The cars sell themselves, but the salesmen may steer you one way to another when the choices are close.
My Infiniti salesman was fairly knowledgeable, but he would not make a deal until I did some research to prove that I can get a better deal elsewhere. He knows little about the accessories, prices were wrong, and he had no idea if they are in stock until you order them. He is not very honest about the prices (made up stories) and the car took a lot longer to arrive than he promised.
