"NART" was never part of this model's official designation from the factory, a cloisonné badge with the team's logo was installed on the rear of each car. Chinetti intended to order 25 NART Spiders from Scaglietti, but because of low sales just 10 were built in 1967 and 1968, making this one of the rarest 275 models. The ten NART Spiders used chassis numbers 09437, 09751, 10139, 10219, 10249, 10453, 10691, 10709, 10749, and 11057. The magazine Road & Track published a road test of a then-new NART Spider in its September 1967 issue, describing it as "the most satisfying sports car in the world." This test recorded a 0- time of 6.7 seconds, a drag strip time of 14.7 seconds. and a top speed of . The first produced 275 GTB/4S (chassis 09437) was entered in the 1967 12 Hours of Sebring, driven by Denise McCluggage and Marianne Rollo. They finished 17th overall, and 2nd in the 5-litre GT class. Following this race, the car was repainted from its original "Giallo solare" yellow to a burgundy colour for an appearance in the 1968 film The Thomas Crown Affair, where it was driven by Faye Dunaway's character. The same car was subsequently tested by Road & Track for their September 1967 road test article. In August 2005, 09437 sold for $3.96 million at Gooding & Co.'s Pebble Beach auction. In August 2013, a 1967 275 GTB/4S NART spider (chassis 10709) sold for (US$27.5m after commissions) at RM Sotheby's Monterey, California auction. At the time of the auction, this was a one-owner car, previously owned by Eddie Smith of Lexington, North Carolina. Mr. Smith purchased it new in 1968 and drove it regularly until his death in 2007. Subsequently, the car remained in possession of his family until the 2013 auction sale. Mr. Smith Jr. felt that the car was "sort of being imprisoned" hence the reason for the selling it. The winning bid was by Lawrence Stroll, collector and part-owner of Aston Martin Formula One team. The Smith family announced that the proceeds of the sale will be donated to charity.
