Hmm that's probably a wrecking-yard type thing. How is it looking bad? Damaged? Split? You could take it off and paint it yourself almost. It's nothing too hard to get a nice finish on, a thin and small surface area.
If it is damaged, it could be fairly easy to repair... It is plastic isn't it. Plastic filler and alot of patience
I have seen one set of them come up on ebay a few months back (Australia) and the guy wanted the earth for 'em.
