits during this period, most recently earning an average gross margin of
6.5% in 1996. Used vehicles provided higher gross margins than new vehicles
during this period, with an average used vehicle gross margin of 11.0% in 1996.
Dealerships also offer a range of other services and products, including repair
and warranty work, replacement parts, extended service contracts, financing and
credit insurance.
 
BUSINESS STRATEGY
 
     Group 1 Automotive plans to achieve its goal of becoming a leading
consolidator, while maintaining its high operating standards in the automotive
retailing industry, by (i) emphasizing growth through acquisitions and (ii)
implementing an operating strategy that focuses on decentralized dealership
operations, nationally centralized administrative functions, the expansion of
higher margin businesses, a commitment to customer service and the
implementation of new technology initiatives. By complementing the Founding
Groups' industry leaders, management talent and proven operating capabilities
with a corporate management team which is experienced in achieving and managing
long-term growth in a consolidation environment, Group 1 Automotive believes
that the Combined Company will be in a strong position to execute this strategy.
 
     GROWTH THROUGH ACQUISITIONS
 
     Group 1 Automotive intends to implement an aggressive, yet disciplined,
acquisition program by pursuing (i) large, profitable and well managed
"platform" acquisitions in large metropolitan and high-growth suburban
geographic markets that the Founding Groups do not currently serve and (ii)
smaller "add-on" acquisitions that will allow the Combined Company to increase
brand diversity, capitalize on regional economies of scale and offer a greater
breadth of products and services in each of the markets in which it operates. In
this regard, Group 1 Automotive has negotiated and executed an arrangement
letter with Chase Securities Inc. and Comerica Bank for a $125 million Credit
Facility, of which a portion will be used, in combination with the Combined
Company's common stock, for acquisitions. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations -- Combined Founding
Groups' Commitments -- Credit Facility".
 
     ENTERING NEW GEOGRAPHIC MARKETS. Group 1 Automotive intends to expand into
geographic markets it does not currently serve by acquiring large, profitable
and well established megadealers that, like the Founding Groups, are leaders in
their regional markets. The Combined Company will target new platform
megadealers having superior operational and financial management personnel which
the Combined Company will seek to retain. Group 1 Automotive believes that the
retention of existing high quality management will enable acquired megadealers
to continue to operate effectively with management personnel who understand the
local market while allowing the Combined Company to source future acquisitions
more effectively and expand its operations without having to employ and train
untested new personnel. Moreover, Group 1 Automotive believes that the Combined
Company will be well positioned to pursue larger, well established acquisition
candidates as a result of its depth of management, the Combined Company's
capital structure and the reputation of the principals of the Founding Groups as
leaders in the automotive retailing industry.
 
     EXPANDING WITHIN EXISTING MARKETS. Group 1 Automotive plans to acquire
additional dealerships in each of the markets in which it operates, including
acquisitions that increase the brands, products or services offered in that
market. Group 1 Automotive believes that these acquisitions will facilitate the
Combined Company's operating efficiencies and cost savings on a regional level
in areas such as facility and personnel utilization, vendor consolidation and
advertising. Group 1 Automotive has recently entered into definitive agreements
to acquire, subject to manufacturer approval and a due diligence investigation,
two dealership locations consisting of Acura, Buick, Dodge, Ford, Mercedes-Benz,
Nissan and Volvo dealerships in Texas for aggregate payments of $9.0 million in
cash. These two acquisitions, if
 
                                       57
<PAGE>   58
 
consummated, would also require the Combined Company to incur approximately
$13.0 million of floorplan indebtedness in connection with the purchase of
vehicle inventories of the dealerships.
 
     MANUFACTURERS' LIMITATIONS ON ACQUISITIONS. The Combined Company's
acquisition program may be limited to some extent by the Manufacturers. Under
the limitations currently imposed by the Manufacturers, the Combined Company
could acquire no more than five additional Toyota dealerships, two additional
Lexus dealerships, four additional Honda dealerships, one additional Acura
dealership, approximately 400 additional Ford and Lincoln Mercury dealerships
and 10 additional GM dealership locations (within the next two years, subject to
being increased). The Combined Company, upon consummation of the Acquisitions,
will own, two Toyota, one Lexus, three Honda, two Acura, one Lincoln and one
Mercury franchise and three GM dealership locations. The other Manufacturers,
which have no such limitations, accounted for the following approximate number
of dealerships in the United States, as of December 31, 1996: Chrysler
Corporation, 13,000 (at 4,600 locations); Nissan, 1,200; Mitsubishi, 500; Isuzu,
500; Suzuki, 300; and Kia, 200. However, not all of these existing dealership
locations and franchises may be eligible for acquisition. In addition, all of
the Manufacturers, whether or not they have numerical limitations on the number
of dealerships that may be acquired, will require the Combined Company to obtain
the consent of the applicable Manufacturer prior to the acquisition of any
dealership franchises of such Manufacturer, and may withhold such consents based
on other considerations, such as the failure of existing dealerships to comply
with their franchise agreements or to meet required CSI scores, or the ownership
by the Combined Company of dealerships of competing Manufacturers. Also, as a
condition to granting its consent to the transfer of the 3 Honda and 2 Acura
dealerships to be acquired by Group 1 Automotive pursuant to the Acquisitions,
American Honda has imposed additional restrictions on the Combined Company,
including a requirement that more than 50% of the outstanding Common Stock of
the Combined Company be owned at all times by persons approved by American
Honda, restrictions on transfers of the shares of Common Stock acquired by the
stockholders of the Founding Companies pursuant to the Acquisitions, and the
requirement that American Honda approve the ownership by any stockholder of 5%
or more of the Common Stock of the Combined Company (other than certain
institutional investors, which may own up to 10%, as well as any future public
offering of Common Stock of the Combined Company. All of the foregoing could
have the effect of limiting the Combined Company's ability to implement its
acquisition program. In addition, American Honda's policy on public ownership of
Honda and Acura dealerships requires that individuals or entities that acquire,
own or control more than 5% of the Common Stock of the Combined Company must
provide American Honda with copies of all filings made to the Securities and
Exchange Commission, all comparable filings made to state agencies and annual
audited financial statements. See "Risk Factors -- Manufacturers' Control over
Dealerships", "Risk Factors -- Restrictions Imposed by Agreement with American
Honda Motor Co., Inc.", "Risk Factors -- Risks Relating to Failure to Meet
Manufacturer CSI Scores" and "Risk Factors -- Dependence on Acquisitions for
Growth; Manufacturers' Restrictions on Acquisitions".
 
     Of the approximately 15 million new vehicles sold in the United States in
1996, approximately 31.3% were manufactured by GM, 25.4% were manufactured by
Ford Motor, 16.2% were manufactured by Chrysler Corporation, 7.7% were
manufactured by Toyota Motor, 5.6% were manufactured by Honda Motor, 5.0% were
manufactured by Nissan Motor and 8.8% were manufactured by other manufacturers.
 
     OPERATING STRATEGY
 
     Group 1 Automotive intends to implement an operations strategy that focuses
on decentralized dealership operations, nationally centralized administrative
functions, expansion of higher margin businesses, commitment to customer service
and new technology initiatives.
 
     Group 1 Automotive has formed an operations committee comprised of the
chief operating officers of the Founding Groups and the general managers of the
dealerships in order to identify and share best practices. Group 1 Automotive
intends to incorporate the key officers and management of the Combined Company's
future acquisitions into this operations committee. Group 1 Automotive believes
that this operations committee will promote the widespread application of the
Combined Company's broad
 
                                       58
<PAGE>   59
 
strategic initiatives, facilitate the integration of the Founding Groups and
future acquisitions and improve operating efficiency and overall customer
satisfaction.
 
     DECENTRALIZED DEALERSHIP OPERATIONS. Group 1 Automotive believes that
decentralizing the Combined Company's dealership operations on a regional, or
platform, basis will enable it to provide superior customer service and a
focused, market-specific responsiveness to sales, service, marketing and
inventory control. Local presence and an in-depth knowledge of customers' needs
and preferences are important in generating internally-driven market share
growth. By coordinating certain operations on a platform basis, Group 1
Automotive believes that the Combined Company will achieve cost savings in such
areas as vendor consolidation, facility and personnel utilization and
advertising. Group 1 Automotive intends to create incentives for the Combined
Company's entrepreneurial management teams and sales forces at the regional
level through the use of stock options and/or cash bonus programs.
 
     NATIONALLY CENTRALIZED ADMINISTRATIVE FUNCTIONS. The consolidation of
purchasing power on a centralized basis in the area of financing should result
in significant cost savings. For example, in connection with the Offering, all
of the Combined Company's floorplan financing will benefit from interest rate
reductions. Rate reductions have already become effective with respect to
approximately 75% of the Founding Groups' floorplan debt. The current reductions
range between 25 and 225 basis points. Additionally, the Combined Company's
Credit Facility, once closed, will result in further rate reductions. Subsequent
to the Offering, the Combined Company intends to refinance approximately $50
million in floorplan financing with the Credit Facility. The impact of these
changes is expected to reduce the Combined Company's annual interest expense by
more than $1.0 million. Furthermore, Group 1 Automotive expects that significant
cost savings for the Combined Company can be achieved through the consolidation
of administrative functions such as risk management, employee benefits and
employee training. For example, Group 1 Automotive has negotiated insurance
coverage that is expected to result in annual cost savings to the Combined
Company of approximately 25 to 30 percent.
 
     EXPAND HIGHER MARGIN ACTIVITIES. The Combined Company will focus on
expanding higher margin businesses such as used vehicle retail sales, service
and parts and finance and insurance. While each of the Combined Company's
platforms will be able to operate independently in a manner consistent with its
specific market's characteristics, each platform will pursue an integrated
strategy to grow each of these higher margin businesses to enhance profitability
and stimulate internal growth. With a competitive advantage in sourcing, the
ability to provide manufacturer-backed extended service contracts, and
attractive lease financing, new vehicle franchises are especially well
positioned to capitalize on industry growth in used vehicle sales. In addition,
each of the Combined Company's dealerships will offer an integrated service and
parts department, which will provide an important source of recurring higher
margin revenues. The Combined Company also will have the opportunity on each new
or used vehicle sold to generate incremental revenues from the sale of extended
service contracts, credit insurance policies and finance and lease contracts.
Each of these business areas will be a focus of internal growth.
 
     COMMITMENT TO CUSTOMER SERVICE. The Combined Company will be focused on
providing a high level of customer service to meet the needs of an increasingly
sophisticated and demanding automotive consumer. The Combined Company will
strive to cultivate lasting relationships with its customers, which it believes
enhances the opportunity for significant repeat and referral business. For
example, the Founding Groups regard their service and repair activities as an
integral part of their overall approach to customer service, providing an
opportunity to foster ongoing relationships with the Combined Company's
customers and deepen customer loyalty. The Combined Company's dealerships will
continuously review their selling processes in their effort to satisfy their
customers.
 
DEALERSHIP OPERATIONS
 
     Each of the Founding Groups has established a management structure that
promotes and rewards entrepreneurial spirit, individual pride and responsibility
and the achievement of team goals. The general manager of each Founding Group
dealership is ultimately responsible for the operation, personnel and financial
performance of the dealership. The general manager is complemented with a
management team
 
                                       59
<PAGE>   60
 
consisting of a new vehicle sales manager, used vehicle sales manager, service
and parts managers and finance managers. Each dealership is operated as a
distinct profit center, in which dealership general managers are given a high
degree of autonomy. The general manager and the other members of the dealership
management team, as long-time members of their local communities, are typically
best able to judge how to conduct day-to-day operations based on the team's
experience in and familiarity with its local market.
 
     Each of the Founding Groups' dealerships engage in a number of
inter-related businesses: new vehicle sales; used vehicle sales; service and
parts operations; and finance and insurance.
 
  NEW VEHICLE SALES
 
     The Founding Groups represent 21 American and Asian brands of economy,
family, sports and luxury cars and light trucks and sport utility vehicles. The
following table sets forth for 1996, certain information relating to the brands
of new vehicles sold at retail by the Founding Groups:

     The Founding Groups' new vehicle retail sales include traditional new
vehicle retail lease transactions and lease-type transactions, both of which are
arranged by the Founding Groups. New vehicle leases generally have short terms,
which brings the consumer back to the market sooner than if the purchase were
debt financed. In addition, leases provide the Founding Groups with a steady
source of late-model, off-lease vehicles for its used vehicle inventory.
Generally, leased vehicles remain under factory warranty for the term of the
lease, which allows the Founding Groups to provide repair service to the lessee
throughout the lease term.
 
     The Founding Groups seek to provide customer-oriented service designed to
meet the needs of its customers and establish lasting relationships that will
result in repeat and referral business. For example, the Founding Groups'
dealerships strive to: (i) employ more efficient selling approaches; (ii)
utilize
 
                                       60
<PAGE>   61
 
computer technology that decreases the time necessary to purchase a vehicle;
(iii) engage in extensive follow-up after a sale in order to develop long-term
relationships with customers; and (iv) extensively train their sales staffs to
be able to meet the needs of the customer. The Founding Groups continually
evaluate innovative ways to improve the buying experience for its customers and
believes that its ability to share best practices among its dealerships gives it
an advantage over smaller dealerships.
 
     The Founding Groups acquire substantially all their new vehicle inventory
from Manufacturers. Manufacturers allocate a limited inventory among their
franchised dealers based primarily on sales volume and input from dealers. The
Founding Groups finance their inventory purchases through revolving credit
arrangements known in the industry as floorplan facilities.
 
  USED VEHICLE SALES
 
     The Founding Groups sell used vehicles at each of their franchised
dealerships. Sales of used vehicles have become an increasingly significant
source of profit for the Founding Groups. Consumer demand for used vehicles has
increased as prices of new vehicles have risen and as more high quality used
vehicles have become available. Furthermore, used vehicles typically generate
higher gross margins than new vehicles because of their limited comparability
and the somewhat subjective nature of their valuation. The Founding Groups
intend to continue growing its used vehicle sales operations by maintaining a
high quality inventory, providing competitive prices and extended service
contracts for its used vehicles and continuing to promote used vehicle sales.
 
     Profits from sales of used vehicles are dependent primarily on the ability
of the Founding Groups' dealerships to obtain a high quality supply of used
vehicles and effectively manage that inventory. The Founding Groups' new vehicle
operations provide the Founding Groups' used vehicle operations with a large
supply of high quality trade-ins and off-lease vehicles, which are the best
sources of high quality used vehicles. The Founding Groups supplement their used
vehicle inventory with used vehicles purchased at auctions.
 
     Each of the Founding Groups generally maintains a 45 to 60 day supply of
used vehicles and offers to other dealers and wholesalers used vehicles that the
Founding Groups do not retail to customers. Trade-ins may be transferred among
dealerships to provide balanced inventories of used vehicles at each of the
Founding Groups' dealerships. Group 1 Automotive believes that the Acquisitions
and acquisitions of additional dealerships will expand the internal market for
transfers of used vehicles among the Combined Company's dealerships and,
therefore, increase the ability of each of the Combined Company's dealerships to
offer the same brand of used vehicles as it sells new and to maintain a balanced
inventory of used vehicles. Group 1 Automotive intends to develop integrated
computer inventory systems that will allow it to coordinate vehicle transfers
between the Combined Company's dealerships, primarily on a regional basis.
 
     The Founding Groups have taken several steps towards building client
confidence in their used vehicle inventory, one of which includes their
participation in the Manufacturers' certification processes which are available
only to new vehicle franchises. This process makes these used vehicles eligible
for new vehicle benefits such as new vehicle finance rates and extended
Manufacturer warranties. In addition, each of the Founding Groups' dealerships
offer extended warranties covering the used vehicles that each of its
dealerships sells.
 
     Group 1 Automotive believes that franchised dealership strengths in
offering used vehicles include: (i) access to trade-ins on new vehicle
purchases, which are typically lower mileage and higher quality relative to
trade-ins on used car purchases, (ii) access to late-model, low mileage
off-lease vehicles, and (iii) the availability of Manufacturer certification and
extended Manufacturer warranties for the Founding Groups' higher quality used
vehicles. This supply of high quality trade-ins and off-lease vehicles reduces
the Founding Groups' dependence on auction vehicles, which are typically a
higher cost source of used vehicles.

  PARTS AND SERVICE
 
     The Founding Groups provide parts and service at each of their franchised
dealerships primarily for the vehicle makes sold by their dealerships. The
Founding Groups provide their maintenance and repair services at a combined 30
dealerships and five collision service centers, utilizing approximately 500
service bays in providing these services. The Founding Groups perform both
warranty and non-warranty service work.
 
     Historically, the automotive repair industry has been highly fragmented.
However, Group 1 Automotive believes that the increased use of advanced
technology in vehicles has made it difficult for independent repair shops to
retain the expertise to perform major or technical repairs. Additionally,
Manufacturers permit warranty work to be performed only at franchised
dealerships. Hence, unlike independent service stations, or independent and
superstore used car dealerships with service operations, the Founding Groups'
franchised dealerships are qualified to perform work covered by Manufacturer
warranties. Given the increasing technological complexity of motor vehicles and
the trend toward extended manufacturer and dealer warranty periods for new
vehicles, Group 1 Automotive believes that an increasing percentage of repair
work will be performed at the Founding Groups' franchised dealerships, each of
which have the sophisticated equipment and skilled personnel necessary to
perform such repairs and offer extended service contracts.
 
