I had the exact same experience in my short test-sit. I am 6' 0" and found that my knee/leg was hitting the steering wheel. Moving to the 911, I was able to get a very comfortable fit by moving the seat the whole way back. I need to go back and re-test the fit before I place an order. I'd swear the first Cayman I sat in was a better fit.

I'll have to try the up and back procedure mentioned by K-Man-sculpture.net when I try it again.

I am going to be VERY disappointed if I can't adjust the seat to a comfortable position. I find the looks of the Cayman far superior to the 911 and am not sure I would buy a 911 if I didn't get a Cayman.
