I think this is the way it used to be. My grandfather owned a dealership in the 50's to 70's. It was downtown and had a showroom with three new cars and there were some in the back somewhere. My grandmother drove a "demonstrator" and if someone wanted to test drive that model, they would hunt her down and take her car to be driven. There was a used car lot outside of downtown. That model makes a lot of sense. The dealership doesn't have to pay the carrying cost on a bunch of inventory, worry about hail and a whole host of other issues.
