Find a car and test drive it. Fiddle with the seat. There are several members who are less active and they are much taller than the posters here. Matter of fact, Rudy who is now with Speedriven is well over 6'0 and over 250 and he had an SRT6 for some time period. Ray who is OSOFAST2 is well over 6" as well.
The thing to remember the first time you get in the car it will not be comfortable. Set the seat back as far as it will go with the seat back up. Then adjust the seat to where you are comfortable remember you have six directions of movement. Then bring the wheel in for the sweet spot.
