If you are a billionaire and want to have a one-off supercar we recommend the Lamborghini Pregunta Concept, a car that was unveiled back in 1998 at the Paris Motor Show. Built on a Diablo chassis, the Pregunta is a supercar with a carbon fiber bodywork and features a V12 engine delivering 530 hp and a top speed of 207 mph or 333 km/h.
Pregunta (Spanish for question) was designed by French firm Carrosserie Heuliez, before Lamborghini was officially sold to Audi by Tommy Suharto, son of the former Indonesian president. Apparently, the Lamborghini Pregunta was inspired by the aerospace industry but also by the Formula 1. Despite the fact that it was 1998 when it was built, The Lamborghini Pregunta featured optical fiber lightning and cameras instead of mirrors.
So, if you really want the Pregunta you will have to pay $2.1 million. The concept car could be a solution for those who wanted to buy the limited Lamborghini Veneno recently unveiled at the 2013 Geneva Motor Show.
