Well a few issues ago the Mach 1 was the cover story for MM & FF, and it out performed the 01 Cobra times even with the automatic version. The magazine went out of its way to mention this
I don't know all the differences between the Mach 1 and the GT, but I do know that the Mach 1 is DOHC and has 03 Cobra Heads. For slightly less than $30K (same price as my Cobra brand new) you can get a 5 speed that is faster than the 01 Cobra I don't think that's expensive at all. In addition the car itself is very impressive looking inside and out.
