Shop around, I have helped buddy's get a few deals by going to a few dealer ships, telling the salesmen flat out, your going for the 2012 rubicon in this color, these options, and going to who ever gives the best price, all salesmen want their commission and generally do what ever they can to make the sale, also once in a while sales men will say go some place else then too,
My mom almost bought a 2011 mustang last year, we went to Marlborough ford, they didn't want to play ball. Universal was doing just about everything they could to make the sale, but in the end she didn't like the trade in and such, but shop around, see who plays ball, and go with them, no one likes ball hogs.