     The Founding Groups attribute their profitability in parts and service to a
comprehensive management system, including the use of variable rate pricing
structures, cultivation of strong client relationships through an emphasis on
preventive maintenance and the efficient management of parts inventory.
 
     In charging for their mechanics' labor, the Founding Groups use variable
rate structures designed to reflect the difficulty and sophistication of
different types of repairs. The percentage mark-ups on parts are similarly
priced based on market conditions for different parts. Group 1 Automotive
believes that variable rate pricing helps the Founding Groups to achieve overall
gross margins in parts and service superior to those of certain competitors who
rely on fixed labor rates and percentage markups.
 
     The Founding Groups seek to retain each purchaser of a vehicle as a
customer of the Founding Groups' service and parts departments. The Founding
Groups' dealerships have systems in place that track their customers'
maintenance records and notify owners of vehicles purchased at the dealerships
when their vehicles are due for periodic services. The Founding Groups regard
service and repair activities as an integral part of their overall approach to
customer service, providing an opportunity to foster ongoing relationships with
the Founding Groups' customers and deepen customer loyalty.
 
     The dealerships' parts departments support their respective sales and
service divisions. Each of the Founding Groups' dealerships sells
factory-approved parts for vehicle makes and models sold by that dealership.
These parts are either used in repairs made by the dealership or sold at retail
to its customers or at wholesale to independent repair shops. Currently, each of
the Founding Groups' dealerships employs its own parts manager and independently
controls its parts inventory and sales. Dealerships that sell the same new
vehicle makes have access to each other's computerized inventories and
frequently obtain unstocked parts from other dealerships.
 
  OTHER DEALERSHIP OPERATIONS
 
     Other dealership revenues consist primarily of finance and insurance
income. The Founding Groups arrange financing for their customers' vehicle
purchases, sell vehicle service contracts and arrange selected types of credit
insurance in connection with the financing of vehicle sales. The Founding Groups
place heavy emphasis on finance and insurance ("F&I") and offer advanced F&I
training to their finance and insurance managers. Typically, the Founding
Groups' dealerships forward proposed financing contracts to Manufacturers'
captive finance companies, selected commercial banks or other financing parties.
The Founding Groups receive a finance fee from the lender for arranging the
financing and is typically assessed a charge-back against a portion of the
finance fee if the contract is terminated prior to its scheduled maturity for
any reason, such as early repayment or default. As a result, companies must
 
                                       62
<PAGE>   63
 
arrange financing for a customer that is competitive (i.e., the customer is more
likely to accept the financing terms and the loan is less likely to be
refinanced) and affordable (i.e., the loan is more likely to be repaid).
 
     At the time of a new vehicle sale, the Founding Groups offer extended
service contracts to supplement the Manufacturer warranty. Additionally, the
Founding Groups sell primary service contracts for used vehicles. Currently, the
Founding Groups primarily sell service contracts of third party vendors, for
which they recognize a commission upon the sale of the contract. The Combined
Company also sells its own service contracts at one location and recognizes the
associated revenue over the life of the contract.
 
     The Founding Groups also offer certain types of credit insurance to
customers who finance their vehicle purchases through the Founding Groups. The
Founding Groups sell credit life insurance policies to these customers, which
policies provide for repayment of the vehicle loan if the obligor dies while the
loan is outstanding. The Founding Groups also sell accident and health insurance
policies, which provide payment of the monthly loan obligations during a period
in which the obligor is disabled.
 
FRANCHISE AGREEMENTS
 
     Each of the Founding Groups' dealerships operates pursuant to a franchise
agreement between the applicable Manufacturer and the dealership. The typical
automotive franchise agreement specifies the locations at which the dealer has
the right and the obligation to sell motor vehicles and related parts and
products and to perform certain approved services in order to serve a specified
market area. The designation of such areas and the allocation of new vehicles
among dealerships are subject to the discretion of the Manufacturer, which
generally does not guarantee exclusivity within a specified territory. A
franchise agreement may impose requirements on the dealer concerning such
matters as the showrooms, the facilities and equipment for servicing vehicles,
the maintenance of inventories of vehicles and parts, the maintenance of minimum
net working capital and the training of personnel. Compliance with these
requirements is closely monitored by the Manufacturer. In addition,
Manufacturers require each dealership to submit a financial statement of
operations on a monthly and annual basis. The franchise agreement also grants
the dealer the non-exclusive right to use and display the Manufacturer's
trademarks, service marks and designs in the form and manner approved by the
Manufacturer.
 
     Each franchise agreement sets forth the name of the person approved by the
Manufacturer to exercise full managerial authority over the dealership's
operations and the names and ownership percentages of the approved owners of the
dealership and contains provisions requiring the Manufacturer's prior approval
of changes in management or transfers of ownership of the dealership. Each of
the Founding Groups' dealerships will be owned, directly or indirectly, by Group
1 Automotive, upon consummation of the Acquisitions, at the subsidiary level. A
number of Manufacturers prohibit the acquisition of a substantial ownership
interest in Group 1 Automotive or transactions that may affect management
control of Group 1 Automotive, in each case without the approval of the
Manufacturer. For a description of these and other restrictions and other
material terms imposed by the Manufacturers in the franchise agreements, see
"Risk Factors -- Manufacturers' Control Over Dealerships", "Risk Factors --
Restrictions Imposed by Agreement with American Honda Motor Co., Inc." and "Risk
Factors -- Dependence on Acquisitions for Growth; Manufacturers' Restrictions on
Acquisitions".
 
     Most franchise agreements expire after a specified period of time, ranging
from one to five years, and Group 1 Automotive expects to renew any expiring
agreements in the ordinary course of business. The typical franchise agreement
provides for early termination or non-renewal by the Manufacturer under certain
circumstances such as change of management or ownership without Manufacturer
approval, insolvency or bankruptcy of the dealership, death or incapacity of the
dealer manager, conviction of a dealer manager or owner of certain crimes,
misrepresentation of certain information by the dealership or dealer manager or
owner to the Manufacturer, failure to adequately operate the dealership, failure
to maintain any license, permit or authorization required for the conduct of
business, or material breach of
 
                                       63
<PAGE>   64
 
other provisions of the franchise agreement. The dealership is typically
entitled to terminate the franchise agreement at any time without cause.
 
     The automobile franchise relationship is also governed by various federal
and state laws established to protect dealerships from the general unequal
bargaining power between the parties. The following discussion of state court
and administrative holdings and various state laws is based on management's
beliefs and may not be an accurate description of the state court and
administrative holdings and various state laws. The state statutes generally
provide that it is a violation for a manufacturer to terminate or fail to renew
a franchise without good cause. These statutes also provide that the
manufacturer is prohibited from unreasonably withholding approval for a proposed
change in ownership of the dealership. Acceptable grounds for disapproval
include material reasons relating to the character, financial ability or
business experience of the proposed transferee. Accordingly, certain provisions
of the franchise agreements, particularly as they relate to a manufacturer's
rights to terminate or fail to renew the franchise, have repeatedly been held
invalid by state courts and administrative agencies.
 
     Under Texas law, despite the terms of contracts between manufacturers and
dealers, manufacturers may not unreasonably withhold approval of a transfer of a
dealership. It is unreasonable under Texas law for a manufacturer to reject a
prospective transferee of a dealership who is of good moral character and who
otherwise meets the manufacturer's written, reasonable and uniformly applied
standards or qualifications relating to the prospective transferee's business
experience and financial qualifications. In addition, under Texas and Oklahoma
law and the laws of other states, franchised dealerships may challenge
manufacturers' attempts to establish new franchises in the franchised dealers'
markets, and state regulators may deny applications to establish new dealerships
for a number of reasons, including a determination that the manufacturer is
adequately represented in the region. Texas and Oklahoma law limit the ability
of manufacturers to terminate or fail to renew franchises. In addition, other
laws in Texas and elsewhere limit the ability of manufacturers to withhold their
approval for the relocation of a franchise or require that disputes be
arbitrated. In addition, a manufacturer's license to distribute vehicles in
Texas and Oklahoma may be revoked if, among other things, the manufacturer has
forced or attempted to force an automobile dealer to accept delivery of motor
vehicles not ordered by that dealer. In Oklahoma, a manufacturer's license to
operate in the state may be revoked or suspended upon a finding that a
manufacturer has coerced or intimidated a dealer or acted dishonestly or failed
to act in accordance with reasonable standards of fair dealing.
 
COMPETITION
 
     The automotive retailing industry is extremely competitive. In large
metropolitan areas, consumers have a number of choices in deciding where to
purchase a new or used vehicle and where to have such a vehicle serviced.
 
     In the new vehicle area, the Founding Groups compete with other franchised
dealers in each of its marketing areas. The Founding Groups do not have any cost
advantage in purchasing new vehicles from the Manufacturers, and typically
relies on advertising and merchandising, sales expertise, service reputation and
location of its dealerships to sell new vehicles. In recent years, automobile
dealers have also faced increased competition in the sale or lease of new
vehicles from independent leasing companies, on-line purchasing services and
warehouse clubs. In addition, Ford Motor has announced that it is exploring the
possibility of going into business with some of its dealers to create automotive
superstores in selected markets.
 
     In used vehicles, the Founding Groups compete with other franchised
dealers, independent used car dealers, automobile rental agencies, private
parties and used car "superstores" for supply and resale of used vehicles. Used
car "superstores" have recently opened in certain markets in which the Founding
Groups compete, including Houston, Texas. In addition, the Founding Groups
expect that additional used car "superstores" will open in other markets in
which the Founding Groups compete. See "-- Used Vehicle Sales".
 
                                       64
<PAGE>   65
 
     Group 1 Automotive believes that the principal competitive factors in
vehicle sales are the marketing campaigns conducted by Manufacturers, the
ability of dealerships to offer a wide selection of the most popular vehicles,
the location of dealerships and the quality of customer service. Other
competitive factors include customer preference for particular brands of
automobiles, pricing (including Manufacturer rebates and other special offers)
and warranties. Group 1 Automotive believes that the Founding Groups'
dealerships are competitive in all of these areas.
 
     The Founding Groups compete against franchised dealers to perform warranty
repairs and against other automobile dealers, franchised and independent service
center chains and independent garages for non-warranty repair and routine
maintenance business. The Founding Groups compete with other automobile dealers,
service stores and auto parts retailers in its parts operations. Group 1
Automotive believes that the principal competitive factors in parts and service
sales are price, the use of factory-approved replacement parts, the familiarity
with a Manufacturer's brands and models and the quality of customer service. A
number of regional or national chains offer selected parts and services at
prices that may be lower than the Founding Groups' prices.

GOVERNMENTAL REGULATIONS
 
     A number of regulations affect the Founding Groups' business of marketing,
selling, financing and servicing automobiles. The Founding Groups also are
subject to laws and regulations relating to business corporations generally.
 
     Under Texas and Oklahoma law, the Founding Groups must obtain a license in
order to establish, operate or relocate a dealership or provide certain
automotive repair services. These laws also regulate the Founding Groups'
conduct of business, including its advertising and sales practices. Other states
may have similar requirements.
 
     The Founding Groups' financing activities with its customers are subject to
federal truth in lending, consumer leasing and equal credit opportunity
regulations as well as state and local motor vehicle finance laws, installment
finance laws, insurance laws, usury laws and other installment sales laws. Some
states regulate finance fees that may be paid as a result of vehicle sales.
Penalties for violation of any of these laws or regulations may include
revocation of certain licenses, assessment of criminal and civil fines and
penalties, and in certain instances, create a private cause of action for
individuals. Group 1 Automotive believes that the Founding Groups comply
substantially with all laws and regulations affecting their business and do not
have any material liabilities under such laws and regulations and that
compliance with all such laws and regulations will not, individually or in the
aggregate, have a material adverse effect on the Founding Groups' capital
expenditures, earnings, or competitive position, and Group 1 Automotive does not
anticipate that such compliance will have a material effect on the Combined
Company in the future.
 
ENVIRONMENTAL MATTERS
 
     The Founding Groups are subject to a wide range of federal, state, and
local environmental laws and regulations, including those governing discharges
to the air and water, the storage of petroleum substances and chemicals, the
handling and disposal of wastes, and the remediation of contamination arising
from spills and releases. As with automobile dealerships generally, and service
and parts and collision repair center operations in particular, the Founding
Groups' business involves the generation, use, handling and disposal of
hazardous or toxic substances or wastes. Operations involving the management of
hazardous and nonhazardous wastes are subject to requirements of the federal
Resource Conservation and Recovery Act and comparable state statutes. Pursuant
to these laws, federal and state environmental agencies have established
approved methods for storage, treatment, and disposal of regulated wastes with
which the Founding Groups must comply.
 
     The Founding Groups' business also involves the use of aboveground and
underground storage tanks. Under applicable laws and regulations, the Founding
Groups are responsible for the proper use, maintenance and abandonment of
regulated storage tanks owned or operated by it, and for remediation of
subsurface soils and groundwater impacted by releases from such existing or
abandoned aboveground or underground storage tanks. In addition to these
regulated tanks, the Founding Groups own, operate, or have otherwise abandoned
other underground and aboveground devices or containers (e.g., automotive lifts
and service pits) that may not be classified as regulated tanks, but which are
capable of releasing stored materials into the environment, thereby potentially
obligating the Founding Groups to remediate any soils or groundwater resulting
from such releases.
 
                                       67
<PAGE>   68
 
     The Founding Groups are also subject to laws and regulations governing
remediation of contamination at facilities it operates or to which it sends
hazardous or toxic substances or wastes for treatment, recycling or disposal.
The Comprehensive Environmental Response, Compensation and Liability Act
("CERCLA"), also known as the "Superfund" law, imposes liability, without regard
to fault or the legality of the original conduct, on certain classes of persons
that are considered to have contributed to the release of a "hazardous
substance" into the environment. These persons include the owner or operator of
the disposal site or sites where the release occurred and companies that
disposed or arranged for the disposal of the hazardous substances released at
such sites. Under CERCLA, these "responsible parties" may be subject to joint
and several liability for the costs of cleaning up the hazardous substances that
have been released into the environment, for damages to natural resources and
for the costs of certain health studies, and it is not uncommon for neighboring
landowners and other third parties to file claims for personal injury and
property damage allegedly caused by the release of hazardous substances.
 
     Further, the Federal Water Pollution Control Act, also known as the Clean
Water Act, and comparable state statutes prohibit discharges of pollutants into
regulated waters without authorized National Pollution Discharge Elimination
System (NPDES) and similar state permits, require containment of potential
discharges of oil or hazardous substances, and require preparation of spill
contingency plans. The Combined Company expects to implement programs that
address wastewater discharge requirements as well as containment of potential
discharges and spill contingency planning.
 
     Environmental laws and regulations have become very complex and it has
become very difficult for businesses that routinely handle hazardous and
non-hazardous wastes to achieve and maintain full compliance with all applicable
environmental laws. Like virtually any network of automobile dealerships and
vehicle service facilities, from time to time the Founding Groups can be
expected to experience incidents and encounter conditions that will not be in
compliance with environmental laws and regulations. However, none of the
Founding Groups have been subject to any material environmental liabilities in
the past and Group 1 Automotive does not anticipate that any material
environmental liabilities will be incurred in the future. Furthermore, Group 1
Automotive is in the process of establishing an environmental management program
that is intended to reduce the risk of noncompliance with environmental laws and
regulations. Nevertheless, environmental laws and regulations and their
interpretation and enforcement are changed frequently and Group 1 Automotive
believes that the trend of more expansive and more strict environmental
legislation and regulations is likely to continue. Hence, there can be no
assurance that compliance with environmental laws or regulations or the future
discovery of unknown environmental conditions will not require additional
expenditures by the Combined Company, or that such expenditures would not be
material. See "Risk Factors -- Governmental Regulations and Environmental
Matters".
 
EMPLOYEES
 
     As of June 30, 1997, Group 1 Automotive and the Founding Groups, taken as a
whole, employed 1,503 people, of whom approximately 196 were employed in
managerial positions, 533 were employed in non-managerial sales positions, 551
were employed in non-managerial parts and service positions and 223 were
employed in administrative support positions. Group 1 Automotive intends, upon
completion of the Offering, to provide certain executive officers and managers
with options to purchase Common Stock and believes this equity incentive will be
attractive to existing and prospective employees of the Combined Company. See
"Management -- 1996 Stock Incentive Plan" and "1998 Employee Stock Purchase
Plan".
 
     Group 1 Automotive and the Founding Groups believe that their relationships
with their employees are favorable. None of the such employees is represented by
a labor union. Because of its dependence on the Manufacturers, however, the
Combined Company may be affected by labor strikes, work slowdowns and walkouts
at the Manufacturers' manufacturing facilities.
 
                                       68
<PAGE>   69
 
LEGAL PROCEEDINGS AND INSURANCE
 
     From time to time, the Founding Groups are named in claims involving the
manufacture of automobiles, contractual disputes and other matters arising in
the ordinary course of the Founding Groups' business. Currently, no legal
proceedings are pending against or involve the Founding Groups or Group 1
Automotive that, in the opinion of management, could be expected to have a
material adverse effect on the business, financial condition or results of
operations of the Combined Company.
 
