Took an hour of negotiating and tears from my fiance about me ready to walk to get an army green at msrp here in Colorado few weeks ago. I told them Mountain States toyota would sell me one at msrp and I would go there and they went from 5k markup to 2.5k markup to 1k markup to msrp after a couple late night phone calls to SM and GM. They told me "congrats, no one has ever got a pro at msrp here let alone the special color, don't tell anyone."
Autonation guy was bragging to me about how they were selling them at 10k over which I thought was a weird move to a potential customer.
Definitely tough to negotiate though, they know they would have no problems selling to the next person at markup here in Colorado.
