Amphicar 770
The Amphicar 770 remains the most successful amphibious automobile ever produced, with 3,878 units built between 1961 and 1968. Designed by Hans Trippel, it utilized a Triumph Herald engine mounted in the rear, driving both the wheels on land and twin propellers in water. The designation 770 referred to its maximum speeds: 7 mph on water and 70 mph on land. While not exceptional in either element, the Amphicar delivered genuine amphibious capability in a practical package.
Most Amphicars were sold in the US and many survive there. Verify the hull integrity and check for corrosion in the bilge area. Water seals are critical and require specialized maintenance. The Triumph engine is robust but parts are increasingly scarce. Budget $10,000-20,000 for a comprehensive restoration. Values range from $45,000-125,000 depending on condition.
Production took place in Berlin from 1961-1968. Most examples were exported to the United States. The car used a Triumph Herald 1200 engine and many British components. Increasing safety regulations and high production costs led to the company's closure.
