16. Bugatti Aerolithe
Bugatti was one of the most important sports and racing car brands in the 1930s. It was a position Bugatti deserved due to numerous victories and extremely advanced road cars. However, since Bugatti was a small company that relied on outsourcing bodies for their cars, they are hard to keep track of today. Most car histories are missing the documentation of their history. It’s estimated that Bugatti built and sold around 10,000 cars until 1947, and many of them were restored and preserved by drivers. However, there is one Bugatti that is possibly the most extreme classic car missing for 80 years. Unfrotunately, there isn’t any trace of its fate or whereabouts. This car is the legendary Bugatti Aerolithe.

Bugatti introduced it in 1935, building the Aerolithe on a T37 chassis with a design like the gorgeous Bugatti Atlantic. However, it came with a body they made from an extremely advanced aluminum-magnesium alloy called Electron. Since it wasn’t possible to weld Electron, the panels were riveted, which became a trademark detail. The car proved popular in car shows around Europe. It was also featured in magazine reviews, but then it vanished. Nobody knows where the car is and the people who made or sold it are long gone. Some people believe that it disappeared during the Second World War, but no one knows for sure. If the Aerolithe ever resurfaces, it could possibly be the most expensive car in the world.
