I'm 6'2", 215lbs. and I didn't think I could find a comfortable position in the Crossfire until a salesman showed me a trick with the power seat. First he lowered it as far as it would go, then he put the seat back in a straight up position. Finally he slid it all the way back until it wouldn't go back any further.
When I got in, I moved the seat forward until my knees were about 1" from the dash board, and then I raised the bottom cushion up in front until it was right where I wanted it to be. Next I tilted the seat back as far as it would go and everything felt great.
There are taller people than me on the forum who have Crossfires, some even with coupes so Redlinedrummer you should be able to find that "sweet spot" if ya play around with the seat adjuster.
For the record, I've spent more than 12 hours straight in my Crossfire and got out feeling like I coud have gone a few more.
