Sunning as it is, the BMW 507 was a spectacular commercial flop. After production costs skyrocketed, BMW had to pull the plug before the program dragged the entire company into bankruptcy. Only 252 were ever built.
But don't feel sorry for the lovely 507: The surviving cars will fetch $2 million to $3 million at auction today, while the car has lived on in spirit in the more than 75 years of BMW roadsters that followed it.
