My wheel trims will need replacing soon. The ones I got were £4.99+VAT (for four), but they don't seem to be as robust as the original FIAT ones. They seem to have been worn over time from grit, and don't look so good now. My original FIAT ones were badly scuffed from the previous owner, but didn't appear to be erroded from grit. Has anybody else found that the FIAT ones are more robust. Do you think it's worth paying £31 for a set of FIAT ones?
