The Amphicar was the first amphibious automobile mass-produced for sale to the public. First sold in 1961, the German vehicle was designed by Hanns Trippel and manufactured by the Quandt Group at Lübeck and at Berlin-Borsigwalde. The Amphicar was primarily designed to be marketed and sold in the United States, but many of the early adopters were in Britain and Germany. Several were purchased by the West Berlin police to patrol along and in the Spree River. Although only about 4000 were sold before the company folded four years later, the Amphicar is still the most successful amphibious civilian automobile of all time.
