CK, did you price the heated seat upgrade, and do you know if the wiringing is in place to add heated seats, I would like to add them to my 400E. As MB DOC stated , the scope of the job is not easy, but if the electrical connections are in place, I going to try to locate a system from a junk yard. I will get many brownie points from the wife!
