This is the first out of just three vehicles which do not carry a Ferrari badge on this list. However, there is a connection with the famous company since 1939 was the year when Enzo Ferrari left Alfa Romeo. The 8C model was an amazing vehicle assembled just before the World War II started, and the car was elegant and powerful at the same time. Last August, this example was sold through RM Sotheby’s in Monterrey.
