This is more based on a car commercial I saw so not sure how accurate the law is. I had the impression the buyer had this to me weird right to know how much the dealer bought the car for. That would go well beyond that IMO. Say someone at the dealer won a free car and wanted to turn around and sell the thing for however much profit they wanted to make, I'm not seeing where the issue is? If the buyer is still getting a great deal on it, well..... at times it seems to me it's about paying little as possible for something than consumer protection.
