Why it matters

The N.A.R.T. Spider was an open version of the 275 GTB/4 built by Scaglietti at the request of Luigi Chinetti, Ferrari's North American importer, for American buyers. Only 10 were made; Road & Track called it the most satisfying sports car in the world, and one appeared in the film The Thomas Crown Affair.

History

Chinetti persuaded Enzo Ferrari to build a small run of spiders on the four-cam 275 GTB/4 chassis for the US market and named them after his North American Racing Team. The cars kept the berlinetta's 3,286 cc four-overhead-camshaft V12 with six Weber carburettors, five-speed gearbox, all-independent wishbone suspension and four-wheel disc brakes on a tubular steel frame. RM's catalogued car, chassis 10709, had been raced at Sebring by Denise McCluggage and Pinkie Rollo.

Identification guide

How to tell an original from a replica or later conversion.

Genuine cars are open two-seat spiders on the 275 GTB/4 chassis carrying a North American Racing Team badge on the tail. Originals are numbers-matching, with engine number equal to chassis number (for example 10709).
