I'm going to be buying wheels in the next few weeks but at the moment I can't decide what to get. I Know I want 18's but do I go for the RS6 replicas or diamond cut A8 replicas? I think the A8 wheels look great but I also think they are better suited to darker cars. I like the idea of the RS6 wheels as I have 5 spokes on there now and think they suit the car well. Any ideas?...
