HOUSTON, April 30, 2007 — Group 1 Automotive, Inc. (NYSE: GPI), a Fortune 500 automotive retailer, today announced that its wholly-owned subsidiary, Group 1 Realty, Inc., has amended its $75 million five-year revolving mortgage facility and expanded it to $235 million. As part of the amendment, the five-year agreement that was originally entered into with Bank of America, N.A. has been syndicated to include eight additional financial institutions.

The $235 million mortgage facility will provide reasonably priced capital to Group 1 for the purpose of acquiring real estate and buildings in conjunction with its dealership acquisitions and the exercise of selective lease buyout options. The facility also permits the company to move real estate in and out with minor limitations. Lenders in the syndicated facility include three manufacturer-affiliated finance companies – BMW Financial Services NA, LLC, Toyota Motor Credit Corporation and Nissan Motor Acceptance Corporation – and six commercial banks. The commercial banks are Bank of America, N.A.; Wachovia Bank, National Association; Comerica Bank; Sovereign Bank; KeyBank National Association and JPMorgan Chase Bank, N.A. The syndication was led by Banc of America Securities LLC.

“The addition of the syndicate members, with the commitments they have made, validates the strength of our relationships with the lending community and their belief in Group 1’s operations,” said Earl J. Hesterberg, Group 1’s president and chief executive officer.

On March 31, 2007, Group 1 and its subsidiaries held $162.3 million in land and improvements on the balance sheet. The company anticipates acquiring additional real estate in conjunction with its dealership acquisitions, expansion of its existing holdings and the selective exercise of lease buyout options.
