I'm 6'3" and I have my driver's seat at its lowest position - this suits me fine (granted, I don't wear a helmet on the way to work), but I hate being the passenger when my wife is driving - no, she drives fine (better than I do) - because I feel like a giant in the passenger seat - my head occassionally hits the ceiling.
Consider me interested since day one of ownership.
