I'm 6'4"/200 lbs., also tall in the torso - love the car. Not a lot of extra room, but it's a comfortable driving position, even when I'm in the car for a while. The one drawback is the yardstick test for track days. The local track is lenient (one of the few) and lets me drive DE with the stock bars. I'm considering a BK extension so I can get into more tracks. But on the road - no problems. Certainly bigger than the Miata I had before
Search the threads - I think some people have found aftermarket seats that are thinner and sit in the floor - giving an extra inch or so headroom. Racing seats may not provide touring comfort, though.
