I got $3,691 off MSRP on my GT Premium. MSRP was $40,805 with options. Sale price was $37,114
out the door was $41,313 (inc. 7.95% sales tax, registration, doc fee, etc.)
My strategy was to search inventory online of all dealers within a 200 mile radius (max distance I was prepared to drive). I wanted a GT Premium with the performance pack and a few other things. Then I contacted the internet sales manager for each dealer that looked promising. Then I played some of them off against each other a little. But to be honest, the one that I went with in the end gave me this price right up front with no games at all. It was Chapman Ford in Scottsdale if anyone is interested (internet guy is Tate Wetzel).
I would be interested to know what kind of deals people got when ordering from the factory. I kind of wanted to do that myself but 1. I am too impatient to wait for the build and 2. I somehow doubt I would get as good a deal. Not sure if that's true though.
