Id go with red! My mini is gray with red I wouldnt have it any other way. Always had black or gray interiors so I was happy to get some color. If I could choose I would have a color on all colorless cars. Black white or gray car and a colored interior always looks better more classy and happy. Im always thinking of doing my black 911 tan or red but I dont want to fix what isnt broken just making more work for myself.
