It's a whole lot of money for a used car. But it's no ordinary car.

An 1884 French-built steam runabout has sold for 4.6 million bucks at auction in Hershey, Pennsylvania.

It's billed as the world's oldest running family car. The auctioneers said the oldest of old cars has a top speed of 38 miles per hour and seats four. But going for spin takes more than just turning a key.

A drive around the block requires 45 minutes to build up steam in the boilers. The buyer hasn't been revealed by RM Auctions.
