While I would normally tend to agree with most responses concerning the purchase of a GT from a reputable Ford dealer, I, like Tom, have also purchased a GT from Bently Long Island in Jerico New York.
I really had no problems with the purchase and was able to pick up the car for about 2K over MSRP. Monies were wired to them on Feb 8th but the car did not arrive IN Platteville, WI for about 3 weeks. Turned out it was not Bently Long Island but the transport company. About the time of the purchase there was a pretty bad winter storm in the area and they waited for a fairly long time to get the car out to me.
It really didn't matter since I had hip replacement on Feb 9th and it would be about a month after receiving the car before I was actually able to sit in it for the first time. For a couple of weeks I spent lots of time in the garage drooling! First time I got into it I took it out on the interstate and got it up to 150 mph ... but I digress.
Bottom line: I had no problems with my purchase from Bently Long Island in Jerico, NY. The car still had the plastic wrap on the inside, steering wheel, etc. and had a total of 38.6 miles on it. Given my experience with them, I would most likely purchase another car from them if they had exactly what I wanted.
