Built to order for the wealthiest and most demanding enthusiasts, the Mercedes-Benz 540 K Special Roadster was the flagship of the brand in the prewar years. Introduced in 1936, just 26 540 K Special Roadsters were constructed before the Second World War brought new car construction to a halt, and of these, only a few were originally exported to the United States.Â
