That is what I had feared! I did not want to make it to fit me specifically as I am a short 5' 8" and that means other people can't enjoy getting in it and trying it on for size at shows. I really wanted it to be more adjustable. What if I modified the entire floor to drop down slightly at first, with a little more slope as it went back? Obviously I would not drop it to low for clearance issues, but then the seats could be easily adjusted! And the taller you are the more head room you would get as you push the seat back?!
