Misfit41: Most of the difference is in the suspension components. Shelby uses their own custom stuff.
All in all they are pretty much identical when the cars are finished. Kinda like the difference between a CSX 3000 and an original COB Cobra (English AC Cobra). Except today its CSX and KMP.
Dan: Happy mothers day to you too!
BTW why don't you upgrade to peddle power. It would be a nice mothers day gift!
