Thanks to everyone for the great advice. I'll be going on the MB Master Guild trip as a guest of MBUSA/DaimlerChrysler. The itinerary includes visits to the Sindelfingen production plant, the AMG plant at Affalterbach, the DC museum and test track at Unterturkheim, and the engine production facility at Cannstatt. At Kirchheim we'll tour the fuel cell development center. We'll also be taking a day trip to Switzerland for some sight-seeing, which I'm pretty excited about. There's also a few boat rides, castle tours, and some free time to do whatever I want. I'd like to get one of those Black Forest Cuckoo Clocks that I hear Germany is renowned for. Does anyone know of any clock shops in Heidelberg or Stuttgart?
