Always fancied a set of centrelocks, but re colour, the standard alloys on my Plus 8 are painted BRG to match the body, and I think the car looks great - but then I would say that wouldn't I !!!
So how about taking the opportunity and changing the alloys to red to match the upholstery ? Could look good with the BRG bodywork paint; I can only just about handle Photoshop but can anyone offer a CGI preview of that ?
