We've had our 500 just over a month and 1000 miles now and the paint has started to come off the wheel centre caps (the car is never washed with a power washer, only a gilmour foaming attachment with non caustic foam, and the wheels were waxed from new) seems that the centre is chrome plated and then the dark grey centre is simply painted over the top. Thing is the service fella at Mirafiori Autovillage has already seen at least 5 examples personally since November.
