I am in the negotiating process for a 2008 Shelby GT convertible with approximately 30K miles 5 speed in really clean condx. Does anyone have a "good feel" as to whether or not a $29K asking price is high, low, or average?? I have previously owned two other Mustang convertibles, most recently a 1990 limited Ed 25 anniversary model which was destroyed in Hurricane Ivan at the end of '04. BTW, my other car is a first owner Corvette 1997 C-5. Great vehicle, but love the Ford Big Block ponies, especially the "Sound of high Revs"! thanks for any comments.
