After driving a Z06 I never ever thought about owning a Cobra again. Only mustang I'd own is a vert for cruising w/ 4 people or a track bitch notch from FlimFlam @ PAS.

You sit in a Z06/C5/C6 whereas you sit on a mustang... the ergonomics of the Vette as far as steering wheel and shifter position are far superior.

If you want a badass drag car get the KB car and put a stick axle in it. If you want a better all around car keep your Z.
