A host of limited-edition Lamborghini Aventador models were produced during the car’s production run and while it’s hard to say which is the most special, many would agree that the one-off Aventador J is among them.

This special version of the Aventador was first unveiled at the Geneva Motor Show back in 2012, just one year after the original Aventador was presented, also in Geneva. The individual who commissioned it clearly wanted a car unlike any other and Lamborghini delivered, creating a Speedster well before modern supercar-based Speedsters like this became popular.

In the 11 years since the Aventador J’s premiere, it hasn’t been seen out and about all that often but the owner recently brought it to a Supercar Owners Circle event in Marbella, Spain. It looks just as good as it did the day it was unveiled and the owner reportedly declined a $10 million offer to sell it last year. Given that it cost a touch over $2 million to buy, it has clearly proven to be a good investment.

To create the Aventador J, the Italian car manufacturer removed the roof and made modifications to the carbon fiber monocoque. It also removed the windshield and the side windows, installed a new engine cover, designed small wind deflectors for the driver and passenger, and developed a set of unique 20-inch wheels for it. The Aventador J also rocks an eye-catching carbon fiber rear wing with swan-neck supports and has a rear-view mirror poking out from the dashboard.

Various other changes have been made to the car’s interior. For example, the red paint of the exterior continues down the center console and across the transmission. It also has forged carbon fiber bucket seats and racing harnesses.
