Only ten Ferrari 275s officially came from the Ferrari factory in spyder configuration. These were all made for Luigi Chinetti who was Ferrari’s North American Importer at the time.
Chinetti recognized the need for an alternative to the luxurious 330 GTS and reluctantly convinced Ferrari to deliver his own ‘NART Spyder’.
Chinetti first got the idea for the car at the Paris Motor Show when the 275 GTB/4 was shown. Ferrari at first denied his request to built a factory spider, but after talking to Sergio Scaglietti who manufactured the 275 bodies, Ferrari was finally convinced. Chinetti named the car after his North American Racing Team (NART) which contested all the top races in US and abroad.
Initially, Chinetti ordered 25 cars which were executed by the experienced craftsman at Sergio Scaglietti’s workshops. Although the chassis of the 275 relied on the body for rigidity no additional bracing was introduced with the NART Spyder.
In the end, Ferrari only shipped 10 Spyders to Chinetti and they were all sold through his eastern USA dealership. The first of these cars came with aluminum body and was immediately put into race duty to promote the model. After the race, Chinetti had a hard time selling the cars and had to sell the final few at a marked discount.
