Bugatti Veyron Pur Sang
This car is so exclusive that only five of them were ever sold, all of which within 24 hours of the unveiling at a price of £2.3 illion. Built with almost no sharp edges, the two-seater Pur Sang was meant for luxury and also speed. Its 8L 1001 horsepower 16-cylinder engine lets the car go from 0 to 62 mph in just 2.5 seconds.
