What you're looking at is a one-off Ferrari that attempted to do something truly great: break the world speed record at the Bonneville Salt Flats. And, believe it or not, it's based on the iconic Ferrari Testarossa. But it wasn't built by Ferrari. Designed by German industrial engineer, Luigi Colani in 1989, the Ferrari Testa d'Oro was built to break the speed record set by the Mercedes Streamliner in 1939. This one-off was assembled by German tuning firm Lotec, and had a pretty awesome engine.

A Ferrari-Lotec 5.0-liter twin-turbo flat-12 with 750 horsepower at 4,000 rpm and 660 lb-ft of torque at 5,000 rpm. It made its first speed attempt in 1989 and hit 211 mph. That wasn't good enough to set a new record, likely due to insufficient tires, so another attempt was made in 1992. With a 218 mph top speed, it still didn't break the Mercedes' record, but it did earn the distinction of the fastest car with a catalytic converter. And now this one-off is for sale. How much? No clue, likely because of its exclusivity. Translation: the price will only be given to serious inquires.
