    Results for the Third Quarter

    During the third quarter, revenues grew 3.1 percent to $1.24
billion from $1.20 billion during the same period last year. As the
overall automobile market declined, same store revenues fell 4.7
percent, compared with a 4.1 percent increase in the third quarter of
2002. Revenues contributed by dealerships acquired by the company
during 2002 and 2003 offset this decline.
    Hollingsworth noted that from a brand standpoint Lexus, Infiniti
and Honda were among the strongest performers. "We had outstanding
performances from our Los Angeles, Boston and Austin platforms," he
added.
    New vehicle retail revenues expanded 4.5 percent, on a unit sales
increase of 1.7 percent. Used vehicle retail revenues declined 9.5
percent, with retail unit sales 9.2 percent lower. Parts and service
and finance and insurance revenues grew 12.5 percent and 8.9 percent,
respectively.
    Gross margin for the quarter increased to 15.7 percent compared
with 15.0 percent during the year-ago period, as the company benefited
from rapid growth in its higher-margin parts and service, and finance
and insurance businesses, as well as a $0.4 million decrease in the
new vehicle valuation reserve resulting from a reduction in new
vehicle days supply. Income from operations was $42.9 million versus
$40.1 million, a 7.1 percent increase. Operating margin was 3.5
percent compared with 3.3 percent during the year-ago period.
    Net income increased 7.7 percent to $21.7 million from $20.1
million, and diluted average shares outstanding decreased 1.7 percent
to 23.6 million. Diluted earnings per share grew 9.5 percent to $0.92
from $0.84 a year ago.

    Solid Performance for Nine Months

    For the first nine months of 2003, revenues reached $3.4 billion,
a 7.4 percent increase from $3.2 billion for the same period last
year. Same store revenues fell 5.9 percent, compared with a 1.0
percent increase in the first nine months of 2002.
    New vehicle revenues grew 8.0 percent on a 5.4 percent increase in
unit sales. Used vehicle retail revenues fell 2.4 percent on a retail
unit sales decrease of 3.1 percent. Parts and service and finance and
insurance revenues grew 18.2 percent and 14.6 percent, respectively.
Diluted earnings per share increased 7.1 percent to $2.42 on net
income of $56.5 million, compared with $2.26 per diluted share on net
income of $54.8 million, for the first nine months of 2002.
    Year-to-date gross margin increased to 16.0 percent compared with
15.5 percent in the 2002 period. The shift in merchandising mix that
impacted gross margin in the third quarter had a similar effect on the
nine-month period. Income from operations rose 5.1 percent to $114.6
million from $109.1 million, and the operating margin remained stable
at 3.4 percent.

    Recent Developments

    During the third quarter, Group 1 acquired Dodge, Lincoln-Mercury
and Mitsubishi dealerships in the New Orleans area. The dealerships
will operate as part of the Bohn Automotive Group platform and are
expected to add approximately $110.0 million in aggregate annual
revenues. Year to date, the company has acquired seven franchises with
estimated annual revenues of $241.2 million. "While we may close
additional tuck-in acquisitions this year, most of the transactions
that are currently in process will not close before 2004," said
Hollingsworth. "With 22,000 dealerships in the United States, there
are ample acquisition opportunities that meet our criteria," he added.
    Additionally, Group 1 expanded its brand diversity with Toyota's
launch of Scion. The Scion brand operates under the Toyota Motor Sales
marquee and is focused on trend-setting youthful buyers. Scion began
its initial rollout in California in 2003 and is expected to expand
geographically during 2004. Group 1 anticipates selling Scion in all
nine Toyota franchises currently operated.

    Management's Outlook

    Group 1 expects a solid vehicle market for the balance of 2003 and
for 2004. Based on recent financial performance and including the
dilutive impact of the recently completed debt offering, the company
expects diluted earnings per share for FY2003 of $3.05 to $3.15.
Additionally, excluding future acquisitions, the company expects
diluted earnings per share of $3.10 to $3.30 for FY2004. If Group 1
redeems its 10 7/8% bonds in March 2004, as expected, it will incur a
one-time after-tax charge of approximately $4.1 million or $0.17 per
diluted share. Management's 2004 earnings guidance does not include
this one-time expense.
    The company continues to seek additional strategic tuck-in
acquisitions to augment its current markets, as well as platform
acquisitions to enter new markets. With the carryover from 2003, the
company is now targeting to add dealerships with aggregate annual
revenues of approximately $1 billion in 2004.
    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."
