From all accounts, it seems as if the Z is designed with larger drivers in mind. There have been several reports of people of your dimensions being very comfortable in the Z.

 

I'm 6'3" and 205 lbs and had no prob. head room is usually an issue with me but the Z had pleanty. There have been a lot of people larger than you that say they fit. It will be up to you to judge.

Could you give us any indication of other cars you fit in or have problems and what type of problems? For example I drove an NSX and my head was actually touching the roof. I sat in a Z06 twice and had at least an inch less headroom than in the 350Z. I still fit in the Z06, but I knew the roof was not far away.

 

I'm 6'3" and 270. I fit, but just barely. I didn't like the front view until I changed the angle of the seat, I had the seat all the way back and had PERFECT leg room, but obviously if I was a little taller, I would have been cramped. I was VERY slightly cramped through the soldiers, with my left arm at my side, but since I will be having that arm when on the wheel I should be fine. Considering my large size, I would have to say Nissan has done a pretty good job of accomodating large drivers.

 

sat in it today, im 6 foot 3 230 and had a ton of room.......head room is super.

 

Seen a guy at Z-Fest sit it it. He was
6'7" and still had head room.
