World's oldest car auctioned off

(CNN) - The world's oldest-known running car has a new owner.

Someone paid $4.6 million for a steam-powered car at an auction in Pennsylvania on Friday. That's double the amount auctioneers expected.

The four-wheeled car, nicknamed "La Marquise," was built originally built for the French Count De Dion in 1884. It's fueled by coal, wood and bits of paper.

The car takes about a half-hour to work up enough steam to drive. It can go up to 38 miles per hour.

The new owner's name hasn't been released.
