Re: How tall are you guys??
6 feet here and about 210. First time I got in I said no way - not because there wasn't enough head room (leg room in these cars are great), but becasue I was used to a much larger cabin. The limited seats are power and adjust up-down and every which way you want. Once you find your zone, it's damn comfortable -- and plenty of head room. Like others have said, drive one for a while. Once you do, it will feel very room. Other sports cars I have been in fell more cramped and frankly nowhere near as comfortable.
Bottom line, if you are 6 feet or in that range, head and leg room isn't and issue.
Good luck.
