Just to play devil's advocate... But wouldn't a car dealer try to have a variety of cars models instead of multiple cars of the same model? Wouldn't it be better for them to be able to show a potential customer a variety of cars rather than just one model? For example, if they could only have 3 cars, wouldn't it make more sense for them to have an A4, a BMW 3, and an Acura TLX (for example) rather than 3 A4s? Or maybe used car dealers have significantly more stock than I'm giving them credit for?