     Because of their vehicle inventory and nature of business, automobile
retail dealerships generally require significant levels of insurance covering a
broad variety of risks. The Combined Company's insurance will include an
umbrella policy with a $50 million per occurrence limit upon consummation of the
Offering as well as insurance on its real property, comprehensive coverage for
its vehicle inventory, general liability insurance, employee dishonesty coverage
and errors and omissions insurance in connection with its vehicle sales and
financing activities.

    Acquisitions and the Offering.
 
     Group 1 Automotive anticipates that during 1997, its most highly
compensated executive officers will be Messrs. Hollingsworth, Howard, McCall,
Smith, Turner and Thompson. Each of these executive officers will enter into an
employment agreement with the Combined Company, which will be effective upon
consummation of the Acquisitions and the Offering. The employment agreements
will provide for the following base salaries for 1997: B.B. Hollingsworth,
Jr. -- $360,000; Robert E. Howard, II -- $300,000; Sterling B. McCall,
Jr. -- $300,000; Charles M. Smith -- $300,000; John T. Turner -- $250,000; and
Scott L. Thompson -- $180,000. The employment agreements will also provide that
such officers' participation in bonus plans will be governed by the bonus and
incentive plans adopted by the Board of Directors in which the officer is a
participant. Currently, the Board of Directors has not adopted any bonus or
incentive plans.
 
     Each employment agreement is for a term of five years, and unless
terminated or not renewed by the Combined Company or the employee, the term will
continue thereafter on a month-to-month basis terminable at any time by either
the Combined Company or the employee, with or without cause, upon thirty days
notice. In the event of a termination of employment by the Combined Company
without cause or by the employee due to an uncorrected material breach of the
employment agreement by the Combined Company, the employee is entitled to
receive his or her base salary paid bi-weekly until the end of his contract
term. In the event of an involuntary termination of employment following a
merger, consolidation or dissolution of the Combined Company or a sale of all
its assets, the employee is entitled to a lump sum payment equal to the amount
of base pay he is entitled to under the remainder of his contract. The Combined
Company is not obligated to pay any amounts to the employee other than his pro
rata base salary through the date of his or her termination upon (i) voluntary
termination of employment by the employee; (ii) termination of employment by the
Combined Company for cause (as defined); (iii) death of the employee; or (iv)
long-term disability of the employee. During the period of employment and for a
period of three years after termination of employment, the employees are
generally prohibited from competing or assisting others to compete with the
Combined Company. Mr. Howard, however, will be permitted to own and operate the
Chevrolet dealership in Tulsa, Oklahoma, together with other related franchises,
if the Combined Company's agreement to acquire the Tulsa Chevrolet dealership is
terminated. See "The Acquisitions". In addition, during the period of employment
and for a period of five years after termination of employment, the employees
are generally prohibited from inducing any other employee to terminate
employment with the Combined Company.

1996 STOCK INCENTIVE PLAN
 
     In November 1996, the Board of Directors and the stockholders of Group 1
Automotive adopted the Combined Company's 1996 Stock Incentive Plan (the
"Plan"). The purpose of the Plan is to provide directors, employees (key
operating managers at the dealerships) and consultants of Group 1 Automotive and
its subsidiaries additional incentive and reward opportunities designed to
enhance the profitable growth of the Combined Company. The Plan provides for the
granting of incentive stock options intended to qualify under Section 422 of the
Code, options that do not constitute incentive stock options and restricted
stock awards. The Plan is administered by the Compensation Committee of the
Board of Directors. In general, the Compensation Committee is authorized to
select the recipients of awards and the terms and conditions of those awards.
 
     The number of shares of Common Stock that may be issued under the Plan may
not exceed 2,000,000 shares (subject to adjustment to reflect stock dividends,
stock splits, recapitalizations and similar changes in the Combined Company's
capital structure). Shares of Common Stock which are attributable to awards
which have expired, terminated or been canceled or forfeited are available for
issuance or use in connection with future awards. The maximum number of shares
of Common Stock that may be subject to awards granted under the Plan to any one
individual during any calendar year may not exceed 500,000 (subject to
adjustment to reflect stock dividends, stock splits, recapitalizations and
similar changes in the Combined Company's capital structure).
 
     The price at which a share of Common Stock may be purchased upon exercise
of an option granted under the Plan will be determined by the Compensation
Committee but (i) in the case of an incentive stock option, such purchase price
will not be less than the fair market value of a share of Common Stock on the
date such option is granted, and (ii) in the case of an option that does not
constitute an incentive stock option, such purchase price will not be less than
80% of the fair market value of a share of Common Stock on the date such option
is granted. Shares of Common Stock that are the subject of a restricted stock
award under the Plan will be subject to restrictions on disposition by the
holder of such award and an obligation of such holder to forfeit and surrender
the shares to the under certain circumstances (the "Forfeiture Restrictions").
The Forfeiture Restrictions will be determined by the Compensation Committee in
its sole discretion, and the Compensation Committee may provide that the
Forfeiture Restrictions will lapse upon (a) the attainment of one or more
performance targets established by the Compensation Committee, (b) the award
holder's continued employment with the Combined Company or continued service as
a consultant or director for a specified period of time, (c) the occurrence of
any event or the satisfaction of any other condition specified by the
Compensation Committee in its sole discretion or (d) a combination of any of the
foregoing.
 
     No awards under the Plan may be granted after ten years from the date the
Plan was adopted by the Board of Directors. The Plan will remain in effect until
all awards granted under the Plan have been satisfied or expired. The Board of
Directors in its discretion may terminate the Plan at any time with respect to
any shares of Common Stock for which awards have not been granted. The Plan may
be amended, other than to increase the maximum aggregate number of shares that
may be issued under the Plan or to change the class of individuals eligible to
receive awards under the Plan, by the Board of Directors without the consent of
the stockholders of the Combined Company. No change in any award previously
granted under the Plan may be made which would impair the rights of the holder
of such award without the approval of the holder.
 
     In December 1996, Group 1 Automotive issued options to purchase 205,000
shares of Common Stock at $2.90 per share as follows: 125,000 shares to John T.
Turner and 80,000 shares to Scott L. Thompson. Each of these options will vest
16.7% per year after the issuance of the options. In March 1997, Group 1
Automotive issued options to purchase an additional 360,000 shares of Common
Stock at $2.90 per share to certain employees of the Combined Company, including
the following executive officers: B.B. Hollingsworth, Jr. -- 100,000 shares,
John T. Turner -- 80,000 shares and Scott L. Thompson -- 80,000 shares. In
addition, upon consummation of the Acquisitions and the Offering, the Combined
Company will issue options to purchase 661,700 shares of Common Stock at the
initial public

offering price to certain employees and directors of the Combined Company,
including the following executive officers: Mr. Hollingsworth -- 100,000, Mr.
Turner -- 125,000 and Mr. Thompson -- 80,000.

1998 EMPLOYEE STOCK PURCHASE PLAN
 
     In September 1997, the Board of Directors and the stockholders of Group 1
Automotive adopted Group 1 Automotive's 1998 Employee Stock Purchase Plan (the
"Purchase Plan"). The Purchase Plan authorizes the issuance of up to 200,000
shares of Common Stock (subject to adjustment in the event of stock dividends,
stock splits and certain other events) and provides that no options may be
granted under the Purchase Plan after June 30, 2007. The Purchase Plan is
available to all employees of the Combined Company and its participating
subsidiaries who are employed as of January 1, 1998 or the first day of each
successive April, July, October and January thereafter (a "Date of Grant").
However, an employee may not be granted an option under the Purchase Plan if
after the granting of the option such employee would be deemed to own 5% or more
of the combined voting power or value of all classes of stock of the Combined
Company. A committee appointed by the Board of Directors (the "Committee") is
charged with the general administration of the Purchase Plan and has the
authority to designate any present or future subsidiary of the Combined Company
as a participating subsidiary.
 
     For each three-month period beginning on a Date of Grant (an "Option
Period") during the term of the Purchase Plan, unless the Committee determines
otherwise, each eligible employee may authorize payroll deductions to be made
during the Option Period, which amounts are used at the end of the Option Period
to acquire shares of Common Stock at 85% of the fair market value of the Common
Stock on the first or the last day of the Option Period, whichever is lower.
Employees have discretion to determine the amount of their payroll deduction
under the Purchase Plan, subject to the limit that not more than 10% of
compensation may be deducted in any Option Period and other limitations set
forth in Section 423 of the Code. No employee may purchase Common Stock under
the Purchase Plan valued at more than $25,000 for each calendar year in
accordance with the provisions of the Code. An employee may withdraw from the
Purchase Plan, in whole but not in part, at any time prior to the last day of an
Option Period, by delivering a withdrawal notice to the Combined Company. In the
event an employee withdraws, the Combined Company will refund the entire amount
of the payroll deductions during the Option Period, without interest.

                              CERTAIN TRANSACTIONS
 
     In connection with the formation of Group 1 Automotive in December 1995,
Group 1 Automotive issued 1,000 shares of Common Stock for $500 to Smith & Liu
Management Company, a Texas general partnership which has provided management
services to the Smith Group dealerships prior to consummation of the
Acquisitions ("Smith & Liu"). Mr. Smith is a partner of Smith & Liu and a
director of Group 1 Automotive. In July 1996, Group 1 Automotive acquired 1,000
shares of Common Stock from Smith & Liu for aggregate consideration of $500 and
issued 500 shares to Mr. Hollingsworth for an aggregate consideration of $5,000.
Subsequently, Group 1 Automotive split its outstanding common stock on a
900-for-one basis accomplished as a stock dividend. For a description of the
Acquisitions, see "The Acquisitions".
 
     In order to finance the expenses of Group 1 Automotive prior to the
Acquisitions and the Offering, Smith & Liu, the Howard Group, the McCall Group,
the Smith Group and the Kingwood Group made loans to Group 1 Automotive, as of
October 29, 1997, of $87,960, $353,626, $592,231, $504,399 and $144,170,
respectively. These advances all have maturities of less than one year and bear
interest at a rate of 7% per annum. As of October 29, 1997, interest accrued on
loans from Smith & Liu, the Howard Group, the McCall Group, the Smith Group and
the Kingwood Group equaled $5,941, $7,928, $20,759, $14,701 and $4,759,
respectively.
 
     Certain officers, directors and stockholders, or their affiliates, of Group
1 Automotive have engaged in transactions with the Founding Companies prior to
consummation of the Acquisitions. Except for the transactions described below,
none of these transactions will continue after consummation of the Acquisitions.
For a discussion of these transactions for the three years ended December 31,
1996 and for the six months ended June 30, 1997, see the Notes to the Combined
Financial Statements of each of the Founding Groups.
 
LEASES
 
     Certain of the properties leased by the Founding Companies are owned by
officers, directors or holders of 5% or more of the Common Stock of the Combined
Company or their affiliates. As part of the Acquisitions, the Founding Companies
have agreed to replace each of the existing leases with officers, directors or
5% stockholders (the "Related Party Leases") with a standard lease agreement for
each property. However, one Related Party Lease, covering the real estate and
facilities of the Howard collision repair center, will remain in place between
Bob Howard Honda/Acura, as lessee, and North Broadway Real Estate, an Oklahoma
limited liability company owned 50% by Robert E. Howard II and 50% by an
unrelated third party. This lease provides for a five-year term ending July 1,
1999 and a monthly rental rate of $9,000, and requires Bob Howard Honda/Acura to
pay all applicable property taxes, maintain adequate insurance and repair or
replace the leased building if necessary.
 
     The term of each lease that is to be replaced is for 30 years and is
cancelable at the Combined Company's option ten years from execution of the
lease and at the end of each subsequent five year period. Additionally, the
Combined Company has a right of first refusal to acquire the property. The lease
requires the Combined Company to be responsible for taxes, insurance and, in
certain circumstances, maintenance. Each of the Related Party Leases and the
rents payable thereunder are described below. Under each of the Related Party
Leases, the rent is subject to increases every five years based on increases in
the Consumer Price Index. Group 1 Automotive believes that the terms of the
Related Party Leases, taken as a whole, will be no less favorable to the
Combined Company than could be obtained from unaffiliated parties.
 
     Sterling McCall Toyota leases property owned by SMC Investment, Inc. ("SMC
Investment") and used by Sterling McCall Toyota as a repair center. Mr. McCall
and his affiliates own all of the stock of SMC Investment. The lease provides
for a monthly rental of $7,000 per month. The property and fixtures subject to
this lease secure indebtedness of SMC Investment. The amount of such
indebtedness outstanding as of June 30, 1997 was approximately $0.7 million.

which Mr. McCall is a partner and that is used by SMC Luxury Cars as an

of Mr. McCall. The amount of such indebtedness outstanding as of June 30, 1997
was approximately $3.4 million.
 
     Sterling McCall Lexus leases property that is owned by Mr. McCall and that
is used by Sterling McCall Lexus as a repair center. The lease provides for a
monthly rental of $6,500. The property subject to this lease secures
indebtedness of Mr. McCall. The amount of such indebtedness outstanding as of
June 30, 1997 was approximately $0.4 million.
 
     Mike Smith Autoplaza leases property owned by a general partnership, of
which the children of Charles M. Smith are partners. The property is used by
Mike Smith Autoplaza as an automobile dealership. The leases provide for monthly
rental payments of $46,500. The property and fixtures subject to this lease
secure indebtedness of an affiliate of Mr. Smith. The amount of such
indebtedness outstanding as of June 30, 1997 was approximately $2.2 million.
 
     Round Rock Nissan leases property owned by SKLR Round Rock, L.L.C., a Texas
limited liability corporation in which Charles M. Smith, has an ownership
interest. The property is used by Round Rock Nissan as an automobile dealership.
The lease provides for current monthly rental payments of $32,000. The property
and fixtures subject to this lease secure indebtedness of an affiliate of Mr.
Smith. The amount of such indebtedness outstanding as of June 30, 1997 was
approximately $2.4 million.
 
     Bob Howard Automall leases two properties owned by Mr. Howard and used by
Bob Howard Automall as automobile dealerships. These leases relating to these
properties provide for aggregate monthly rentals of $85,862. The property and
fixtures subject to this lease secure indebtedness of Mr. Howard. The amount of
such indebtedness outstanding as of June 30, 1997 was approximately $3.6
million.
 
     Bob Howard Chevrolet leases property owned by Mr. Howard and used by Bob
Howard Chevrolet as an automobile dealership. The lease relating to this
property provides for a monthly rental of $48,500. The property and fixtures
subject to this lease secure indebtedness of Mr. Howard. The amount of such
indebtedness outstanding as of June 30, 1997 was approximately $3.3 million.
 
     Bob Howard Honda/Acura leases property owned by North Broadway Real Estate,
L.L.C., an Oklahoma limited liability company in which Mr. Howard owns a 50%
interest. This property is used as a collision repair center, and the lease
relating to this property provides for a monthly rental of $9,000.
 
     Bob Howard Toyota leases property owned by Mr. Howard and used by Bob
Howard Toyota as an automobile dealership. The lease relating to this property
provides for a monthly rental of $33,500. The property and fixtures subject to
this lease secure indebtedness of Mr. Howard. The amount of such indebtedness
outstanding as of June 30, 1997 was $0.9 million.
 
     Certain of the property and the fixtures leased to the Founding Companies
serve as collateral for various indebtedness of the principals of the Founding
Companies and certain affiliates of such principals, as described above. Each of
such principals have agreed to take all action necessary to secure an agreement
from each of the lenders that, upon a default of any of such principals, such
lenders
 
                                       77
<PAGE>   78
 
will honor the lease and will not disturb the Combined Company's right to
possession of the applicable property under the lease. Such principals of the
Founding Companies have also agreed to grant an option to purchase the
applicable leased premises at a price equal to the outstanding indebtedness that
is secured by the property if the principals of the Founding Companies have not
obtained such an agreement from the lenders within 90 days after consummation of
the Acquisitions.
 
LOANS
 
     Certain of the Founding Groups have incurred indebtedness which has been
personally guaranteed by their stockholders or by entities controlled by their
stockholders. Group 1 Automotive intends to repay, refinance or otherwise take
steps to remove these personal guarantees. It is the intention of management
that as soon as practicable after the Acquisitions and the Offering, the debt of
the Combined Company will cease to be personally guaranteed by any of its
officers, directors or stockholders.
 
     The following table sets forth, as of June 30, 1997, the indebtedness of
the Founding Groups which is guaranteed by stockholders of the Founding Groups:

</TABLE>
 
     Certain principals of the Founding Groups, and certain affiliates of such
principals, have incurred indebtedness which is guaranteed by certain of the
Founding Companies. With the exception of the Round Rock Nissan guarantee
described below, all applicable lenders have agreed to release the Founding
Companies from their guarantees of indebtedness of the principals and their
affiliates. These releases will be effective upon the consummation of the
Offering. Following is a list of indebtedness of principals and their affiliates
which will cease to be guaranteed by the Founding Companies upon consummation of
the Offering: Mr. Howard, approximately $7.8 million, Mr. McCall and affiliates,
approximately $8.0 million; and Mr. Smith and affiliates, approximately $2.2
million.
 
