     Comments    

Presented at the 1971 edition of the Turin Motor Show, like many other Zagato designs this car was born out of an understanding between friends. In the case of the Ferrari 3Z, the friend in question was Luigi Chinetti, the Ferrari representative in America who financed the decidedly angular spider with its almost square-cut nose and tail. It was penned by Giuseppe Mittino, Zagato's chief designer from 1970, and the principle feature of the design was the slotted mobile brow that, like the helmet of an ancient warrior, concealed the headlights. Of this 12-cylinder spider, which also featured a very modern front air intake design, the Gazzetta dello Sport wrote, "stylistically the car responds to the Zagato canon based on functional structures in a simple design free of stylistic excess". Imported to the United States by Luigi Chinetti, the one-off car was sold the very day it was presented and was, moreover, voted "Best Ferrari of America".
