If dealers have already agreed to sell the car at MSRP, why should there be any negotiations going on? I can understand if they try to add other things that are not needed and I know that i wouldn't stand for such things myself. For the dealers, you guys have so much ammunition to use against the buyer (by this I mean years of experience doing your job
), I think it would be fair for the buyers to bring some ammo of their own. I don't think that they are trying to tell you how to do your job, they are just trying to get the best deal.
