Some car dealers have installed private car washes. Come in for a free wash, any time, as long as you own the car and are displaying the dealer plate. So at least in that case they're "paying" for the advertising.

Lol good way to get someone who buys cars from dealers to come back.

This I wouldn't mind - a car wash is a high markup item just like advertising, and both sides would get something out from the deal.
