8. Ferrari Pininfarina Sergio – $3 million
This model appeared as a concept car five years ago, but it entered production with Ferrari launching only six models thus far. They are all handmade and use frame entirely made out of carbon fiber. This luxury supercar has room for two, and just like the Ferrari 458 which served as an inspiration, the Pininfarina Sergio has no roof, windshield nor side windows. The engine that powers this beast is a naturally-aspirated 4.5-liter F136F V8 good for 562 hp.
