The Holy Grail of Ferraris: The Ferrari 250GTO. 3-liter V-12 with 295 horsepower. Current value somewhere north of 50 million dollars.
Premiered in February 1962; 39 cars built 1962-1964.
I subscribed to Road & Track magazine for many years beginning in the early 1960s and remember seeing an advertisement in the back of the magazine for a used 250GTO for, if memory serves, $8,500. It might've needed work. Oh, for a time machine!
