If ford could make you a brand new mustang, didnt cost anything, no matter what options what would it be/look like? If they could be built, even with lack of common sense, what would you have them do?

What body would you choose? (94-98, 99-04, 05-09, etc)
What body style? (coupe, hatchback, convertible, etc)
What color? (rio red, candy apple red, something other than red etc)
What kind of engine? (you say LS1, I'll slap you!)
Performance upgrades? (factory and non factory)
Appearance mods? (factory and non factory)
Factory and non factory options. (automatic in a cobra r, or heated seats in a 64, etc)
What kind of interior? (leather/cloth, color, 64 interior in an 05 )
Any specific special edition/builder? (indy, foose, roush, mach, cobra, shelby, etc)

Any Mustang at all!??

It would have to be a custom '70 sports roof (fastback). Smoothed and shaved body including drip rails, door handles, and seams.  Bumpers would be smoothed and modified to sit tighter to the body.  Also a custom carbon fiber cowl hood with heat extractor vents, custom carbon fiber rear air diffuser and under body panels to aid aerodynamics.  All painted a metallic white pearl. The only chrome will be the bumpers and wheels.
