I got round the "hubcaps falling off" thing by replacing them with Peugeot alloys off eBay
The hub caps that were on my car when I bought it were the tattiest bit on the whole car.
Nearly 2 years later, that "honour" now falls to the bit of black rubber window trim on the rear drivers' side door that has been messily superglued in place (the previous owner's handywork). Either that or the passenger side rear door that has a dent in it that looks suspiciously like another car's door has been banged into it in the supermarket car park, and rather than leave insurance details, the owner has buggered off
Not to derail the topic much further - I have access to a floor tile lifter (which is basically a suction cup device used to lift computer room raised floor tiles out). Should I attempt to use this carefully to pull out the little dings in my car, or is that just asking for trouble?
