The Veneno is a limited production supercar, which is based on the Lamborghini Aventador . The Veneno was built to celebrate the 50th anniversary of Lamborghini. The car was introduced in 2013 and came with a price tag of $4,500,000 which made it to the most expensive production car in the world. The prototype of the Veneno is grey and has the Italian flag on both sides of the car. Lamborghini only built 5 units of the Veneno which makes this car even more wantable. One unit was used for factory testing, one, Lamborghini kept for themselves and three units went to costumers. The prototype, Car Zero, will be retained by the factory for the museum. The top speed of the car is around 350 km/h and it can accelerate in 2.8 seconds from 0-100 km/h.
