I am 6'1 and have a 5, it is alright to drive, but a little snug trying to get in it. My uncle has a cj7, and it is much roomier. Another good thing about the 7's are that most year models are wider and longer than the cj5, which, if you are going to want an rock crawler, would be better. But either one is a great vehicle to drive. Good luck.
