Note that car dealerships are like that because the dealership cannot offer you the later. You go into the dealer having looked up their cost on Edmunds/kbb/... and are determined to give them zero profit from the sale. Worse you know (right or wrong) what you want to buy and so they can't even provide the service of listening to your needs and getting you in the right car.

In theory you should have better luck by walking in and saying I'll pay MSRP (thus giving them a reasonable profit) if you don't add all that other BS. In practice they won't know how to do that because nobody else does