     Upon consummation of the Offering, Round Rock Nissan will continue to be a
guarantor of indebtedness incurred by SKLR Round Rock, L.C., a limited liability
company in which Charles M. Smith owns a 22% interest. No other entity
comprising the Combined Company will be liable under Round Rock Nissan's
guarantee. At June 30, 1997, the outstanding principal amount of this
indebtedness was approximately $2.4 million. However, if Round Rock Nissan's
guarantee of this indebtedness is not removed within 90 days after consummation
of the Acquisitions, the Combined Company will have an option to acquire the
land and fixtures securing such indebtedness (which is the property on which
Round Rock Nissan is located) at a price equal to such indebtedness. Group 1
Automotive currently intends to acquire such land and fixtures if the guarantee
is not released. In connection with a proposed
 
                                       78
<PAGE>   79
 
refinancing of SKLR Round Rock, L.C.'s debt on such land and fixtures, a local
real estate appraisal firm provided Group 1 Automotive with a verbal estimate of
value of $2.6 million, which exceeds SKLR Round Rock L.C.'s outstanding loan
balance on such property by approximately $200,000. Since Group 1 Automotive
believes that the fair market value of the property is greater than the
outstanding indebtedness guaranteed by Round Rock Nissan, Group 1 Automotive
expects that the Combined Company would record negative goodwill in connection
with the acquisition.
 
     Upon consummation of the acquisition of Bob Howard East by the Combined
Company (through Bob Howard Automall), the Combined Company will assume a loan
made by Mr. Howard to Bob Howard East. The amount outstanding under this loan is
approximately $2.5 million, and bears interest at the prime rate plus 100 basis
points. If such acquisition is not consummated, this loan will not be assumed by
the Combined Company. See "The Acquisitions".
 
OTHER
 
     Sterling McCall Toyota and Sterling McCall Lexus have entered into an
agreement with Dealer Solutions, L.L.C. ("DSL") pursuant to which DSL is to
provide management information systems software and related services to the
dealerships. Pursuant to the agreement, the dealerships will pay a monthly
maintenance fee of approximately $2,500 until the earlier of the time the
dealerships' existing contract for such services with a different vendor
terminates or March 1999, at which time the monthly maintenance fee will
increase to approximately $12,500 per month for the remainder of the five year
term of the agreement. After an initial five-year term, this agreement is
subject to successive automatic one-year extensions with the same terms and fees
unless terminated by either party with thirty days notice. In addition, upon
installation of the software system at Sterling McCall Lexus, an installation
fee of $20,000 will be paid to DSL. No installation fee has been paid by
Sterling McCall Toyota. Mr. McCall, his affiliates and family members own
approximately 18% of DSL and Kevin H. Whalen (who will beneficially own more
than 5% of the outstanding shares of Common Stock after the Acquisitions and the
Offering) owns approximately 11% of DSL. Group 1 Automotive is currently only
committed to implement this system in Sterling McCall Toyota and Sterling McCall
Lexus. Group 1 Automotive does not currently have any formal plans to implement
this system in its other dealerships. Group 1 Automotive believes that the
Combined Company will acquire these systems from DSL on terms, taken as a whole,
that are no less favorable than those that could be obtained from non-affiliated
third parties.

                          DESCRIPTION OF CAPITAL STOCK
 
     The Combined Company's authorized capital stock consists of 50,000,000
shares of Common Stock and 1,000,000 shares of Preferred Stock, par value $.01
per share ("Preferred Stock"). After giving effect to the Acquisitions, but
prior to consummation of the Offering, the Combined Company will have
outstanding 9,524,914 shares of Common Stock and no shares of Preferred Stock.
Upon completion of the Offering, the Combined Company will have outstanding
13,953,050 shares of Common Stock (14,673,050 shares if the Underwriters'
over-allotment option is exercised in full) and no shares of Preferred Stock.
 
COMMON STOCK
 
     Subject to any special voting rights of any series of Preferred Stock that
may be issued in the future, the holders of the Common Stock are entitled to one
vote for each share held on all matters voted upon by stockholders, including
the election of directors. Holders of Common Stock are not entitled to cumulate
their votes in elections of directors.
 
     Subject to the rights of any then outstanding shares of Preferred Stock,
the holders of the Common Stock are entitled to such dividends as may be
declared in the discretion of the Board of Directors out of funds legally
available therefor. Holders of Common Stock are entitled to share ratably in the
net assets of Group 1 Automotive upon liquidation after payment or provision for
all liabilities and any preferential liquidation rights of any Preferred Stock
then outstanding. The holders of Common Stock have no preemptive rights to
purchase shares of stock of Group 1 Automotive. Shares of Common Stock are not
subject to any redemption provisions and are not convertible into any other
securities of Group 1 Automotive. All outstanding shares of Common Stock are,
and the shares of Common Stock to be issued pursuant to the Offering will be
upon payment therefor, fully paid and non-assessable.
 
PREFERRED STOCK
 
     Preferred Stock may be issued from time to time by the Board of Directors
in one or more series. Subject to the provisions of Group 1 Automotive's Charter
and limitations prescribed by law, the Board of Directors is expressly
authorized to adopt resolutions to issue the shares, to fix the number of shares
and to change the number of shares constituting any series and to provide for or
change the voting powers, designations, preferences and relative participating,
optional or other special rights, qualifications, limitations or restrictions
thereof, including dividend rights (including whether dividends are cumulative),
dividend rates, terms of redemption (including sinking fund provisions),
redemption prices, conversion rights and liquidation preferences of the shares
constituting any series of the Preferred Stock, in each case without any further
action or vote by the stockholders. One of the effects of undesignated Preferred
Stock may be to enable the Board of Directors to render more difficult or to
discourage an attempt to obtain control of Group 1 Automotive by means of a
tender offer, proxy contest, merger or otherwise, and thereby to protect the
continuity of Group 1 Automotive's management. The issuance of shares of the
Preferred Stock pursuant to the Board of Directors' authority described above
may adversely affect the rights of the holders of Common Stock. For example,
Preferred Stock issued by Group 1 Automotive may rank prior to the Common Stock
as to dividend rights, liquidation preference or both, may have full or limited
voting rights and may be convertible into shares of Common Stock. Accordingly,
the issuance of shares of Preferred Stock may discourage bids for the Common
Stock or may otherwise adversely affect the market price of the Common Stock.
 
CERTAIN ANTI-TAKEOVER AND OTHER PROVISIONS OF THE CHARTER AND BYLAWS
 
     In addition to Group 1 Automotive's Board of Directors to issue Preferred
Stock, the Charter and the Bylaws of Group 1 Automotive contain certain
provisions that could have an anti-takeover effect.
 
                                       81
<PAGE>   82
 
  CLASSIFIED BOARD OF DIRECTORS AND LIMITATIONS ON REMOVAL OF DIRECTORS
 
     Group 1 Automotive's Board of Directors is divided into three classes. The
directors of each class are elected for three-year terms, with the terms of the
three classes staggered so that directors from a single class are elected at
each annual meeting of stockholders. Stockholders may remove a director only for
cause upon the vote of holders of at least 80% of the voting power of the
outstanding shares of Common Stock. In general, the Board of Directors, not the
stockholders, has the right to appoint persons to fill vacancies on the Board of
Directors.
 
  NO WRITTEN CONSENT OF STOCKHOLDERS
 
     The Charter provides that any action required or permitted to be taken by
the stockholders of the must be taken at a duly called annual or special meeting
of stockholders. In addition, special meetings of the stockholders may be called
only by the Board of Directors.
 
  BUSINESS COMBINATIONS UNDER DELAWARE LAW
 
     Group 1 Automotive is a Delaware corporation and is subject to Section 203
of the Delaware General Corporation Law. In general, Section 203 prevents an
"interested stockholder" (defined generally as a person owning 15% or more of
Group 1 Automotive's outstanding voting stock) from engaging in a "business
combination" (as defined in Section 203) with Group 1 Automotive for three years
following the date that person becomes an interested stockholder unless (a)
before that person became an interested stockholder, Group 1 Automotive's Board
of Directors approved the transaction in which the interested stockholder became
an interested stockholder or approved the business combination; (b) upon
completion of the transaction that resulted in the interested stockholder
becoming an interested stockholder, the interested stockholder owns at least 85%
of the voting stock outstanding at the time the transaction commenced (excluding
stock held by directors who are also officers of Group 1 Automotive and by
employee stock plans that do not provide employees with the right to determine
confidentially whether shares held subject to the plan will be tendered in a
tender or exchange offer); or (c) following the transaction in which that person
became an interested stockholder, the business combination is approved by the
Combined Company's Board of Directors and authorized at a meeting of
stockholders by the affirmative vote of the holders of at least two-thirds of
the outstanding voting stock not owned by the interested stockholder. Under
Section 203, these restrictions also do not apply to certain business
combinations proposed by an interested stockholder following the announcement or
notification of one of certain extraordinary transactions involving Group 1
Automotive and a person who was not an interested stockholder during the
previous three years or who became an interested stockholder with the approval
of a majority of Group 1 Automotive's directors, if that extraordinary
transaction is approved or not opposed by a majority of the directors who were
directors before any person became an interested stockholder in the previous
three years or who were recommended for election or elected to succeed such
directors by a majority of such directors then in office.
 
STOCKHOLDER RIGHTS PLAN
 
     Immediately prior to completion of the Offering, Group 1 Automotive's
Rights Plan (the "Rights Plan") will take effect. Under the Rights Plan, each
Right entitles the registered holder under the circumstances described below to
purchase from Group 1 Automotive one one-thousandth of a share of Junior
Participating Preferred Stock, $.01 par value per share (the "Preferred
Shares"), of Group 1 Automotive at a price of $65 per one one-thousandth of a
Preferred Share (the "Purchase Price"), subject to adjustment. The description
and terms of the Rights will be set forth in a Rights Agreement (the "Rights
Agreement") to be entered into by Group 1 Automotive and ChaseMellon
Shareholders Services, L.L.C., as Rights Agent (the "Rights Agent") prior to
consummation of the Offering and this description of the Rights is qualified in
its entirety by reference to the Rights Agreement.
 
     Until the Distribution Date (as defined below), the Rights will attach to
all Common Stock certificates representing outstanding shares and no separate
Right Certificate will be distributed.
 
                                       82
<PAGE>   83
 
Accordingly, a right will be issued for each share of Common Stock issued in the
Offering. The Rights will separate from the Common Stock and a Distribution Date
will occur upon the earlier of (i) 10 business days following a public
announcement that a person or group of affiliated or associated persons other
than certain grandfathered stockholders (an "Acquiring Person") has acquired
beneficial ownership of 20% or more of the outstanding Voting Shares (as defined
in the Rights Agreement) of Group 1 Automotive, or (ii) 10 business days
following the commencement or announcement of an intention to commence a tender
offer or exchange offer the consummation of which would result in the beneficial
ownership by a person or group of 20% or more of such outstanding Voting Shares.
 
     Until the Distribution Date (or earlier redemption or expiration of the
Rights) the Rights will be evidenced by the certificates representing such
Common Stock. As soon as practicable following the Distribution Date, separate
certificates evidencing the Rights (the "Right Certificates") will be mailed to
holders of record of the Common Stock as of the close of business on the
Distribution Date and such separate Right Certificates alone will thereafter
evidence the Rights.
 
     The Rights are not exercisable until the Distribution Date. The Rights will
expire on the tenth anniversary date of the closing of the Offering (the "Final
Expiration Date"), unless the Final Expiration Date is extended or the Rights
are earlier redeemed or exchange by Group 1 Automotive as described below.
 
     If a person or group were to acquire 20% or more of the Voting Shares of
Group 1 Automotive, each Right then outstanding (other than Rights beneficially
owned by the Acquiring Person which would become null and void) would become a
right to buy that number of shares of Common Stock (or under certain
circumstances, the equivalent number of one one-thousandths of a Preferred
Share) that at the time of such acquisition would have a market value of two
times the Purchase Price of the Right.
 
     If Group 1 Automotive were acquired in a merger or other business
combination transaction or assets constituting more than 50% of its consolidated
assets or producing more than 50% of its earning power or cash flow were sold,
proper provision will be made so that each holder of a Right will thereafter
have the right to receive, upon the exercise thereof at the then current
Purchase Price of the Right, that number of shares of common stock of the
acquiring company which at the time of such transaction would have a market
value of two times the Purchase Price of the Right.
 
     The dividend and liquidation rights, and the non-redemption feature, of the
Preferred Shares are designed so that the value of one one-thousandth of a
Preferred Share purchasable upon exercise of each Right will approximate the
value of one share of Common Stock. The Preferred Shares issuable upon exercise
of the Rights will be non-redeemable and rank junior to all other series of
Group 1 Automotive's preferred stock. Each whole Preferred Share will be
entitled to receive a quarterly preferential dividend in an amount per share
equal to the greater of (i) $1.00 in cash, or (ii) in the aggregate, 1,000 times
the dividend declared on the Common Stock. In the event of liquidation, the
holders of Preferred Shares will be entitled to receive a preferential
liquidation payment equal to the greater of (i) $1,000 per share, or (ii) in the
aggregate, 1,000 times the payment made on the shares of Common Stock. In the
event of any merger, consolidation or other transaction in which the shares of
Common Stock are exchanged for or changed into other stock or securities, cash
or other property, each whole Preferred Share will be entitled to receive 1,000
times the amount received per share of Common Stock. Each whole Preferred Share
shall be entitled to 1,000 votes on all matters submitted to a vote of the
stockholders of Group 1 Automotive, and Preferred Shares shall generally vote
together as one class with the Common Stock and any other capital stock on all
matters submitted to a vote of stockholders of Group 1 Automotive.
 
     The offer and sale of the Preferred Shares issuable upon exercise of the
Rights will be registered with the Commission and such registration will not be
effective until the Rights become exercisable.
 
     The number of one one-thousandths of a Preferred Share or other securities
or property issuable upon exercise of the Rights, and the Purchase Price
payable, are subject to customary adjustments from time to time to prevent
dilution.
 
                                       83
<PAGE>   84
 
     The number of outstanding Rights and the number of one one-thousandths of a
Preferred Share issuable upon exercise of each Right are also subject to
adjustment in the event of a stock split of the Common Stock or a stock dividend
on the Common Stock payable in Common Stock or a subdivision, consolidation or
combination of the Common Stock occurring, in any such case, prior to the
Distribution Date.
 
     At any time after the acquisition by a person or group of affiliated or
associated persons of beneficial ownership of 20% or more of the outstanding
Voting Shares of Group 1 Automotive and before the acquisition by a person or
group of 50% or more of the outstanding Voting Shares of Group 1 Automotive, the
Board of Directors may, at its option, issue Common Stock in mandatory
redemption of, and in exchange for, all or part of the then outstanding and
exercisable Rights (other than Rights owned by such person or group which would
become null and void) at an exchange ratio of one share of Common Stock (or one
one-thousandth of a Preferred Share) for each two shares of Common Stock for
which each Right is then exercisable, subject to adjustment.
 
     At any time prior to the first public announcement that a person or group
has become the beneficial owner of 20% or more of the outstanding Voting Shares,
the Board of Directors of Group 1 Automotive may redeem all but not less than
all the then outstanding Rights at a price of $0.01 per Right (the "Redemption
Price"). The redemption of the Rights may be made effective at such time, on
such basis and with such conditions as the Board of Directors in its sole
discretion may establish. Immediately upon the action of the Board of Directors
ordering redemption of the Rights, the right to exercise the Rights will
terminate and the only right of the holders of Rights will be to receive the
Redemption Price.
 
     Until a Right is exercised, the holder thereof, as such, will have no
rights as a stockholder of Group 1 Automotive, including, without limitation,
the right to vote or to receive dividends.
 
     The terms of the Rights may be amended by the Board of Directors of Group 1
Automotive without the consent of the holders of the Rights, including an
amendment to extend the Final Expiration Date, and, provided a Distribution Date
has not occurred, to extend the period during which the Rights may be redeemed,
except that after the first public announcement that a person or group has
become the beneficial owner of 20% or more of the outstanding Voting Shares, no
such amendment may materially and adversely affect the interests of the holders
of the Rights.
 
     The Rights have certain anti-takeover effects. The Rights will cause
substantial dilution to a person or group that attempts to acquire Group 1
Automotive on terms not determined by the Board of Directors to be in the best
interests of all stockholders. The Rights will not interfere with a merger or
other business combination approved by the Board of Directors, prior to the time
that a person or group has acquired beneficial ownership of 20% or more of the
Common Stock, since the rights may be redeemed by Group 1 Automotive prior to
that time.
 
