1961 Amphicar
One of the world's only amphibious cars, the Amphicar was the creation of German engineer Hans Trippel, who had long had a thing for amphibious cars, having designed the 1934 SG6, and later the 1939 Schwimmwagen, for Adolf Hitler.
After World War II, Trippel looked to develop his amphibious cars into something appropriate for the consumer market. For his new car's engine, he chose one from the Triumph Herald, a lightweight, tough 39 hp (29 kW) 1.1 L engine. Debuting as the 1961 Amphicar 770 and selling for 10,000 Deutsche Marks, or $2,479, it wasn't exactly a hit. After all, how many people needed a car that could do double duty as a boat?
