Mrs 13156 just had the wheels on the CLK (her pride and joy) refurbished a couple of weeks ago. In order to finish the job I ordered a new set of shiny silver and blue centre caps. I was just popping the last one into the rear nearside when I noticed that she had kerbed it. It's not that noticeable unless you're fairly close, but she's scraped the lacquer, paint and powder coating off to bare metal across 9" of the rim. Probably done it reversing into a parking spot at work which is known to have 9" high granite setts. Sigh!
