Hello All Hoping one of you kind folk might be able to help? Would anyone have an idea as to where I might be able to purchase a full set of grey plastic wheel nut caps for a 2008 Sportback? The car is going back to the leasing company soon and I've noticed that the caps have gone a little discoloured due to I think the local car wash using a harsh wheel cleaning fluid (lesson learnt). Would prefer not to go via the local dealer if I can help it? Many thanks !
