I knew it couldn't be as simple as I thought. We have power headrest, memory and heated coils in a light grey leather. It seems that I read that the SEC seats aren't a good candidate because of the folding backs.
One of the old posts I read last night mentioned Bill H(?) who can make replacement covers and an 800 number for him, I jotted it down. World upholstery seems a bit pricey to me, at least according to their internet price list. We have time, so if we don't get lucky, I'll give Bill a ring.
Thanks for your reply,
