This 1964 Amphicar 770 was purchased new by Duane Hagadone, founder of the Coeur d’Alene Resort in Idaho, and acquired from him by the seller’s father in 1984. The seller’s father replaced the top and tires, repainted the car Regatta Red, and added it to his car collection. It was stored in Lewiston Idaho for two decades before the seller acquired the car in 2007. He had the brake system overhauled, added an automatic bilge pump, and replaced the mounts for its original 1,147cc Triumph inline-four, which is paired with its original four-speed manual transmission. This Amphicar is now offered with its tool roll, jack, owner’s manual and a clean Washington title in the seller’s name.

Manufactured in Germany, the Amphicar was designed by Hans Trippel, who was also responsible for the Mercedes-Benz Gullwing’s doors. This example was originally Sand White, although the seller’s father had the car repainted in Regatta Red in the 1980s. The seller notes that the tires date to his father’s ownership and are approximately 35 years old. The seller reports that the Amphicar is used on nearby Lake Ki every summer.

The top reportedly has not been used in some time, and the seller notes damage around the securing rivets and an inoperable side zipper. The seller typically uses the top well to store life jackets and a fire extinguisher when the vehicle is in use.

The cabin is trimmed red and white vinyl upholstery, which the seller reports to be original, with a new floorboard and mat. The car is also equipped with its factory two-spoke steering wheel and manual windows. The seller states that neither the clock nor the radio are functional. Only 6,250 miles are shown on the mechanical odometer, approximately 400 of which were added on the seller’s trips to nearby freshwater lakes.

The Triumph-sourced 1,147cc inline-four is mounted at the rear of the vehicle. The seller’s father converted the car to electronic ignition, and the seller has installed a rebuilt starter, an oil-pressure switch, a new fuel line, and a new battery. The brake system was rebuilt by Crossroads Texaco in Bellevue, Washington. The most recent service included an oil and filter change in May 2019.

Power is transmitted to either the rear wheels or the reversible dual propellers using a four-speed manual transmission with a separate selector for the prop drives. The props and the wheels can be run concurrently when driving the vehicle in and out of the water. Some corrosion is noted, and per the seller sealant was applied to both the battery tray and the rear quarter panels in 1985.
