I'm freakin huge.
6' 2", 290lbs. I do wish the seat was an inch or so shorter, but I've still got about an inch and a half of head room (I'd have another two or so inches if I didn't have a sun roof) and plenty of room in the shoulder/hip area. Overall, I'd say it's less cramped than my last vehicle, where my legs were almost hitting the kick panels on the dash. It would be nice if the steering wheel adjusted upwards a tiny bit more, and had a telescopic feature to bring it a little closer, but pretty much
every vehicle I've driven is like that.
It may seem more cramped if I wore a heavy jacket, but I haven't had to do that yet.
I wouldn't call the cabin particularly
spacious, but for the vehicle size it's pretty good. I was impressed that there was one more inch of rear knee room behind the driver's seat than my previous vehicle, for passengers. Although I do have to remove the head rests to get the seats folded down.
