All Lamborghinis are rare, but some buyers demand a car that's rarer than the rest. When Lambo figured out that these individuals were willing to pay big money for that exclusivity, it started building some truly breathtaking creations, including the Sesto Elemento.

Although the Sesto Elemento doesn't look like a car you could order from the factory, in fact 20 were made, and one of them is now for sale in virtually unused condition. All you need is 2 million pounds (about $3 million) to park it in your garage, according to Top Gear.

Originally intended as just a concept, the Sesto Elemento was built to show off Lamborghini's expertise with carbon fiber. That's where the car gets its name: Sesto Elemento means "Sixth Element" in Italian (referring to carbon, not a lost sequel to a certain Bruce Willis movie). Thanks to the extensive use of carbon fiber and an utter lack of creature comforts, the Sesto Elemento is unbelievably light for a modern supercar. At just over 2,200 pounds, it weighs slightly less than a 2016 Mazda MX-5 Miata.

It has quite a bit more power than a Miata, though. The mechanical bits are cribbed from the now-departed Gallardo, meaning a mid-mounted 5.2-liter V10 provides the motivation to all four wheels. With 570 horsepower and 398 pound-feet of torque, the Sesto Elemento will do 0 to 62 mph in an estimated 2.5 seconds.

This particular example is being sold by a private owner in essentially new condition. With just 12 miles on the clock, it's as untouched as a "used car" can be. The fact that the Sesto Elemento can't be driven on public roads might be one of the reasons behind the lack of mileage. Any driving done in this beast has to take place at a track. Hopefully the new owner will do just that, because squirreling away this superb supercar would be a crime.
