risk car
n.— «Now a growing number of rental cars are called “risk” cars. Rental companies buy them at a smaller discount and then are responsible for reselling them. “The percentage of program cars (in fleets) two years ago was in the 90s. Now it’s in the 80s,” Barrows said. Avis recently signed a deal that allows the company to sell their so-called risk cars, while they still are operating in the fleet. Rental companies often load them up and send them off to auction. Other firms, such as Enterprise Rent-A-Car Co., sell directly to the public.
