I agree with Ox...I'm 6'4" and you shouldn't be taller than that. I have less than an inch headroom left (no sunroof) and the seat is as far back as possible. I love the car so I don't mind, but long trips might be a problem. I have seen a mod on MZ3.net to tilt the seat a bit, but at 6'7" headroom will remain a problem, even if you have the sun roof. Good luck
