9. 1967 Ferrari 275 GTB 4 S N.A.R.T. Spider
Next on the list is yet another model from Ferrari, the 275 GTB 4 S N.A.R.T. Spider!
This version built by the Italian automaker was only available from a single American dealer, Luigi Chinetti.
The guy asked Sergio Scaglietti and Enzo Ferrari to build a few Spyder models which he bought for approximately $8,000 each, and your assumption is right, the models were convertible with no roof versions of the 275 GTB/4.
The production was supposed to be a custom run of 25 cars straight from Scaglietti, but just 10 were built, thus, making it one of the most valuable Ferraris.
The “N.A.R.T.” part of its name stands for Chinetti’s “North American Racing Team”.
