HOUSTON, Aug. 3, 2007 — Group 1 Automotive, Inc. (NYSE: GPI), a Fortune 500 automotive retailer, announced today it is further consolidating its U.S. operating regions from four to three to streamline management and gain additional efficiencies.

Effective Sept. 1, Group 1 will realign its U.S. regional management responsibilities by combining its current Northeast and Southeast Regions into one Eastern Region that will be overseen by David W. Hult. Hult has 22 years of retail industry experience that includes significant success operating Toyota and Lexus dealerships. Toyota and Lexus represented 36 percent of Group 1’s new vehicle unit sales in the 2007 second quarter.

Martin E. Collins, currently regional vice president of the Southeast Region, will relocate to California to lead the renamed Western Region as regional vice president. Collins, who joined Group 1 after a 20-year career with Ford, will succeed David L. Hutton, who has elected to retire effective Sept. 1. Frank Grese Jr. will continue as regional vice president of Group 1’s Central Region.

In addition, the company’s six U.K. franchises will continue to operate under the guidance of Ian Twinley.

“We have four exceptional automotive-industry veterans in place who are focused on stimulating organic growth in our operating units that span from California to the United Kingdom,” said Earl J. Hesterberg, Group 1’s president and chief executive officer. “By streamlining our management structure, we can further accelerate the standardization of best practices while remaining sensitive to local market issues.”

Regional Vice President Retirement
Hutton will transition from his current role into a consulting position effective Sept. 1. Since January 2006, Hutton led the West Region consisting of 12 import and domestic dealerships located in California. An integral part of Group 1’s growth, he joined the company as platform president of the Miller Automotive Group when it was acquired by Group 1 in August 2002.

“Dave Hutton’s outstanding leadership and solid reputation in the industry have contributed greatly to Group 1’s success,” said Hesterberg. “We thank him for his dedication and ongoing commitment as an invaluable consultant to Group 1.”
