Built in an ultra-limited run of just 10 cars, the 1967 Ferrari 275 GTS/4 NART Spyder is the open-top counterpart to the famed 275 GTB/4, created at the urging of Ferrari’s U.S. importer Luigi Chinetti for the North American Racing Team (NART). Under its elegant Scaglietti-bodied lines sits Ferrari’s 3.3-liter quad-cam Colombo V12, breathing through six carburetors and paired with a rear transaxle for poised, balanced performance. With competition pedigree, breathtaking proportions, and rarity that borders on myth, the NART Spyder remains one of the most desirable—and valuable—Ferraris of the era.
