15: Lamborghini Sesto Elemento – Starting Price: $2.2 Million
Automakers have been experimenting with carbon fiber forever, but Lamborghini took it a step further with the Sesto Elemento. The weight of just 999 kilograms (2,202 lb) made the car as light as some compacts. But with scary performance thanks to a 570-horsepower V10 engine, this was fast.

There aren’t a lot of cars that can match the Lamborghini Sesto Elemento in terms of speed or design. This might be why this car was so expensive and rare at the same time.
