I'm a little hesitant to admit that I spent some time in a Ford Dealer looking at a GT500...I had some time after work one day.
They had a '12 Shelby listed for 55,000 with the Recaro seats and the SVT pack. They were willing to take 1000 off the price, whereas the Boss LS inside had a 10,000 adjustment bringing it to 55 and some change...
