I called the Ford Performance Group at 1-800-367-3788. They ask for the last six numbers of your vin. My last six are 309456. So... out of 8,150 GT500 coupes mine is 5,202. For white coupes Mine is 1,313 . It only took around two minutes on the phone and it is free ! TOM
I did the same today. Forget the numbers but mine was in the last 300 or so made for 07. Built June 8. For $45 they send a cert of authenticity and some other info. Kind of a rip, but I did it anyway. Rarest 07 is a Vista Blue with stripe delete. Only 9 made. They don't break it down by options.
