My Up! is on order and I've upgraded to thr sports pack with the Volkswagen Genuine Triangle alloy wheel Wheel size: 6J x 16" Tyre size: 185/50 R16. I'm dreading those beautiful wheels coming with the awful white centre caps. Could anyone tell me what size centre caps I need to replace the white ones with sexy black ones and where to get them? Are they available from VW as a genuine part or are third party ones good enough?
