The Mercedes 300 SL Gullwing has an interesting history, as it was originally nothing more than another race car in the early 1950s. An American importer by the name of Max Hoffman pressured Mercedes to turn the car into a road-going coupe for the masses, and eventually – in 1954 – Mercedes did just that. 1,400 units were built between 1954 and 1957, with a large majority going straight to the U.S. market. Since then, the car has become desirable and collectible, with examples going for more than $1 million in some cases. A recent sale of an example from 1954 was just sold by RK Motors Charlotte for a total of $1.9 million, marking a three-year high for the 1954 model.
