Lyndon Johnson – $91.6K, Amphicar

These photos show Lyndon Johnson in 1965 in a really cool car that was bought from personal finances. It’s an Amphicar—a cross between a boat and a car that worked both on land as well as in water. Made in West Germany, only 3,878 were built in the ’60s. And President Johnson was a practical joker, too. When visitors went to his ranch in Texas, he’d play pranks on them rushing downhill to his lake in the car shouting all the while that the brakes weren’t working. The Amphicar had front-wheel steering for water and land. This gave it less maneuverability than a regular boat.
