Concept vehicles usually put out larger than life numbers when compared to the car that ACTUALLY goes into production. The cost is also going to put it with the Vipers. One more thing, how expensive and hard is it going to be to modify a V10!? Now another question, how many Z's on this forum alone are already seing those numbers and more with 4 less cylinders? We also spent less money to get there. It is a pretty sweet car, but I think it's losing something...mustangs should have V8's, it's a muscle car not a super car and Ford trying to make it just that. Plus they look pretty good, but not as good as a Z.
