6' 6" here, 36 inseam. I fit in the 8 just fine, but only if it has no sunroof.
Oh, and nobody can sit behind me because my seat is pushed all the way back in it's track.

 

6' 3" here and I have no problem without the sunroof and the seat pushed down and back. I did notice it was a bit more cramped in the passenger seat where you cant push it down any. Also, no one can sit behind me really unless they are pretty small. Sometimes I try to move my seat up to allow room for them but its quite difficult lifting off the clutch like that and makes for a jerky ride.

 

6'5 with 36 inseam WITH sunroof and I manage to fit.

I do have the seat all the way down and reclined quite a bit but it's a small price to pay to drive this car. I don't ever see myself being able to drive with a helmet but thats okay since I don't plan to do any track time in this car.

Anyone else rub their hair when they turn their head to the left to look out the small back window? (blind spot checking) Funny design on that part of the headliner as it stick out and down a bit...
