I have a line on a pair of E36 M3 "Vader" seats and headrests. Light/Dove Gray with 3 M colors. Driver and passenger. Price is less than dealer cost. Email me if you are interested.
I do not have the seats... my parts guy got stuck with them after a snotnosed kid ordered them and backed out. I'm doing him a favor by posting.
These will not fit the Z3 cars. Dunno if they fit E46.
