The Lamborghini is a mid-engined sports car that debuted at the 2007 Frankfurt Auto Show. It is currently the most powerful and expensive Lamborghini road car to date, costing one million euros. The official press release states that only 20 examples will be released to the public, with a single car (0/20) produced for the Lamborghini Museum. Although early rumours indicated the total number would actually be 100, each Reventón is clearly stamped with its number in the sequence of 20 between the drivers and passengers seats.
