Jonathan, many thanks for that extremely quick response pointing me in the right direction! Titanium7, following the links in Jonathan's guidance resulted in me having a chat with Tony at TSK and as you say, looks like my car is in "Mercedes bright silver 744". I now need to wait and hear back from the body shop to confirm or deny that that is the right colour. Failing that I will attempt to contact Caterham with the chassis number etc to see if they can help. Once again, many thanks. I appreciate you both taking the time to respond with your knowledge.
