I'm 6'1" and if I put the seat all the way back I don't think I would be able to reach the steering wheel. Unless the seat back would be straight up! or even forward, which I HATE.
Keep in mind, torso length. It's not just leggs that make the overall height.
Someone with a short torso could have longer leggs than a shorter person.
Two people with the same overall height can have leggs quite different in length.
