Speculating, the GT500 may cost approximately $15-20k out the door over what a new Mustang GT costs. Throw some of that savings into a SC and other mods and you still get quite a nice new performing car. Yes the GT500 will be the king of the hill but not everyone can turn over a new car plus mods everytime the king of the hill is replaced. That's why I still have a 99 Cobra verses newer, so I can have my other two vehicles also and not drive the Cobra daily.
