SilentShooter welcome to the forum.
I'm 6'2" with a 32" inseam, 215lb. and I fit in my 04 coupe just fine. I've been in the drivers seat for over 12hrs. more than a few times, (stopping only for gas, food, and rest stops) and never got out with any aches or pains.
The trick is playing with the seat adjuster for a few minutes to find the previously mentioned "sweet spot" and that's all it takes.
Roadsters offer a little more head room, and some people think the Base cars cloth seats offer more head room as well.
I think there are more than a few coupe owners that are 6'3" tall, so at 6', you should be good to go.
Try to find one closer to home just to sit in. Heck there's probably a forum member that lives close by, and would be glad to let you give it a try.
I purchased mine sight unseen, thinking I was going to have to get a "custom" seat for it. But when I picked it up new at the dealership the salesmen showed me the trick with the seat adjuster, and I drove 9 hrs straight home without a cramp.