LIMITATION OF LIABILITY OF OFFICERS AND DIRECTORS -- INDEMNIFICATION
 
     Delaware law authorizes corporations to limit or eliminate the personal
liability of officers and directors to corporations and their stockholders for
monetary damages for breach of officers' and directors' fiduciary duty of care.
The duty of care requires that, when acting on behalf of the corporation,
officers and directors must exercise an informed business judgment based on all
material information reasonably available to them. Absent the limitations
authorized by Delaware law, officers and directors are accountable to
corporations and their stockholders for monetary damages for conduct
constituting gross negligence in the exercise of their duty of care. Delaware
law enables corporations to limit available relief to equitable remedies such as
injunction or rescission. The Charter limits the liability of officers and
directors of Group 1 Automotive to Group 1 Automotive or its stockholders to the
fullest extent permitted by Delaware law. Specifically, officers and directors
of Group 1 Automotive will not be personally liable for monetary damages for
breach of an officer's or director's fiduciary duty in such capacity, except for
liability (i) for any breach of the officer's or director's duty of loyalty to
Group 1 Automotive or its stockholders, (ii) for acts or omissions not in good
faith or which involve intentional misconduct or a knowing violation of law,
(iii) for unlawful payments of dividends or unlawful stock repurchases or
 
                                       84
<PAGE>   85
 
redemptions as provided in Section 174 of the Delaware General Corporation Law,
or (iv) for any transaction from which the officer and director derived an
improper personal benefit.
 
     The inclusion of this provision in the Charter may have the effect of
reducing the likelihood of derivative litigation against officers and directors,
and may discourage or deter stockholders or management from bringing a lawsuit
against officers and directors for breach of their duty of care, even though
such an action, if successful, might otherwise have benefitted Group 1
Automotive and its stockholders. Both Group 1 Automotive's Charter and Bylaws
provide indemnification to Group 1 Automotive's officers and directors and
certain other persons with respect to certain matters to the maximum extent
allowed by Delaware law as it exists now or may hereafter be amended. These
provisions do not alter the liability of officers and directors under federal
securities laws and do not affect the right to sue (nor to recover monetary
damages) under federal securities laws for violations thereof.
 
TRANSFER AGENT AND REGISTRAR
 
     The transfer agent and registrar of the Common Stock, as well as the rights
agent under the Rights Plan is ChaseMellon Shareholder Services, L.L.C.
 
                        SHARES ELIGIBLE FOR FUTURE SALE
 
     Upon consummation of the Acquisitions and completion of the Offering,
assuming no exercise of the Underwriters' over-allotment option, the Combined
Company will have 13,953,050 shares of Common Stock outstanding (14,673,050
shares if the Underwriters' over-allotment option is exercised in full). Of
these outstanding shares of Common Stock, the 4,800,000 shares sold in the
Offering (5,520,000 shares if the Underwriters' over-allotment option is
exercised in full) will be freely tradeable without restriction unless acquired
by affiliates of the Combined Company. None of the remaining 9,153,050
outstanding shares of Common Stock have been registered under the Securities
Act, which means that they may be resold publicly only upon registration under
the Securities Act or in compliance with an exemption from the registration
requirements of the Securities Act, including the exemption provided by Rule 144
thereunder.
 
     In general, under Rule 144 as currently in effect, if one year has elapsed
since the later of the date of the acquisition of restricted shares of Common
Stock from either Group 1 Automotive or any affiliate of Group 1 Automotive, the
acquiror or subsequent holder thereof may sell, within any three month period
commencing 90 days after the date of this Prospectus, a number of shares that
does not exceed the greater of 1% of the then outstanding shares of the Common
Stock (139,530 shares upon completion of the Offering), or the average weekly
trading volume of the Common Stock on the New York Stock Exchange during the
four calendar weeks preceding the date on which notice of the proposed sale is
sent to the Commission. Sales under Rule 144 are also subject to certain manner
of sale provisions, notice requirements and the availability of current public
information about the Combined Company. If two years have elapsed since the
later of the date of the acquisition of restricted shares of Common Stock from
Group 1 Automotive or any affiliate of Group 1 Automotive, a person who is not
deemed to have been an affiliate of Group 1 Automotive at any time for 90 days
preceding a sale would be entitled to sell such shares under Rule 144 without
regard to the volume limitations, manner of sale provisions or notice
requirements.
 
     Pursuant to the Stock Purchase Agreements entered into in connection with
the Acquisitions, each of the stockholders of the Founding Companies, other than
the Selling Stockholder to the extent of the shares to be sold by him in the
Offering, has agreed with Group 1 Automotive not to sell the shares of Common
Stock that they receive in the Acquisitions for a period of two years after the
date of consummation of the Acquisitions. Pursuant to the Honda Agreement, each
of such stockholders has also agreed not to sell, transfer or otherwise dispose
of such shares of Common Stock, or the voting rights associated therewith,
without the prior written consent of American Honda. In addition, pursuant to an
Underwriting Agreement between Group 1 Automotive, the Selling Stockholder and
the Underwriters, Group 1 Automotive and its officers, directors and
stockholders who beneficially own 9,153,050 shares of
 
                                       85
<PAGE>   86
 
Common Stock in the aggregate have agreed not to sell or otherwise dispose of
any shares of Common Stock and certain other securities of the Combined Company
for a period of 180 days after the date of this Prospectus without the prior
written consent of the representatives. See "Underwriting".
 
     Prior to the Offering, there has been no public market for the Common
Stock. No prediction can be made regarding the effect, if any, that public sales
of shares of Common Stock or the availability of shares for sale will have on
the market price of the Common Stock after the Offering. Sales of substantial
amounts of the Common Stock in the public market following the Offering, or the
perception that such sales may occur, could adversely affect the market price of
the Common Stock and could impair the ability of the Combined Company to raise
capital through sales of its equity securities.

</TABLE>
 
     Under the terms and conditions of the Underwriting Agreement, the
Underwriters are committed to take and pay for all of the shares offered hereby,
if any are taken.
 
     The Underwriters propose to offer the shares of Common Stock in part
directly to the public at the initial public offering price set forth on the
cover page of this Prospectus, and in part to certain securities dealers at such
price less a concession of $0.45 per share. The Underwriters may allow, and such
dealers may reallow, a concession not in excess of $0.10 per share to certain
brokers and dealers. After the shares of Common Stock are released for sale to
the public, the offering price and other selling terms may from time to time be
varied by the representatives.
 
     Group 1 Automotive has granted the Underwriters an option exercisable for
30 days after the date of this Prospectus to purchase up to an aggregate of
720,000 additional shares of Common Stock to cover over-allotments, if any. If
the Underwriters exercise their over-allotment option, the Underwriters have
severally agreed, subject to certain conditions, to purchase approximately the
same percentage thereof that the number of shares to be purchased by each of
them, as shown in the foregoing table, bears to the 4,800,000 shares of Common
Stock offered.
 
     Group 1 Automotive, its officers and directors and the stockholders of
Group 1 Automotive, including the Selling Stockholder, have agreed that, during
the period beginning from the date of this Prospectus and continuing to and
including the date 180 days after the date of this Prospectus, they will not
offer, sell, contract to sell or otherwise dispose of any shares of Common
Stock, any securities of the Combined Company which are substantially similar to
the shares of Common Stock or which are convertible or exchangeable for
securities which are substantially similar to the shares of Common Stock (other
than (i) pursuant to employee stock option plans existing, or on the conversion
or exchange of convertible or exchangeable securities outstanding, on the date
of this Prospectus or (ii) in connection with and as consideration for
acquisitions of automobile dealerships; provided that the proposed transferee
agrees in writing for the benefit of the Underwriters to be bound by the
foregoing provisions) without the prior
 
                                       87
<PAGE>   88
 
written consent of the representatives, except for the shares of Common Stock
offered in connection with the Offering.
 
     The representatives of the Underwriters have informed Group 1 Automotive
that they do not expect sales to accounts over which the Underwriters exercise
discretionary authority to exceed five percent of the total number of shares of
Common Stock offered by them.
 
     Prior to this Offering, there has been no public market for the shares. The
initial public offering price was negotiated among Group 1 Automotive, the
Selling Stockholder and the representatives. Among the factors considered in
determining the initial public offering price of the Common Stock, in addition
to prevailing market conditions, were the Founding Groups' historical
performance, estimates of the business potential and earnings prospects of the
Combined Company, an assessment of the Combined Company's management and the
consideration of the above factors in relation to market valuation of companies
in related businesses.
 
     The Common Stock has been approved for listing, subject to notice of
issuance, on the New York Stock Exchange under the symbol "GPI". In order to
meet one of the requirement for listing the Common Stock on the New York Stock
Exchange, the Underwriters have undertaken to sell lots of 100 or more shares to
a minimum of 2,000 beneficial holders.
 
     In connection with the Offering, the Underwriters may purchase and sell
Common Stock in the open market. These transactions may include overallotment
and stabilizing transactions and purchases to cover syndicate short positions
created in connection with the Offering. Stabilizing transactions consist of
certain bids or purchases for the purpose of preventing or retarding a decline
in the market price of the Common Stock; and syndicate short positions involve
the sale by the Underwriters of a greater number of shares of Common Stock than
they are required to purchase from Group 1 Automotive in the Offering. The
Underwriters may also impose a penalty bid, whereby selling concessions allowed
to syndicate members or other broker-dealers in respect of the Common Stock sold
in the Offering for their account may be reclaimed by the syndicate if such
Common Stock is repurchased by the syndicate in stabilizing or covering
transactions. These activities may stabilize, maintain or otherwise affect the
market price of the Common Stock which may be higher than the price that might
otherwise prevail in the open market. These transactions may be effected on the
New York Stock Exchange, in the over-the-counter market or otherwise, and these
activities, if commenced, may be discontinued at any time.
 
     Group 1 Automotive and the Selling Stockholder have agreed to indemnify the
several Underwriters against certain liabilities, including liabilities under
the Securities Act of 1933.
 
                            VALIDITY OF COMMON STOCK
 
     The validity of the shares of Common Stock offered hereby is being passed
upon for Group 1 Automotive and the Selling Stockholder by Vinson & Elkins
L.L.P., Houston, Texas, and for the Underwriters by Sullivan & Cromwell, New
York, New York. John S. Watson, the Secretary of the Combined Company, is a
partner of Vinson & Elkins L.L.P.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To Group 1 Automotive, Inc.,
 
     We have examined the pro forma adjustments reflecting the transactions
described in Note 2 and the application of those adjustments to the historical
amounts in the accompanying pro forma combined statement of operations of Group
1 Automotive, Inc. for the year ended December 31, 1996. The historical combined
statement of operations was derived from the historical financial statements of
Group 1 Automotive, Inc., Howard Group, McCall Group and Smith Group, which were
audited by us, appearing elsewhere herein, and Kingwood Group, which was audited
by us and not separately presented herein. Such pro forma adjustments are based
upon management's assumptions described in Notes 3, 4 and 5. Our examination was
made in accordance with standards established by the American Institute of
Certified Public Accountants and, accordingly, included such procedures as we
considered necessary in the circumstances.
 
     In addition, we have reviewed the related pro forma adjustments reflecting
the transactions described in Note 2 and the application of those adjustments to
the historical amounts in the accompanying pro forma combined balance sheet of
Group 1 Automotive, Inc. as of June 30, 1997, and the pro forma combined
statement of operations for the six months then ended. These historical combined
financial statements were derived from the historical unaudited financial
statements of Group 1 Automotive, Inc., Howard Group, McCall Group, and Smith
Group which were reviewed by us, appearing elsewhere herein, and Kingwood Group,
which was reviewed by us, and not appearing elsewhere herein. Such pro forma
adjustments are based on management's assumptions as described in Notes 3, 4 and
5. Our review was conducted in accordance with standards established by the
American Institute of Certified Public Accountants.
 
     The objective of this pro forma financial information is to show what the
significant effects on the historical information might have been had the
transaction occurred at an earlier date. However, the pro forma combined
financial statements are not necessarily indicative of the results of operations
or related effects on financial position that would have been attained had the
above-mentioned transaction actually occurred earlier.
 
     In our opinion, management's assumptions provide a reasonable basis for
presenting the significant effects directly attributable to the above-mentioned
transaction described in Note 2, the related pro forma adjustments give
appropriate effect to those assumptions, and the pro forma column reflects the
proper application of those adjustments to the historical financial statement
amounts in the pro forma combined statement of operations for the year ended
December 31, 1996.
 
     A review is substantially less in scope than an examination, the objective
of which is the expression of an opinion on management's assumptions, the pro
forma adjustments and the application of those adjustments to historical
financial information. Accordingly, we do not express such an opinion on the pro
forma adjustments or the application of such adjustments to the pro forma
combined balance sheet as of June 30, 1997, and the pro forma combined statement
of operations for the six months then ended. Based on our review, however,
nothing came to our attention that caused us to believe that management's
assumptions do not provide a reasonable basis for presenting the significant
effects directly attributable to the above mentioned transaction described in
Note 2, that the related pro forma adjustments do not give appropriate effect to
those assumptions, or that the pro forma and as adjusted columns do not reflect
the proper application of those adjustments to the historical financial
statement amounts in the pro forma combined balance sheet as of June 30, 1997,
and the pro forma combined statement of operations for the six months then
ended.

                NOTES TO PRO FORMA COMBINED FINANCIAL STATEMENTS
 
1. GROUP 1 AUTOMOTIVE, INC.
 
     Group 1 Automotive, Inc. has conducted no operations to date and will
acquire the Founding Groups immediately prior to the closing of the Offering.
 
2. BASIS OF PRESENTATION
 
     The pro forma combined financial statements give effect to the acquisitions
by Group 1 Automotive, Inc. (Group 1), of substantially all of the net assets of
(a) Howard Group (Howard), (b) McCall Group (McCall), (c) Smith Group (Smith)
and (d) Kingwood Group (Kingwood), (together, the Founding Groups) and the
initial public offering of 4,428,136 shares of the common stock of Group 1.
Group 1 and the Founding Groups are hereinafter referred to as the Company.
These acquisitions (the Acquisitions) will occur immediately prior to the
closing of Group 1's public offering (the Offering) and will be accounted for
using the purchase method of accounting. Howard, one of the Founding Groups, has
been identified as the acquiror for financial statement presentation purposes in
accordance with SAB No. 97 as it will hold the single largest voting interest
subsequent to the Acquisitions. The pro forma combined financial statements also
give effect to the issuance of Common Stock, which will be issued by Group 1 to
the sellers of the Founding Groups immediately prior to the Offering. These
statements are based on the historical financial statements of the Founding
Groups included elsewhere in this Prospectus (except Kingwood, which has been
excluded as it is not a significant subsidiary under SAB No. 80) and the
estimates and assumptions set forth below.
 
     The pro forma combined balance sheet gives effect to these transactions
(the Acquisitions and the Offering) as if they had occurred on June 30, 1997.
The pro forma combined statements of operations for the year ended December 31,
1996 and the six months ended June 30, 1997 give effect to these transactions as
if they had occurred at the beginning of the periods (January 1, 1996 and
January 1, 1997, respectively).
 
     Included in the pro forma combined balance sheet and statement of
operations are amounts related to Honda and Acura dealerships (See "Risk
Factors -- Restrictions Imposed by Agreement with American Honda Motor Co.,
Inc."). These dealerships represent, as of June 30, 1997, current assets of
approximately $19.4 million, total assets of approximately $20.9 million,
current liabilities of approximately $17.9 million and total liabilities of
approximately $18.3 million. Additionally, these dealerships contributed
revenues of approximately $63.0 million and $123.3 million and income before
income taxes of approximately $1.3 million and $3.3 million for the six months
ended June 30, 1997 and the year ended December 31, 1996, respectively.

be paid its common stockholders in shares of Common Stock.

(1) Excludes $2.3 million and $3.1 million in cash consideration to be paid to
    Howard and Kingwood Groups, respectively.
 
(2) Includes 592,303 shares of Common Stock issued to an owner of the Howard
    Group which will be held in escrow and distributed pro rata to the
    stockholders of the Founding Groups if the Combined Company's acquisition of
    the Chevrolet dealership in Tulsa, Oklahoma is not consummated with General
    Motors' approval within two years of the Offering. The pro rata distribution
    will be allocated among the Founding Groups as follows: the McCall Group,
    161,913 shares; the Smith Group, 190,340 shares; the Howard Group, 207,940
    shares; and the Kingwood Group, 32,110 shares.
 
     Since the Howard Group is the accounting acquiror for financial statement
presentation purposes, the pro forma combined financial statements do not give
effect to the value of the 592,303 shares of stock which are held in escrow and
may be issued to a stockholder of the Howard Group upon the Combined Company's
acquisition of the Chevrolet dealership in Tulsa, Oklahoma. However, the shares
held in escrow have been included in determining the weighted average shares
outstanding for the year ended December 31, 1996 and the six months ended June
30, 1997 since those shares will continue to be outstanding even if the Combined
Company is unable to acquire the Chevrolet dealership. In the event that the
acquisition is not completed, the shares which are held in escrow will be
distributed pro rata to the stockholders of the Founding Groups and will be
treated as contingent consideration in accordance with APB 16 "Business
Combinations". Based on the allocation of these shares to the stockholders, the
Company would recognize additional goodwill of approximately $3.0 million in
conjunction with the acquisitions.
 
     The holders of approximately 8,703,050 shares of Common Stock issued in
payment of the Acquisitions have agreed not to offer, sell or otherwise dispose
of any of those shares for a period of two years after the Offering and do not
have registration rights. The fair value of these shares reflects this
restriction. The remaining 371,864 shares of Common Stock issued in payment of
the Acquisitions will be sold by a shareholder at the date of the offering, and
accordingly, the value of those shares has not been adjusted from the Offering
price.
 
