St. Louis, MO and Lake Success, NY – Enterprise Car Sales, a division of Enterprise Rent-A-Car, and DealerTrack, Inc., a subsidiary of DealerTrack Holdings, Inc. (Nasdaq: TRAK), today announced that Enterprise has agreed to implement DealerTrack’s eMenu and DealTransfer® products in Enterprise’s car sale branches across the United States.

Enterprise Car Sales and DealerTrack recently completed a successful 60-day pilot program in 10 branches, and Enterprise plans to implement both products in approximately 100 branches by the end of 2006, with the balance to be implemented early in 2007.

“DealerTrack’s innovative technology solutions allow us to keep our customers better informed, enabling us to enhance our efficiency. Our ongoing compliance efforts are also supported,” said Neal Schroeder, VP, Car Sales Business Administration, Enterprise Car Sales. “With eMenu, all of our locations are presenting all available products clearly and consistently to all customers, while DealTransfer helps us avoid duplicate data entry, speeding up the sales process and reducing errors.”

eMenu enables business and finance managers to consistently present a dealership’s full array of aftermarket product options in a customer-friendly format, simplifying the decision-making process and boosting customer satisfaction. The Final Menu creates an auditable record of the disclosures made to customers, addressing potential compliance risks.

DealTransfer enables dealerships to transfer customer information from the front-end F&I sales management system (Grapevine in Enterprise’s case) directly into the DealerTrack network.

Brad Davies, Assistant Sales Manager at one of the pilot locations in Pennsauken, NJ, noted, “With eMenu, we definitely improved the customer experience and became more efficient.”

“This agreement is an exciting win for DealerTrack and a key endorsement of our products by Enterprise Car Sales, one of the largest retailers of used vehicles in the United States,” said Mark O’Neil, chairman and chief executive officer of DealerTrack.
