Enterprise Holdings is a privately held company formed in 2009 to operate three rental car subsidiaries: Enterprise Rent-A-Car, National Car Rental and Alamo Rent A Car, along with WeCar (the company's carsharing company), and its commercial fleet management, used car sales, and commercial truck rental operations.

Enterprise Rent-A-Car is the largest rental car company in North America, and has more than 5,399 “local market” locations (91% of all transactions), and 419 airport locations (9% of all transactions). According to Detroit News, Enterprise purchases seven percent of all new automobiles sold in the United States.

Enterprise Rent-A-Car’s primary focus is the local rental car market, specializing in car rentals to consumers who need a replacement car as the result of an accident, mechanical repair, theft, or who require a vehicle for a special occasion such as a short business or leisure trip. In the late 1990s, Enterprise Rent-A-Car also began expanding its operations to include the airport market, and now serves airports in the United States, Canada, the UK and Ireland.

By 2005, Enterprise Rent-A-Car's customer service has been recognized seven times by J.D. Power and Associates as highest in customer satisfaction for rental car companies at or near airports. The company was named ninth on Business Week's top 25 companies customer service list in 2007.
