If a dealer has too many used cars, he can't take any more. They only have so much money (or credit line) that they can use for the used. Dealer would rather retail a used than wholesale, for obvious reasons. Also, no MSRP on used, they can price them at whatever they want. Salesmen often make more on a used car sale than new. (Everyone knows anymore what is invoice on a new car, but are clueless as to what the actual amount a dealer has in a used car)
