The one-off Lamborghini Aventador J is, without a shadow of doubt, the most astonishing car of the 82nd Geneva autoshow. It’s practically useless as a car, but as a poster – something to make small children go wow, it’s right on the money. It even has a special liquid red paint job which is just mesmerizing in the flesh.

Lamborghini has only made one Avantador J, and it’s already been sold to one of their special customers at a pretty fat price. But if you like yourself one of these, do not despair. In a few months time Lamborghini will unveil the Aventador Roadster, which will give you at least half of the thrill.

Here’s a nice ‘making of’ video Lambo released, showing the process of designing and building the J:
