They even made one or two 600 coupes, only for high level MB management.

The Germans are buying these old cars like a Barret-Jackson auction sells a hemi Chrysler product. That car has more value in Germany than the U.S., mostly because of what it stood for at the time. For many years after the war, many Germans could barely afford a small BMW 1600 or VW product, any MB was the stuff of dreams. You had to get on a waiting list to buy one, and much to the chagrin of German citizens, U.S. Armed Forces stationed in Germany got preferential treatment. With no wait list.

For many western Europeans that grew up in Europe after the war, a 600 is like one of the GM Motorama cars from the '50s.
