Yeah, I feel like the last salesmen I just bought my new mini-van from would never work with me again. Half way through negotiation I ask him to bring the manager of the whole place by so I can just negotiate with him instead. He was not a fan of that, but I did get 8,000 off (negotiated high trade-in value too). He did not talk to me much after the manager and I shook hands, but the manager was the one to approve price drops so the salesmen seemed worthless to me.
