I ain't that big or small (5'9" and 190lbs) but I can't complain where it matters most 8). Seriously I have found my rex very comfortable since over 15 yrs and I can still get in and out of it fairly easily.
I'm almost 5'10", and about 210lbs, but that changes all the time. It's nice not having to worry about bumping my head going over bumps like some of you other guys. I don't have the seat all the way forward but I don't put it all they way back, gansta style either. I actually think the CRX is roomier than my 96 Civic.