     Based upon management's preliminary analysis, it is anticipated that the
historical carrying value of the Founding Groups' assets and liabilities will
approximate fair value. The amount of goodwill subsequent to the Acquisitions is
$31.9 million, with $30.5 million attributable to the acquisitions, and $1.4
million attributable to the existing goodwill of the Howard Group, the
accounting acquiror. The Company will use an estimated life of 40 years for the
amortization of goodwill. Management of Group 1 has not identified any other
material tangible or identifiable intangible assets of the Founding Groups to
which a portion of the purchase price could reasonably be allocated.

To Group 1 Automotive, Inc.:
 
     We have audited the accompanying balance sheets of Group 1 Automotive, Inc.

the year ended December 31, 1996. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing

reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of the Company as of December
31, 1995 and 1996, and the results of its operations and cash flows for the

                         NOTES TO FINANCIAL STATEMENTS
(All discussions and disclosures with a reference date subsequent to May 9, 1997
                                are unaudited.)
1. BUSINESS AND ORGANIZATION:
 
     Group 1 Automotive, Inc. (Group 1 or the Company), was founded on December
21, 1995 to become a leading operator and consolidator in the automotive
retailing industry. Group 1 intends to acquire 30 automobile dealerships and
related businesses which are currently owned by four dealership groups located
in Texas and Oklahoma (the Founding Groups) (the Acquisitions), complete an
initial public offering (the Offering) of its common stock and, subsequent to
the Offering, continue to acquire, through merger or purchase, similar companies
to expand its national and regional operations.
 
     Group 1's primary assets at December 31, 1996 and June 30, 1997 are cash
and deferred offering costs. Group 1 has not conducted any operations, and all
activities to date have related to the Acquisitions. There is no assurance that
the Acquisitions discussed below will be completed and that Group 1 will be able
to generate future operating revenues. Funding for the deferred offering costs
has been provided by the Founding Groups. Group 1 is dependent upon the Offering
to fund the amounts due to the Founding Groups and future operations. In the
event that the Offering is not completed, Group 1 will pursue alternative
sources of funding in order to meet its current obligations.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Major Suppliers and Franchise Agreements
 
     The Founding Groups purchase substantially all of their new vehicles from
various manufacturers at the prevailing prices charged by the manufacturers to
all franchised dealers. Group 1's sales volume subsequent to the Acquisitions
could be adversely impacted by the manufacturers' inability to supply the
dealerships with an adequate supply of popular models or as a result of an
unfavorable allocation of vehicles by the manufacturers.
 
     The dealer franchise agreements contain provisions which may limit changes
in dealership management and ownership, place certain restrictions on the
dealerships (such as minimum net worth requirements) and which also provide for
termination of the franchise agreement by the manufacturers in certain
instances. Subsequent to the Acquisitions, Group 1's ability to acquire
additional franchises from a particular manufacturer may be limited due to
certain restrictions imposed by manufacturers, the Company's ability to enter
into significant acquisitions may be restricted and the acquisition of the
Company's stock by third parties may be limited by the terms of the franchise
agreement. See "Risk Factors -- Manufacturers Control Over Dealerships" and
"Business -- Franchise Agreements" for further discussion.
 
  Property and Equipment
 
     Property and equipment are recorded at cost and depreciated using the
straight-line method over the estimated useful lives of the assets.
 
  Other Assets
 
     The Company has capitalized all costs incurred in connection with the
Offering as a component of other assets in the accompanying financial
statements. Upon completion of the Offering, all such costs will be offset
against additional paid-in capital. Deferred offering costs capitalized in other
assets totaled approximately $767,000 and $2,777,000 as of December 31, 1996 and
June 30, 1997, respectively.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
  Income Taxes
 
     The Company follows the liability method of accounting for income taxes in
accordance with Statement of Financial Accounting Standards (SFAS) No. 109.
Under this method, deferred income taxes are recorded based upon differences
between the financial reporting and tax bases of assets and liabilities and are
measured using the enacted tax rates and laws that will be in effect when the
underlying assets are received or liabilities are settled.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions in determining the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
3. NEW ACCOUNTING PRONOUNCEMENTS
 
     During June 1996 the Financial Accounting Standards Board (FASB) issued
statement of Financial Accounting Standards (SFAS) No. 125 "Accounting for
Transfers and Servicing of Financial Assets and Extinguishment of Liabilities."
During February 1997 the FASB issued SFAS No. 128 and 129 "Earnings per Share"
and "Disclosure of Information about Capital Structure," respectively, and in
June 1997 issued SFAS No. 130 and 131 "Reporting Comprehensive Income" and
"Disclosures about Segments of an Enterprise and Related Information,"
respectively. The major provisions of these statements and their impact on the
Company are discussed below.
 
     SFAS No. 125 established criteria for recognition of a sale in conjunction
with the transfer of financial assets, under which sales may only be recognized
when the transferor has surrendered control of the assets. This statement is not
currently anticipated to have any impact on the Company as the Company does not
currently enter into transactions which fall under the scope of this statement.
 
     SFAS No. 128 requires the presentation of basic earnings per share and
diluted earnings per share in financial statements of public enterprises rather
than primary and fully diluted earnings per share as previously required. Under
the provisions of this statement, basic earnings per share will be computed
based on weighted average shares outstanding and will exclude dilutive
securities such as options, warrants, etc. Diluted earnings per share will be
computed including the impacts of all potentially dilutive securities. The
Company will adopt this statement in December 1997, but does not anticipate that
the statement will have an impact on the Company as the Company does not have a
significant number of potentially dilutive securities outstanding.
 
     SFAS No. 129 will require additional disclosure of information about an
entity's capital structure, including information about dividend and liquidation
preferences, voting rights, contracts to issue additional shares, conversion and
exercise prices, etc. The Company will adopt this statement in December 1997.
 
     SFAS No. 130 requires the presentation of comprehensive income in an
entity's financial statements. Comprehensive income represents all changes in
equity of an entity during the reporting period, including net income and
charges directly to equity which are excluded from net income. This statement is
not anticipated to have any impact on the Company as the Company currently does
not enter into any transactions which result in charges (or credits) directly to
equity (such as additional minimum pension liability changes, currency
translation adjustments, unrealized gains and losses on available for sale
securities, etc.).

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
     SFAS No. 131 will be adopted by the Company during 1998, SFAS No. 131
provides revised disclosure guidelines for segments of an enterprise based on a
management approach to defining operating segments. The Company currently
operates in only one industry segment and analyzes operations on a Company-wide
basis, therefore the statement is not expected to impact the Company.
 
  Interim Financial Information
 
     As is normal and customary, the interim financial statements as of June 30,
1997, and for the six months ended June 30, 1996 and 1997, are unaudited, and
certain information normally included in financial statements prepared in
accordance with generally accepted accounting principles has not been included
herein. In the opinion of management, all adjustments necessary to fairly
present the financial position, results of operations and cash flows with
respect to the interim financial statements, have been properly included. Due to
seasonality and other factors, the results of operations for the interim periods
are not necessarily indicative of the results that will be realized for the
entire fiscal year.
 
  Statements of Cash Flows
 
     For purposes of the statements of cash flows, cash and cash equivalents
include all highly liquid debt instruments purchased with an original maturity
of three months or less.
 
3. CAPITAL STOCK AND STOCK OPTIONS
 
     Group 1 effected a 900-for-one-stock split on December 13, 1996. The effect
of the common stock split has been accounted for as a stock dividend in the
accompanying financial statements. On February 5, 1997 the Board of Directors
increased the authorized number of shares of common stock from 2,000,000 to
50,000,000, and authorized the issuance of up to 1,000,000 shares of preferred
stock.
 
     The Company has approved the 1996 Stock Incentive Plan (the Plan), which
provides for the granting or awarding of stock options, stock appreciation
rights and restricted stock to nonemployee directors, officers and other key
employees (including officers of the Founding Groups) and independent
contractors. The number of shares authorized and reserved for issuance under the
Plan is 2,000,000 shares. In general, the terms of the option awards (including
vesting schedules) will be established by the Compensation Committee of the
Company's Board of Directors. As of December 31, 1996, the Company has granted
options to employees covering an aggregate of 205,000 shares of common stock.
During March 1997, the Company granted additional options to employees to
purchase an aggregate of 360,000 shares of common stock under the Plan. All
outstanding options are exercisable over a period not to exceed 10 years and
vest over a six year period. The exercise price of the options under the Plan is
at least 100 percent of the estimated fair market value of the stock at the time
the option is granted.
 
     In October 1995, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards (SFAS) No. 123, "Accounting for Stock-Based
Compensation," which, if fully adopted, requires the Company to record
stock-based compensation at fair value. The Company has adopted the disclosure
requirements of SFAS No. 123 and has elected to record employee compensation
expense in accordance with Accounting Principles Board (APB) Opinion No. 25.
Accordingly, compensation expense is recorded for stock options based on the
excess of the fair market value of the common stock on the date the options were
granted over the aggregate exercise price of the options. As the exercise price
of options granted under the Plan has been equal to or greater than the market
price of the Company's stock on the date of grant, no compensation expense
related to the Plan has been recorded.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
Had compensation expense for the Plan been determined consistent with SFAS No.
123, the impact on the Company's net loss would have been as follows for the
year ended December 31, 1996:
 
<TABLE>

Net loss as reported........................................  $ 95,008
Pro forma net loss..........................................  $102,640
</TABLE>
 
     At December 31, 1996 and June 30, 1997, no options were exercisable and
1,795,000 and 1,435,000 options, respectively, were available for future grant
under the Plan. The exercise prices of options outstanding under the Plan at
December 31, 1996 and June 30, 1997, were $2.90. The weighted average
contractual life of options outstanding at December 31, 1996 and June 30, 1997,
was 10 years. The weighted average fair value of options granted during the year
ended December 31, 1996 and the six month period ended June 30, 1997, was $2.90.
The fair value of each option grant is estimated on the date of grant using the
minimum value method with the following weighted average assumptions: a weighted
average risk-free interest rate of 5.0 percent; no expected dividend yields; and
expected lives of four years.
 
4. INCOME TAXES
 
     The following tables set forth the components of the Company's deferred tax
assets as of December 31, 1996 along with a reconciliation of income tax for the
year ended December 31, 1996. The Company has recorded a valuation allowance
against its deferred tax assets as in management's opinion it is more likely
than not that such amounts may not be realized in future periods.

(1) Includes 592,303 shares of Common Stock issued to an owner of the Howard
    Group which will be held in escrow and distributed pro rata to the
    stockholders of the Founding Groups if the Combined Company's acquisition of
    the Chevrolet dealership in Tulsa, Oklahoma is not consummated with General
    Motors' approval within two years of the Offering. The pro rata distribution
    will be allocated among the Founding Groups as follows: the McCall Group,
    161,913 shares; the Smith Group, 190,340 shares; the Howard Group, 207,940
    shares; and the Kingwood Group, 32,110 shares. Since the Howard Group is the
    accounting acquiror for financial statement presentation purposes, the pro
    forma combined financial statements do not give effect to the value of the
    592,303 shares of stock which are held in escrow and may be issued to a
    stockholder of the Howard Group upon the Combined Company's acquisition of
    the Chevrolet dealership in Tulsa, Oklahoma. However, the shares held in
    escrow have been included in determining the weighted average shares
    outstanding for the year ended December 31, 1996 and the six months ended
    June 30, 1997 since those shares will continue to be outstanding even if the
    Combined Company is unable to acquire the Chevrolet dealership. In the event
    that the acquisition is not completed, the shares which are held in escrow
    will be distributed pro rata to the stockholders of the Founding Groups and
    will be treated as contingent consideration in accordance with APB 16
    "Business Combinations". Based on the allocation of those shares to the
    stockholders, the Company would recognize additional goodwill of
    approximately $3.0 million in conjunction with the acquisitions.
 
     In conjunction with the Acquisitions and the Offering, the Founding Groups
have advanced funds to the Company for operations and offering costs. As of
December 31, 1996, these advances totaled $150,987 and accrued interest at a
rate of 7% per annum. As of October 14, 1997, these advances totaled $1,682,386.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To Howard Group:
 
     We have audited the accompanying combined balance sheets of the companies
identified in Note 1 (the Companies) as of December 31, 1995 and 1996, and the
related combined statements of operations, stockholders' equity and cash flows
for each of the three years in the period ended December 31, 1996. These
financial statements are the responsibility of the Companies' management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of the Companies as of December
31, 1995 and 1996, and the results of their operations and their cash flows for
each of the three years in the period ended December 31, 1996, in conformity
with generally accepted accounting principles.

(All discussions and disclosures with a reference date subsequent to May 9, 1997
                                are unaudited.)
 
1. BUSINESS AND ORGANIZATION:
 
     Howard Group (the Companies) is primarily engaged in the retail sale of new
and used automobiles and the sale of the related finance, insurance and service
contracts thereon. In addition, the Companies sell automotive parts, provide
vehicle servicing and sell wholesale used vehicles.
 
     The following companies are included within the combined group:
 
          Howard Pontiac -- GMC, Inc. (Automall)
 
         Automall consists of several franchises which conduct business at
         contiguous locations in Oklahoma City, Oklahoma. The franchises
         operated in this location include Pontiac, GMC, Mazda, Isuzu, Jeep,
         Eagle, Chrysler and Plymouth.
 
          Bob Howard Chevrolet, Inc. (BHC)
 
         BHC is a Chevrolet dealership located in Oklahoma City, Oklahoma.
 
          Bob Howard Automotive -- H, Inc. (BHH)
 
         BHH consists of two franchises, Honda and Acura, which conduct business
         at contiguous locations in Oklahoma City, Oklahoma.
 
          Bob Howard Motors, Inc. (BHT)
 
         BHT is a Toyota dealership located in Oklahoma City, Oklahoma.
 
          Bob Howard Dodge, Inc. (BHD)
 
         BHD is a Dodge dealership located in Oklahoma City, Oklahoma.
 
     The Companies and their stockholders intend to enter into a definitive

outstanding shares of the Companies' common stock will be exchanged for cash and
shares of Group 1's common stock concurrent with the consummation of the initial
public offering of the common stock of Group 1.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
  Basis of Presentation
 
     The accompanying combined financial statements include the accounts of the
companies listed above. The Companies have been presented on a combined basis
due to their related operations, common ownership and common management control.
All significant intercompany balances and transactions have been eliminated in
combination.
 
  Major Suppliers and Franchise Agreements
 
     The Companies purchase substantially all of their new vehicles at the
prevailing prices charged by the manufacturers to all franchised dealers. The
Companies' sales volume could be adversely impacted by the manufacturers'
inability to supply the dealership with an adequate supply of popular models or
as a result of an unfavorable allocation of vehicles by the manufacturer.
 
     The dealer franchise agreements contain provisions which may limit changes
in dealership management and ownership, place certain restrictions on the
dealerships (such as minimum working capital requirements), and which also
provide for termination of the franchise agreement by the manufacturers in
certain instances. Under certain state law, these restrictive provisions have
been repeatedly found invalid

both by state courts and administrative agencies. See "Risk
Factors -- Manufacturers' Control Over Dealerships" and "Business -- Franchise
Agreements" for further discussion.
 
  Revenue Recognition
 
     Revenue from vehicle sales, parts sales and vehicle service is recognized
upon delivery to the customer.
 
  Finance, Insurance and Service Contract Income Recognition
 
     The Companies arrange financing for customers through various institutions
and receive financing fees equal to the difference between the loan rates
charged to customers over the predetermined financing rates set by the financing
institution. In addition, the Companies receive commissions from the sale of
credit life and disability insurance and extended service contracts to
customers.
 
     The Companies may be charged back (chargebacks) for unearned financing
fees, insurance or service contract commissions in the event of early
termination of the contracts by customers. The revenues from financing fees and
commissions are recorded at the time of the sale of the vehicles. The reserves
for future chargebacks are based on historical operating results and the
termination provisions of the applicable contracts. Finance, insurance and
service contract income, net of estimated chargebacks, are included in other
dealership revenue in the accompanying combined financial statements.
 
  Cash and Cash Equivalents
 
     Cash and cash equivalents include highly liquid investments that have an
original maturity of three months or less at the date of purchase and contracts
in transit. Contracts in transit represent contracts on vehicles sold, for which
the proceeds are in transit from financing institutions.
 
  Inventories
 
     New, used and demonstrator vehicles are stated at the lower of cost or
market, determined on a specific-unit basis.
 
     Parts and accessories are stated at the lower of cost (determined on a
first-in, first-out basis) or market.
 
  Property and Equipment
 
     Property and equipment are recorded at cost and depreciated using the
straight-line method over the estimated useful lives of the assets. Leasehold
improvements are capitalized and amortized over the lesser of the life of the
lease or the estimated useful life of the asset.
 
     Expenditures for major additions or improvements which extend the useful
lives of assets are capitalized. Minor replacements, maintenance and repairs
which do not improve or extend the life of such assets are charged to operations
as incurred. Disposals are removed at cost less accumulated depreciation, and
any resulting gain or loss is reflected in current operations.
 
