Have you priced bumpers? I don't know what condition the rest of your car is in, but how deep are your pockets? If you need a lot of OEM parts for a Concours restoration, then be ready to help with Germany's balance of trade. But if you want a pretty car for frequent driving, then the re-pro's should be fine. I'm planning to go the re-chrome route for some of the smaller trim pieces on mine, but I don't need bumpers.
Good luck and welcom to the group!
