I replaced my worn armrest and shift boot with new pieces from redlinegoods.com. They are done in Charcoal and Light Grey to match the two-tone door panels, with triple stitching in the BMW Motorsport colors. Just a minor cosmetic mod, but it really nt up the interior. I also painted the wood trim panel above the glovebox with Plasti-dip spray. It gives a nice OEM looking rubberized finish, but I can peel it off whenever I want if I decide I want the wood back. Pretty neat stuff for $6 a can. I also used it on my kidney grills up front.