  Goodwill
 
     Goodwill represents the excess of the purchase price of dealerships
acquired (BHH, BHD and Automall) over the fair value of assets acquired at the
date of acquisition. Goodwill is being amortized on a straight-line basis over
40 years. Amortization expense charged to operations totaled approximately
$21,000, $27,000 and $36,000 for the years ended December 31, 1994, 1995 and
1996, respectively.

                                  HOWARD GROUP
 
             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
 
Accumulated amortization totaled approximately $93,000 and $129,000 as of
December 31, 1995 and 1996, respectively.
 
  Income Taxes
 
     The Companies follow the liability method of accounting for income taxes in
accordance with Statement of Financial Accounting Standards (SFAS) No. 109.
Under this method, deferred income taxes are recorded based upon differences
between the financial reporting and tax bases of assets and liabilities and are
measured using the enacted tax rates and laws that will be in effect when the
underlying assets are realized or liabilities are settled. A valuation allowance
reduces deferred tax assets when it is more likely than not that some or all of
the deferred tax assets will not be realized.
 
     Certain of the Companies have elected S Corporation status, as defined by
the Internal Revenue Code, whereby the Companies are not subject to taxation for
federal purposes. Under S Corporation status, the stockholders report their
share of these Companies' taxable earnings or losses in their personal tax
returns.
 
  Environmental Liabilities and Expenditures
 
     Accruals for environmental matters, if any, are recorded in operating
expenses when it is probable that a liability has been incurred and the amount
of the liability can be reasonably estimated. Accrued liabilities are exclusive
of claims against third parties and are not discounted.
 
     In general, costs related to environmental remediation are charged to
expense. Environmental costs are capitalized if the costs increase the value of
the property and/or mitigate or prevent contamination from future operations.
 
  Interest Expense
 
     Automobile manufacturers periodically provide floorplan interest
assistance, or subsidies, which reduce the Companies' cost of financing. The
accompanying combined financial statements reflect interest expense net of
floorplan assistance.
 
  Fair Value of Financial Instruments
 
     The Companies' financial instruments consist primarily of floor plan notes
payable and long-term debt. The carrying amount of these financial instruments
approximates fair value due either to length of maturity or existence of
variable interest rates that approximate market rates.
 
  Advertising
 
     The Company expenses production and other costs of advertising as incurred.
Advertising expense for the years ended December 31, 1994, 1995 and 1996 totaled
$3,511,447, $3,422,453 and $3,245,451, respectively.
 
  Concentration of Credit Risk
 
     Financial instruments which potentially subject the Companies to a
concentration of credit risk consist principally of cash, cash equivalents,
contracts in transit and accounts receivable. The Company maintains cash
balances at financial institutions which may at times be in excess of federally
insured levels. The Companies grant credit to local companies in various
businesses. The Companies perform ongoing credit evaluations of their customers
and generally do not require collateral. The Companies maintain an allowance for
doubtful accounts at a level which management believes is sufficient to cover

             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
 
potential credit losses. The Companies have not incurred significant losses
related to these financial instruments to date.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions in determining the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. The significant estimates made by management in the
accompanying financial statements relate to reserves for future chargebacks on
finance, insurance and service contract income. Actual results could differ from
those estimates.
 
  Interim Financial Information
 
     As is normal and customary, the interim financial statements as of June 30,
1997, and for the six months ended June 30, 1996 and 1997, are unaudited, and
certain information normally included in financial statements prepared in
accordance with generally accepted accounting principles has not been included
herein. In the opinion of management, all adjustments necessary to fairly
present the financial position, results of operations and cash flows with
respect to the interim financial statements, have been properly included. Due to
seasonality and other factors, the results of operations for the interim periods
are not necessarily indicative of the results that will be realized for the
entire fiscal year.
 
  Statements of Cash Flows
 
     For purposes of the statements of cash flows, cash and cash equivalents
include contracts in transit which are typically collected within one month.
Additionally, the net change in floor plan financing of inventory, which is a
customary financing technique in the industry, is reflected as an operating
activity in the statements of cash flows.
 
  New Accounting Pronouncement
 
     Effective January 1, 1996, the Companies adopted SFAS No. 121, "Accounting
for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed
Of." SFAS No. 121 requires that long-lived assets be reviewed for impairment
whenever events or changes in circumstances indicate that the carrying amount of
the asset in question may not be recoverable. If an evaluation is required, the
estimated future undiscounted cash flows associated with the asset would be
compared to the asset's carrying amount to determine if a write-down to market
value or discounted cash flow value is necessary. Adoption of this standard did
not have a material effect on the financial position or results of operations of
the Companies.
 
     During June 1996 and June 1997 the Financial Accounting Standards Board
(FASB) issued statement of Financial Accounting Standards (SFAS) No. 125
"Accounting for Transfers and Servicing of Financial Assets and Extinguishment
of Liabilities" and SFAS No. 130 "Reporting Comprehensive Income, respectively."
The major provisions of these statements and their impact on the Company are
discussed below.
 
     SFAS No. 125 established criteria for recognition of a sale in conjunction
with the transfer of financial assets, under which sales may only be recognized
when the transferor has surrendered control of the assets. This statement is not
currently anticipated to have any impact on the Company as the Company does not
currently enter into transactions which fall under the scope of this statement.
 
     SFAS No. 130 requires the presentation of comprehensive income in an
entity's financial statements. Comprehensive income represents all changes in
equity of an entity during the reporting period, including net income and
charges directly to equity which are excluded from net income. This statement is
not

anticipated to have any impact on the Company as the Company currently does not
enter into any transactions which result in charges (or credits) directly to
equity (such as additional minimum pension liability changes, currency
translation adjustments, unrealized gains and losses on available for sale
securities, etc.).

10. COMMITMENTS AND CONTINGENCIES:
 
  Litigation
 
     The Companies are defendants in several lawsuits arising from normal
business activities. Management has reviewed pending litigation with legal
counsel and believes that the ultimate liability, if any, resulting from such
actions will not have a material adverse effect on the Companies' financial
position or results of operations.
 
  Insurance
 
     The Companies carry a standard range of insurance coverage, including
general and business auto liability, commercial property, workers' compensation
and excess liability coverage. The Companies have not incurred significant
claims or losses on any of their insurance policies.
 
  Stockholder Loans Guaranteed by the Companies
 
     The principal stockholder of the Companies has various loans totaling
$8,128,000 and $7,766,120 outstanding with a financial institution as of
December 31, 1996 and June 30, 1997. The loans are guaranteed by Automall, BHC
and BHT and are secured by all of the real estate, buildings and improvements at
the dealerships. The notes mature on various dates through 2004 and bear
interest at prime less .5% (8.25% at December 31, 1996).
 
11. RETIREMENT PLAN:
 
     Effective April 1, 1996, the Companies established a 401(k) salary
deferral/savings plan for the benefit of all employees. Employees electing to
participate in the plan may contribute up to 15% of annual compensation, limited
to the maximum amount that can be deducted for income tax purposes each year.
 
     The Companies, at their discretion, have the option to match each
employee's contribution up to a maximum of 6% of annual compensation each plan
year. The Companies elected to make contributions totaling $178,000 for the year
ended December 31, 1996.
 
12. PROPOSED ACQUISITION BY GROUP 1:
 
     The stockholders of the Companies intend to enter into definitive purchase
agreements with Group 1 providing for the purchase of the Companies by Group 1.
In conjunction with the acquisition of the Companies by Group 1, all existing
operating leases with related parties will be restructured under new lease
agreements and the principal stockholder of the Companies will either obtain
releases for the Companies from the stockholder loan guarantees discussed above
or will obtain alternative financing in order to obtain release from the
stockholder loan guarantees.

     In conjunction with the proposed Acquisition by Group 1, the Howard Group
will make distributions from the S-Corporation accumulated adjustment accounts
to certain shareholders totaling $4,500,000. The pro forma balance sheet as of
June 30, 1997 gives effect to these distributions as of June 30, 1997.
 
14. SUBSEQUENT EVENTS (UNAUDITED)
 
     During 1997, an affiliate of the Howard Group entered into an agreement to
acquire, subject to manufacturer approval, a Chevrolet dealership in Tulsa,
Oklahoma. The Howard Group has not received approval from the manufacturer, and
in June 1997, entered into a management contract with the owner of the Chevrolet
dealership. Group 1 expects to enter into an agreement to acquire the Chevrolet
dealership from the affiliate of the Howard Group for the assumption of the
dealership's liabilities.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
TO MCCALL GROUP:
 
     We have audited the accompanying combined balance sheets of the companies
identified in Note 1 (the Companies) as of December 31, 1995 and 1996, and the
related combined statements of operations, stockholders' deficit and cash flows
for each of the three years in the period ended December 31, 1996. These
financial statements are the responsibility of the Companies' management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

                     NOTES TO COMBINED FINANCIAL STATEMENTS
(All discussions and disclosures with a reference date subsequent to May 9, 1997
                                are unaudited.)
 
1. BUSINESS AND ORGANIZATION:
 
     McCall Group (the Companies) is primarily engaged in the retail sale of new
and used automobiles and the sale of the related finance, insurance and service
contracts thereon. In addition, the Companies sell automotive parts, provide
vehicle servicing and sell wholesale used vehicles.
 
     The following companies are included within the combined group:
 
     Southwest Toyota, Inc. (d.b.a. Sterling McCall Toyota) (SMT) -- SMT is a
Toyota dealership located in Houston, Texas.
 
     SMC Luxury Cars, Inc. (d.b.a. Sterling McCall Lexus) (SML) -- SML is a
Lexus dealership located in Houston, Texas.
 
     The Companies and their stockholders intend to enter into a definitive
agreement with Group 1 Automotive, Inc. (Group 1), pursuant to which all
outstanding shares of the Companies' common stock will be exchanged for cash and
shares of Group 1's common stock concurrent with the consummation of the initial
public offering of the common stock of Group 1.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
  Basis of Presentation
 
     The accompanying combined financial statements include the accounts of SMT
and SML. The Companies have been presented on a combined basis due to their
related operations, common ownership and common management control. All
significant intercompany balances and transactions have been eliminated in
combination. SMC Investments, Inc. (SMC) owns 100% of the issued and outstanding
stock of SML and approximately 51% of the stock of SMT. SMC is a separate
holding company which does not operate in the automobile retailing industry and
has not been included in the accompanying combined financial statements as it
will not be acquired by Group 1.
 
  Major Suppliers and Franchise Agreements
 
     The Companies purchase substantially all of their new vehicles from Toyota
Motor Corp. at the prevailing prices charged by the manufacturers to all
franchised dealers. The Companies' sales volume could be adversely impacted by
the manufacturers' inability to supply the dealership with an adequate supply of
popular models or as a result of an unfavorable allocation of vehicles by the
manufacturer.
 
     The dealer franchise agreements contain provisions which may limit changes
in dealership management and ownership, place certain restrictions on the
dealerships (such as minimum net worth requirements) and which also provide for
termination of the franchise agreement by the manufacturers in certain
instances. Under certain state law, these restrictive provisions have been
repeatedly found invalid both by state courts and administrative agencies. See
"Risk Factors -- Manufacturers' Control Over Dealerships" and
"Business -- Franchise Agreements" for further discussion.
 
  Revenue Recognition
 
     Revenue from vehicle sales, parts sales and vehicle service is recognized
upon delivery to the customer.
 
  Fleet Sales
 
     SMT periodically supplies vehicles to various rental car companies as an
accommodation to the manufacturer and to better utilize dealership capacity.
These transactions generate nominal gross profit,

and in management's opinion, do not represent sales in the normal course of
business. Accordingly, sales of approximately $8.5 million, $7.7 million and
$10.8 million and cost of sales of approximately $8.1 million, $7.5 million and
$10.7 million have been excluded from the accompanying statements of operations
for the years ended December 31, 1994, 1995 and 1996 as management believes
excluding such amounts represents a more appropriate basis of presentation. The
net profit on these wholesale fleet transactions is recorded as other dealership
revenues in the accompanying statements of operations.
 
  Finance, Insurance and Service Contract Income Recognition
 
     The Companies arrange financing for customers through various institutions
and receive financing fees equal to the difference between the loan rates
charged to customers over the predetermined financing rates set by the financing
institution. In addition, the Companies receive commissions from the sale of
credit life and disability insurance and extended service contracts to
customers.
 
     The Companies may be charged back (chargebacks) for unearned financing
fees, insurance or service contract commissions in the event of early
termination of the contracts by customers. The revenues from financing fees and
commissions are recorded at the time of the sale of the vehicles. The reserves
for future chargebacks are based on historical operating results and the
termination provisions of the applicable contracts. Finance, insurance and
service contract income, net of estimated chargebacks, are included in other
dealership revenue in the accompanying combined financial statements.
 
  Cash and Cash Equivalents
 
     Cash and cash equivalents include highly liquid investments that have an
original maturity of three months or less at the date of purchase and contracts
in transit. Contracts in transit represent contracts on vehicles sold, for which
the proceeds are in transit from financing institutions.
 
  Inventories
 
     New and demonstrator vehicles are stated at cost, determined on the
last-in, first-out (LIFO) basis, which is not in excess of market.
 
     Used vehicles are stated at lower of cost or market, determined on a
specific unit basis.
 
     Parts and accessories are stated at the lower of cost (determined on a
first-in, first-out basis) or market.
 
  Property and Equipment
 
     Property and equipment are recorded at cost and depreciated using the
straight-line method over the estimated useful lives of the assets. Leasehold
improvements are capitalized and amortized over the lesser of the life of the
lease or the estimated life of the asset.
 
     Expenditures for major additions or improvements which extend the useful
lives of assets are capitalized. Minor replacements, maintenance and repairs
which do not improve or extend the life of such assets are charged to operations
as incurred. Disposals are removed at cost less accumulated depreciation, and
any resulting gain or loss is reflected in current operations.
 
  Income Taxes
 
     The Companies follow the liability method of accounting for income taxes in
accordance with Statement of Financial Accounting Standards (SFAS) No. 109.
Under this method, deferred income
 
                                      F-42

                                  MCCALL GROUP
 
             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
 
taxes are recorded based upon differences between the financial reporting and
tax bases of assets and liabilities and are measured using the enacted tax rates
and laws that will be in effect when the underlying assets are realized or
liabilities are settled. SML is a member of a consolidated group for tax
reporting purposes. In accordance with SFAS No. 109, SML reports current and
deferred tax expense using the separate return method, resulting in tax expense
being recorded as if SML filed a separate company return for tax purposes. Under
this method, SML does not recognize benefits for net operating losses (NOL's) as
such amounts will not be refunded to SML by the consolidated group. These NOL
carryforwards are offset against the provision for taxes in subsequent
profitable years and treated as dividends to the parent when benefited. SMT is a
separate tax paying entity and is not a member of a consolidated group.
 
  Environmental Liabilities and Expenditures
 
     Accruals for environmental matters, if any, are recorded as operating
expenses when it is probable that a liability has been incurred and the amount
of the liability can be reasonably estimated. Accrued liabilities are exclusive
of claims against third parties and are not discounted.
 
     In general, costs related to environmental remediation are charged to
expense. Environmental costs are capitalized if the costs increase the value of
the property and/or mitigate or prevent contamination from future operations.
 
  Interest Expense
 
     Automobile manufacturers periodically provide floorplan interest
assistance, or subsidies, which reduce the Companies' cost of financing. The
accompanying financial statements reflect interest expense net of floor plan
assistance.
 
  Fair Value of Financial Instruments
 
     The Companies' financial instruments consist primarily of floor plan notes
payable, notes receivable and long-term debt. The carrying amount of these
financial instruments approximates fair value due either to length of maturity
or existence of variable interest rates that approximate market rates.
 
  Advertising
 
     The Company expenses production and other costs of advertising as incurred.
Advertising expense for the years ended December 31, 1994, 1995 and 1996 totaled
$1,961,488, $2,800,699 and $4,034,050, respectively.
 
  Concentration of Credit Risk
 
     Financial instruments which potentially subject the Companies to a
concentration of credit risk consist principally of cash, cash equivalents,
contracts in transit and accounts receivable. The Company maintains cash
balances at financial institutions which may at times be in excess of federally
insured levels. The Companies grant credit to local companies in various
businesses. The Companies perform ongoing credit evaluations of their customers
and generally do not require collateral. The Companies maintain an allowance for
doubtful accounts at a level which management believes is sufficient to cover
potential credit losses. The Companies have not incurred significant losses
related to these financial instruments to date.

             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions in determining the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. The significant estimates made by management in the
accompanying financial statements relate to reserves for future chargebacks on
finance, insurance and service contract income and reserves for retail loan loss
guarantees (Notes 2 and 11, respectively). Actual results could differ from
those estimates.
 
  Interim Financial Information
 
     As is normal and customary, the interim financial statements as of June 30,
1997, and for the six months ended June 30, 1996 and 1997, are unaudited, and
certain information normally included in financial statements prepared in
accordance with generally accepted accounting principles has not been included
herein. In the opinion of management, all adjustments necessary to fairly
present the financial position, results of operations and cash flows with
respect to the interim financial statements, have been properly included. Due to
seasonality and other factors, the results of operations for the interim periods
are not necessarily indicative of the results that will be realized for the
entire fiscal year.
 
