All that will hurt you for a dyed in the wool Mustang owner looking for a CS on resale.
The whole IDEA of the package is that it is unique, special numbering like the other guy said you should have just got a GT Premium - sort of like buying a Cobra and removing the stripes and Cobra badges and putting on 5.0 GT shit.:??:
There is no special numbering on the 11's. Its a stupid 50 cent piece of vinyl and it easily replaced. Get over it. I traded it in anyway. Its just a Mustang GT, nothing special.
