I am 6'5, and ashamed to say I weigh too much for my frame, however, I absolutely love my SSR. I drove it up to the Woodward Dream Cruise, and even though my wife kept checking in with me to see how the drive was going, I would probally do it again.
The drive was great, and yes I had plenty of leg room, getting up early in the morning to get a jump on traffic, dropping the top, and crusing until 10:00a. - 10:30a. until my first stop and put the top back up as the day heats up. I ran it at about 70 - 85 the whole way up, (except when I was following the "Ding" :lol )
I kept the a/c at 2 - 3 and loved it. I betcha you will love it too. I met lot's of great people. The sights, the sounds, the feeling of communing with other SSR nuts, LOL, Seriously, The SSR is a great looking truck, car or what ever else you want to call it.
I think when I drove around with my wife's uncle in the car sums it up very nicely; "Do people always stare when you are driving around?"
