I bought my car used and a few things I have discovered are not as originally advertised. The write-up said the car came with option 423 20" Carrera S wheels. But when I look on ebay it seems like these are the 20" Cayman S wheels which weren't an option but of course some could always swap. My only interest is that I would like to buy a single extra wheel for the eventual flat (bearing in mind that I would put a front tire on it for short drives). From what I can tell online, the Carrera's are polished alloys and the Caymans are painted and mine appear to be painted making them the Cayman's. Without taking the wheel off, is there a way to tell? Thanks.
