Thanks for all that info. I'll keep looking. I didn't buy them but they were on the car when I bought it. The previous owner says that they were bought from someone in Prague. The only parts company I contacted to try to source them was in Britain and they were mystified; guess they were never an option on British cars. I believe that BWA Alloys were made in Milan, do you know if I'm correct on this? If these centres are worth that kind of money and are sought after they look like a good candidate for someone to re-manufacture.
