                    Quarter and Six Months of 2003


    HOUSTON--(BUSINESS WIRE)--July 31, 2003--Group 1 Automotive, Inc.
(NYSE:GPI), a Fortune 500 specialty retailer, today reported record
second-quarter net income of $20.0 million, or $0.86 per diluted
share, on record revenues of $1.1 billion for the three months ended
June 30, 2003.
    "Our solid second-quarter performance demonstrates the flexibility
of our business model," said B.B. Hollingsworth Jr., Group 1's
chairman, president and chief executive officer. "Facing a slightly
less robust automobile retail environment, we dealt with declining
vehicle sales and delivered earnings growth and gross margin
expansion. This quarter's performance keeps us on track to achieve our
goal of growing earnings per share for the sixth consecutive year."

    Second-Quarter Highlights:

    --  Diluted EPS increased 10.3 percent to $0.86

    --  Revenues increased 11.1 percent to $1.1 billion

    --  Parts & service revenues increased 21.7 percent

    Results for the Second Quarter

    During the second quarter, revenues grew 11.1 percent to $1.1
billion from $1.0 billion during the same period last year. As the
overall automobile market declined, same store revenues fell 5.1
percent, compared with a 1.3 percent decline in the second quarter of
2002. Revenues contributed by dealerships acquired by the company
during 2002 and 2003 offset this decline.
    New vehicle retail sales expanded 12.7 percent, on a unit sales
increase of 8.4 percent. Used vehicle retail sales rose 0.1 percent,
with retail unit sales 0.3 percent lower. Parts and service and
finance and insurance revenues grew 21.7 percent and 18.2 percent,
respectively.
    Gross margin for the quarter increased to 16.0 percent compared
with 15.6 percent during the year-ago period, as revenues increased in
each category and the company benefited from rapid growth in its
higher-margin parts and service, and finance and insurance businesses.
Income from operations was $40.3 million versus $37.2 million, an 8.4
percent increase. Operating margin was 3.5 percent compared with 3.6
percent during the year-ago period.
    Net income increased 4.4 percent to $20.0 million from $19.1
million, and diluted average shares outstanding decreased 5.0 percent
to 23.3 million. Diluted earnings per share grew 10.3 percent to $0.86
from $0.78 a year ago.
    Hollingsworth noted that from a brand standpoint Lexus, Infiniti
and Honda were among the strongest performers. "We had outstanding
performances from our Los Angeles and Boston platforms," he added.

    Solid Performance for Six Months

    For the first six months of 2003, revenues reached $2.2 billion, a
10.0 percent increase from $2.0 billion for the same period last year.
Same store revenues fell 6.4 percent, compared with a 0.7 percent
decline in the first six months of 2002.
    New vehicle revenues grew 10.2 percent on a 7.6 percent increase
in unit sales. Used vehicle retail revenues rose 1.7 percent on a
retail unit sales increase of 0.3 percent. Parts and service and
finance and insurance revenues grew 21.5 percent and 18.0 percent,
respectively. Diluted earnings per share increased 5.6 percent to
$1.50 on net income of $34.8 million, compared with $1.42 per diluted
share on net income of $34.6 million, for the first six months of
2002.
    Year-to-date gross margin increased to 16.2 percent compared with
15.8 percent in the 2002 period. The shift in merchandising mix that
impacted gross margin in the second quarter had a similar effect on
the six-month period. Income from operations rose 3.9 percent to $71.7
million from $69.0 million, and the operating margin contracted to 3.3
percent compared with 3.5 percent last year.

    Recent Developments

    Group 1 also reported that in July 2003 its Dallas platform
completed a market consolidation in conjunction with DaimlerChysler's
Alpha Initiative. The transaction resulted in the consolidation of
three dealerships consisting of four franchises into one 100,000
square foot dealership housing Dodge, Chrysler and Jeep franchises.
This initiative is expected to result in improved operating leverage
and increased sales in the company's Dallas operations.

    Management's Outlook

    Group 1 expects a solid vehicle market for the balance of 2003,
although volatile at times and less robust than 2002. Based on recent
financial performance and excluding the impact of the recently
announced debt offering, the company confirmed its previously
announced range of diluted earnings per share guidance for 2003 of
$3.10 to $3.30. The impact of the proposed debt offering will depend
on its terms and timing of subsequent funding of investments. Based on
current market conditions and the net funds raised in the proposed
offering being temporarily used to pay down short-term debt, the
offering would reduce 2003 diluted earnings per share by approximately
$0.10. Earnings-per-share growth is expected to emanate from a
combination of dealership performance and acquisitions, as well as
common stock repurchases, as warranted. During the last 12 months,
Group 1 repurchased 1.1 million shares of its common stock at an
average price of $23.83. As of June 30, 2003, the company had
remaining board authorization to repurchase $22.5 million of its
common stock.
    Group 1 continues to seek additional strategic tuck-in
acquisitions to augment its current markets, as well as platform
acquisitions to enter new markets, targeting to add dealerships with
aggregate annual revenues of approximately $800 million. Year to date
the company has acquired three franchises with estimated annual
revenues of $131.2 million. Hollingsworth stated, "Group 1's stable
cash flow from operations, combined with one of the strongest balance
sheets in the industry, allows us to take advantage of opportunities
to make investments that enhance shareholder value."
