6. DKW, Not DSW
Vehicle: 1937 DKW SB500
Complex Says: When you own a vintage vehicle, you tend to pay more attention to interesting facts about that vehicle. The seller of this WWII-era German motorcycle mentions knowing fewer than five other examples of this model in the U.S. The seller also states that the bike is almost completely original--and still runs well. One unique feature we should mention is that this bike has an electric starter that was installed at the factory. Yes, in 1937. It took other bike manufacturers how long to catch up? Classic German car enthusiasts might be more familiar with the DKW company for their automobiles--and the fact that it was one of the companies that was later folded into Auto Union, which later became Audi.
