Only one of these cars exists on the planet, but as one of the company's most impressive creations, the Aventador J still needed a proper promo video. Built in just six weeks, the J, also known at the Unica, was specially built at the request of some really rich dude. 

"The new Lamborghini Aventador J is the most radical open supersports car of Lamborghini’s history," said President and CEO of Lamborghini Stephan Winkelmann. "Its name comes from our tradition and combines an unconventional design with technology innovation. Nowadays we are confronted with several regulations that we face in the spirit of challenge. The Aventador J is the proof that, despite the rules, Lamborghini will always make people dream, even in the future.“

Expect much of the beautiful design to be carried over into the Aventador Speedster coming soon.
