I'm 24, and have eight cylinders under the hood.
Unlike xspeed02's mother, when i'm 49, i hope to be at twelve cylinders

(all due respect to y're mum)
Again, it all boils down to money. The accountants won't approve a muscle car for production with decent ergonomic's. The only good part left is power, and the consumer has to pay through the nose for it. Not many can, that's why they sit for ever on the dealer lot's.
IMO for the new 'Stang,
Seating, ditch the dining room style seats. Maybe next year Ford can use the left over F-Body bucket's?
Shifter, move the shifter about 1 foot back. I'm amazed how they can get away with a shifter that's terribly misplaced as it is. I'm like the hunch-back of notre-dame, shifting his way home.
Power. 300HP wouldn't hurt. A functional hood scoop would be good. Maybe borrow the WS6 idea from the defunct f-body?
Options. How about getting peoples blood pumping (and NOT charge an arm and a leg) for an optional "Drag Package", with special emblems identifying it as such. You know, 4:10 gearing, special exhaust, traction bars w/subframe connectors, Bear brakes.
Oh yeah, and lowered from the factory by 8 inches.
Yup, that sounds like what a muscle car should be
