Lamborghini said that the J is a one-off and has already been sold to a lucky customer for £1.75million ($2.8M)

Fans of super cars, if you thought that the Lamborghini Aventador was already a pretty awesome car, then you might want to take a look at this super rare Lamborghini Aventator J, which is pretty much the Aventador that seems to have done away with some of its body parts, namely the roof and the windshield, which the company has decided to replace with wind deflectors that are aimed to keep the wind from blasting directly at your face as you race down the highway.

2012 Lamborghini Aventador J Concept roadster super sports car debut at the 2012 Geneva Motor Show. The letter J is derived from the sporting rules of the FIA world motorsport organization. Its “Appendix J” defines the technical specification of race cars in the various classes. The unique expertise of Automobili Lamborghini in the field of carbon fiber reinforced polymers is evident not only in the hi-tech monocoque, but also in the research into further innovative solutions. Unlike traditional seats, in the 2012 Lamborghini Aventador J Concept seats are made of Forged COMPOSITE®, with inserts of flexible carbon fiber fabrics: a result of an innovative Lamborghini patent.
