Back in 2010 at the Paris Motor Show, Lamborghini revealed something even more wildly bonkers than usual. It was called the Sesto Elemento, or "Sixth Element" in English, and it immediately became a smash hit. Weighing in at only 2,200 lbs, the Sesto Elemento was a mad scientist experiment of sorts in carbon fiber technology. The body, chassis, drive shaft, and suspension were all made of the lightweight material. Power came from the Gallardo's 5.2-liter V10 totaling 570 horsepower and 400 lb-ft of torque.

Power was sent to all four wheels via six-speed auto with paddle shifters. Air conditioning and a stereo weren't included to keep weight down. Just 20 were made and none of them were street legal; there's just something awesome about track-only supercars. Obviously all sold out in a near instant, with prices ranging from $2.2 million to $2.9 million. But now one Sesto Elemento has gone on the market for an asking price of $3 million. We're not sure who the seller is as the listing was posted privately on the 6speedonline forum. Only serious inquiries are being considered and the car is available for immediate delivery. In fact, it's the only Lamborghini Sesto Elemento for sale in the world at the moment.
