In the early 1950s, an American serviceman bought a strange car at a Swiss used car dealership on the advice of a friend back home. The car turned out to be a Ferrari 166MM, one of just 25 cars built and the model that helped establish the brand as a performance car powerhouse.

The car was run in Arizona for a few years until something broke. So it was left in a backyard for over four decades until the owner died, and his children put the word out about the car. It was sold to a California collector in 2007 for over $1 million.
