This is the Ferrari SP12 EC. The EC doesn't stand for extra credit, nor does it stand for easily containable. It stands for Eric Clapton. The legendary musician has been a long-time Ferrari owner, and to honor his dedication, the Italian company wanted to show its appreciation with a one-of-a-kind car customized completely to his tastes. 

The Ferrari Style Centre and engineers from Pininfarina and Maranello took his request to make a car that drew styling from the Ferrari 458 Italia and Clapton's favorite, the 512 BB. Clapton said it was “an incredible experience, one of the most satisfying things I’ve ever done."
