This is a three-of-a-kind and completely road-legal showpiece based on the Aventador. It has the same 6.5-litre V12, boosted to 739bhp with a 220mph max. It has the same permanent 4WD, inboard pushrod suspension and carbon monocoque chassis. It costs $3.9 million and the trio of owners has already been found. It has been built to celebrate Lambo's 50th birthday.
