Just an FYI: I just came back from taking the factory tour in Sindelfingen, near Stuttgart. Part of the tour was going through the huge metal stamping plants for the sheet metal. The tour operator said that when the dies have stamped their life quota, then they sell the dies to aftermarket companies, so you may be getting sheet metal from actual Mercedes dies, it may just not as perfect as the original. By the way, the tour was great, (the Porsche tour was even better).....doug
