I didn't know some people had an issue with the seats. Hubby took his sixty from NJ to NC and back as a solo driver and said he was VERY comfortable.
I don't find the seats uncomfortable (although they are a bit hard). My problem with them is that my P85+ has quite impressive handling capabilities, but I need to hang on to the wheel for dear life whenever I take a turn. The seats have the lateral support of a bench seat out of a '59 Cadillac.