  Statements of Cash Flows
 
     For purposes of the statements of cash flows, cash and cash equivalents
include contracts in transit which are typically collected within one month or
less. Additionally, the net change in floor plan financing of inventory, which
is a customary financing technique in the industry, is reflected as an operating
activity in the statements of cash flows.
 
  New Accounting Pronouncement
 
     Effective January 1, 1996, the Companies adopted SFAS No. 121, "Accounting
for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed
Of." SFAS No. 121 requires that long-lived assets be reviewed for impairment
whenever events or changes in circumstances indicate that the carrying amount of
the asset in question may not be recoverable. If an evaluation is required, the
estimated future undiscounted cash flows associated with the asset would be
compared to the asset's carrying amount to determine if a write-down to market
value or discounted cash flow value is necessary. Adoption of this standard did
not have a material effect on the financial position or results of operations of
the Companies.
 
     During June 1996 and June 1997 the Financial Accounting Standards Board
(FASB) issued statement of Financial Accounting Standards (SFAS) No. 125
"Accounting for Transfers and Servicing of Financial Assets and Extinguishment
of Liabilities" and SFAS No. 130 "Reporting Comprehensive Income." The major
provisions of these statements and their impact on the Company are discussed
below.
 
     SFAS No. 125 established criteria for recognition of a sale in conjunction
with the transfer of financial assets, under which sales may only be recognized
when the transferor has surrendered control of the assets. This statement is not
currently anticipated to have any impact on the Company as the Company does not
currently enter into transactions which fall under the scope of this statement.
 
     SFAS No. 130 requires the presentation of comprehensive income in an
entity's financial statements. Comprehensive income represents all changes in
equity of an entity during the reporting period, including net income and
charges directly to equity which are excluded from net income. This statement is
not anticipated to have any impact on the Company as the Company currently does
not enter into any

transactions which result in charges (or credits) directly to equity (such as
additional minimum pension liability changes, currency translation adjustments,
unrealized gains and losses on available for sale securities, etc.).

for certain outstanding loan obligations of various related parties. See Note 11
"Commitments and Contingencies," for discussion of guarantee and security
arrangements provided on behalf of related parties.
 
  Company Indebtedness Guaranteed by Stockholder
 
     The principal stockholder of the Companies has provided personal guarantees
relating to the repayment of long term debt and floorplan obligations incurred
by the Companies. As of December 31, 1996 and June 30, 1997, floorplan
obligations guaranteed by the principal stockholder totaled approximately $32.2
and $20.2 million, respectively, and long term debt obligations totaled

which decrease the fees and commissions paid to the dealerships for the sale of
credit life and disability insurance policies and extended service contracts,
and increase the cost of aftermarket products. The amounts withheld under these
agreements are paid directly to the principal stockholders. Approximately
$675,700, $1,131,500 and $1,591,000 was withheld and paid to the stockholders
under the agreements described above, during the years ended December 31, 1994,
1995 and 1996, respectively.

defaulted loans which have been repurchased by the Companies under a financing
arrangement with a third party lender. (See Note 11).
 
     The Companies have entered into a floorplan agreement with a financing
company owned by the principal stockholder which allows for a maximum of
$1,000,000 in borrowing capacity. As of December 31, 1995 and 1996,
approximately $709,200 and $619,100, respectively, of floorplan notes payable

short term working capital advances to the Companies by the principal
stockholder, as well as for amounts incurred under the financing agreement
discussed previously. Additionally, the Companies have various balances

     As discussed in Note 2, SML is a member of a consolidated group for tax
reporting purposes and reports income taxes under the separate return method.
During 1994 and 1995, SML did not record tax benefits of approximately $184,000
and $585,000 related to net operating losses as such amounts would not be
reimbursed by the consolidated group. During 1996, approximately $323,600 of
these benefits were offset against the provision for taxes and accounted for as
a dividend in the accompanying statement of stockholders' equity.
 
11. COMMITMENTS AND CONTINGENCIES:
 
  Litigation
 
     The Companies are defendants in several lawsuits arising from normal
business activities. Management has reviewed pending litigation with legal
counsel and believes that the ultimate liability, if any, resulting from such
action will not have a material adverse effect on the Companies' financial
position or results of operations.
 
  Insurance
 
     The Companies carry a standard range of insurance coverage, including
general and business auto liability, commercial property, workers' compensation
and excess liability coverage. The Companies have not incurred significant
claims or losses on any of their insurance policies.
 
  Loan Guarantees Provided on Second Chance Financing
 
     The Companies provide second-chance financing for certain customers through
a third party lender. Under the terms of this financing contract, customers
execute installment contracts which are guaranteed with full recourse by the
Companies. The Companies surrender all rights to the future economic benefits
related to the receivables; however, in the event that the customer defaults on
the note, the

lender requires repayment of the principal amount of the note plus earned
interest through the date of default, with repossession of the vehicle to be
performed by the applicable dealership. The Companies do not have the ability to
repurchase these receivables from the lender, and may only be required to
repurchase the receivables from the Lender in the event of default by the
customer. During the years ended December 31, 1994, 1995 and 1996, the Companies
sold approximately $3,518,000, $4,492,000 and $7,471,000, respectively, in full
recourse loans to the lender.
 
     Total customer notes outstanding guaranteed by the dealership at December
31, 1995 and 1996 and June 30, 1997 were approximately $7,413,000, $10,434,000
and $10,190,000, respectively. The principal stockholder of the Companies has
also provided a personal guarantee to the lender related to repayment of these
customer notes. The Companies have provided reserves for future loan losses
based on historical loss trends and total guarantees outstanding.

outstanding with a financial institution as of December 31, 1996, which is
guaranteed by SMT and SML and is secured by all of the real estate, buildings
and improvements at the dealerships. The line of credit expires in January 2000;
however, the agreement contains a provision for two additional five-year renewal

rate plus one and one quarter percent (9.03% at December 31, 1996). As of
December 31, 1996 and June 30, 1997, there was approximately $4.7 million and

2002 (and contains three five-year renewal options) and bears interest at a
variable rate of LIBOR plus 2.5%. At June 30, 1997 there were no amounts
outstanding on the loan. The note was funded during July and a portion of the

12. PROPOSED ACQUISITION BY GROUP 1:
 
     The stockholders of the Companies intend to enter into definitive purchase
agreements with Group 1 providing for the acquisition of the Companies by Group

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To Smith Group:
 
     We have audited the accompanying combined balance sheets of the companies
identified in Note 1 (the Companies) as of December 31, 1995 and 1996, and the
related combined statements of operations, stockholders' equity and cash flows
for each of the three years in the period ended December 31, 1996. These
financial statements are the responsibility of the Companies' management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of the Companies as of December
31, 1995 and 1996, and the results of their operations and their cash flows for
each of the three years in the period ended December 31, 1996, in conformity
with generally accepted accounting principles.

                     NOTES TO COMBINED FINANCIAL STATEMENTS
(All discussions and disclosures with a reference date subsequent to May 9, 1997
                                are unaudited.)
 
1. BUSINESS AND ORGANIZATION:
 
     Smith Group (the Companies) is primarily engaged in the retail sale of new
and used automobiles and the sale of the related finance, insurance and service
contracts thereon. In addition, the Companies sell automotive parts, provide
vehicle servicing and sell wholesale used vehicles.
 
     The following companies are included within the combined group:
 
          Mike Smith Autoplaza, Inc. (MSAP)
 
        MSAP consists of several franchises which conduct business at contiguous
        locations in Beaumont, Texas. The franchises operated in this location
        include Oldsmobile, Lincoln, Mercury, GMC, Mitsubishi, Kia and Honda.
 
          Smith, Liu & Kutz, Inc. (Town North)
 
        Town North consists of three companies operating several franchises
        which conduct business at contiguous locations in Austin, Texas. The
        franchises operated in this location include Nissan, Mitsubishi and
        Suzuki.
 
          Courtesy Nissan, Inc. (Courtesy)
 
        Courtesy is a Nissan dealership located in Richardson, Texas.
 
          Smith, Liu & Corbin, Inc. (d.b.a. Acura Southwest) (Acura)
 
        Acura is an Acura dealership located in Houston, Texas.
 
        Round Rock Nissan, Inc. (Round Rock)
 
        Round Rock is a Nissan dealership located in Round Rock, Texas.
 
     The Companies and their stockholders intend to enter into a definitive
agreement with Group 1 Automotive, Inc. (Group 1), pursuant to which all
outstanding shares of the Companies' common stock will be exchanged for cash and
shares of Group 1's common stock concurrent with the consummation of the initial
public offering of the common stock of Group 1.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
  Basis of Presentation
 
     The accompanying combined financial statements include the accounts of the
Companies listed above. The Companies have been presented on a combined basis
due to their related operations, common ownership and common management control.
All significant intercompany balances and transactions have been eliminated in
combination.
 
  Major Suppliers and Franchise Agreements
 
     The Companies purchase substantially all of their new vehicles from Nissan
Motor Co., Ltd., Honda Motor Co., Ltd., General Motors Corporation, Mitsubishi
Motors Corp., Suzuki Motor Co., Ltd., Ford Motor Company and Kia Motor Co., Ltd.
at the prevailing prices charged by the manufacturers to all franchised dealers.
The Companies' sales volume could be adversely impacted by the manufacturers'
inability to supply the dealership with an adequate supply of popular models or
as a result of an unfavorable allocation of vehicles by the manufacturer.

                                  SMITH GROUP
 
             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
 
     The dealer franchise agreements contain provisions which may limit changes
in dealership management and ownership, place certain restrictions on the
dealerships (such as minimum net worth requirements) and which also provide for
the termination of the franchise agreement by the manufacturers in certain
instances. Under certain state law, these restrictive provisions have been
repeatedly found invalid both by state courts and administrative agencies. See
"Risk Factors -- Manufacturers' Control Over Dealerships" and
"Business -- Franchise Agreements" for further discussion.
 
  Revenue Recognition
 
     Revenue from vehicle sales, parts sales and vehicle service is recognized
upon delivery to the customer.
 
  Finance, Insurance and Service Contract Income Recognition
 
     The Companies arrange financing for customers through various institutions
and receive financing fees equal to the difference between the loan rates
charged to customers over the predetermined financing rates set by the financing
institution. In addition, the Companies receive commissions from the sale of
credit life and disability insurance and extended service contracts to
customers.
 
     The Companies may be charged back (chargebacks) for unearned financing
fees, insurance or service contract commissions in the event of early
termination of the contracts by customers. The revenues from financing fees and
commissions are recorded at the time of the sale of the vehicles. The reserves
for future chargebacks are based on historical operating results and the
termination provisions of the applicable contracts. Finance, insurance and
service contract income, net of estimated chargebacks, are included in other
dealership revenue in the accompanying combined financial statements.
 
  Cash and Cash Equivalents
 
     Cash and cash equivalents include highly liquid investments that have an
original maturity of three months or less at the date of purchase and contracts
in transit. Contracts in transit represent contracts on vehicles sold, for which
the proceeds are in transit from financing institutions.
 
  Inventories
 
     New and demonstrator vehicles are stated at cost, determined on the
last-in, first-out (LIFO) basis, which is not in excess of market.
 
     Used vehicles are stated at the lower of cost or market, determined on a
specific-unit basis.
 
     Parts and accessories are stated at the lower of cost (determined on a
first-in, first-out basis) or market.
 
  Property and Equipment
 
     Property and equipment are recorded at cost and depreciated using the
straight-line method over the estimated useful lives of the assets. Leasehold
improvements are capitalized and amortized over the lesser of the life of the
lease or the estimated life of the asset.
 
     Expenditures for major additions or improvements which extend the useful
lives of assets are capitalized. Minor replacements, maintenance and repairs
which do not improve or extend the life of such assets are charged to operations
as incurred. Disposals are removed at cost less accumulated depreciation, and
any resulting gain or loss is reflected in current operations.

             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
 
  Goodwill
 
     Goodwill represents the excess of the purchase price of dealerships
acquired (Town North Nissan, Courtesy Nissan and Mike Smith Auto Plaza) over the
fair value of assets acquired at the date of acquisition. Goodwill is being
amortized on a straight-line basis over 40 years and amortization expense
charged to operations totaled approximately $67,000 for each of the three years
in the period ended December 31, 1996. Accumulated amortization totaled
approximately $889,000 and $956,000 as of December 31, 1995 and 1996,
respectively.
 
  Income Taxes
 
     The Companies follow the liability method of accounting for income taxes in
accordance with Statement of Financial Accounting Standards (SFAS) No. 109.
Under this method, deferred income taxes are recorded based upon differences
between the financial reporting and tax bases of assets and liabilities and are
measured using the enacted tax rates and laws that will be in effect when the
underlying assets are realized or liabilities are settled.
 
     Certain of the Companies have elected S Corporation status, as defined by
the Internal Revenue Code, whereby the companies are not subject to taxation for
federal purposes. Under S Corporation status, the stockholders report their
share of these companies' taxable earnings or losses in their personal tax
returns.
 
  Environmental Liabilities and Expenditures
 
     Accruals for environmental matters, if any, are recorded as operating
expenses when it is probable that a liability has been incurred and the amount
of the liability can be reasonably estimated. Accrued liabilities are exclusive
of claims against third parties and are not discounted.
 
     In general, costs related to environmental remediation are charged to
expense. Environmental costs are capitalized if the costs increase the value of
the property and/or mitigate or prevent contamination from future operations.
 
  Interest Expense
 
     Automobile manufacturers periodically provide floorplan interest
assistance, or subsidies, which reduce the Companies' cost of financing. The
accompanying financial statements reflect interest expense net of floor plan
assistance.
 
  Fair Value of Financial Instruments
 
     The Companies' financial instruments consist primarily of floor plan notes
payable and long-term debt. The carrying amount of these financial instruments
approximates fair value due either to length of maturity or existence of
variable interest rates that approximate market rates.
 
  Advertising
 
     The Company expenses production and other costs of advertising as incurred.
Advertising expense for the years ended December 31, 1994, 1995 and 1996 totaled
$2,241,055, $2,097,002 and $1,879,591, respectively.
 
  Concentration of Credit Risk
 
     Financial instruments which potentially subject the Companies to a
concentration of credit risk consist principally of cash, cash equivalents,
contracts in transit and accounts receivable. The Company
 
                                      F-61

             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
 
maintains cash balances at financial institutions which may at times be in
excess of federally insured levels. The Companies grant credit to local
companies in various businesses. The Companies perform ongoing credit
evaluations of its customers and generally do not require collateral. The
Companies maintain an allowance for doubtful accounts at a level which
management believes is sufficient to cover potential credit losses. The
Companies have not incurred significant losses related to these financial
instruments to date.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions in determining the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. The significant estimates made by management in the
accompanying financial statements relate to reserves for future chargebacks on
finance, insurance and service contract income. Actual results could differ from
those estimates.
 
  Interim Financial Information
 
     As is normal and customary, the interim financial statements as of June 30,
1997, and for the six months ended June 30, 1996 and 1997, are unaudited, and
certain information normally included in financial statements prepared in
accordance with generally accepted accounting principles has not been included
herein. In the opinion of management, all adjustments necessary to fairly
present the financial position, results of operations and cash flows with
respect to the interim financial statements, have been properly included. Due to
seasonality and other factors, the results of operations for the interim periods
are not necessarily indicative of the results that will be realized for the
entire fiscal year.
 
  Statements of Cash Flows
 
     For purposes of the statements of cash flows, cash and cash equivalents
include contracts in transit which are typically collected within one month or
less. Additionally, the net change in floor plan financing of inventory, which
is a customary financing technique in the industry, is reflected as an operating
activity in the statements of cash flows.
 
  New Accounting Pronouncement
 
     Effective January 1, 1996, the Companies adopted SFAS No. 121, "Accounting
for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed
Of." SFAS No. 121 requires that long-lived assets be reviewed for impairment
whenever events or changes in circumstances indicate that the carrying amount of
the asset in question may not be recoverable. If an evaluation is required, the
estimated future undiscounted cash flows associated with the asset would be
compared to the asset's carrying amount to determine if a write-down to market
value or discounted cash flow value is necessary. Adoption of this standard did
not have a material effect on the financial position or results of operations of
the Companies.
 
     During June 1996 and June 1997 the Financial Accounting Standards Board
(FASB) issued statement of Financial Accounting Standards (SFAS) No. 125
"Accounting for Transfers and Servicing of Financial Assets and Extinguishment
of Liabilities" and SFAS No. 130 "Reporting Comprehensive Income." The major
provisions of these statements and their impact on the Company are discussed

assets. This statement is not currently anticipated to have any impact on the
Company as the Company does not currently enter into transactions which fall
under the scope of this statement.
 
     SFAS No. 130 requires the presentation of comprehensive income in an
entity's financial statements. Comprehensive income represents all changes in
equity of an entity during the reporting period, including net income and
charges directly to equity which are excluded from net income. This statement is
not anticipated to have any impact on the Company as the Company currently does
not enter into any transactions which result in charges (or credits) directly to
equity (such as additional minimum pension liability changes, currency
translation adjustments, unrealized gains and losses on available for sale
securities, etc.).

operating leases with related parties will be restructured under new lease
agreements and the principal stockholder of the Companies will obtain releases
for the Companies from the stockholder loan guarantees discussed above.
