UNITEDAUTO REVENUES INCREASE 20%
____________________________________________________________

Results Include $0.03 per Share of Severance Charges
___________________________________________________________

BLOOMFIELD HILLS, MI, July 19, 2005 – United Auto Group, Inc. (NYSE: UAG), a FORTUNE 500 automotive specialty retailer, today announced its 25^th consecutive quarter of record revenues and a 25 basis-point improvement in gross margin to 14.8%. Total revenue increased 20% to $2.7 billion, including a 7.2% increase in same-store retail revenue. Same-store highlights include:

Net income for the quarter was $33.2 million, or $0.71 per share and included $1.2 million ($0.03 per share) of after-tax severance charges as UnitedAuto rationalized its cost structure in certain markets. Second quarter 2004 net income was $33.0 million, or $0.71 per share, and included a $4.0 million ($0.09 per share) after-tax gain resulting from the sale of an investment. Excluding the impact of the severance charges and the gain from investment, adjusted net income increased 18.8% to $34.4 million from $29.0 million in the prior period.

Roger Penske, UnitedAuto Chairman, commented, “We are pleased with the revenue growth and margin expansion we realized across each of our product lines during the second quarter. We continue to achieve impressive growth in our higher margin service and parts departments due, in part, to our capital investment program. Total service and parts revenue increased 22.3% to $281 million in the quarter, helping to drive our gross margin increase.” Penske continued, “Our strong sales performance and focus on managing inventory resulted in a 55-days supply of new vehicle inventory in the U.S. compared to a 67-days supply for the U.S. auto industry.”

Commenting further Penske said, “The Company is currently projecting earnings per share in the third quarter in the range of $0.66 to $0.71 based on an estimated average of 47.2 million shares outstanding. For the full year, we are raising our earnings per share guidance to a range of $2.37 to $2.44 per share.”
