This Ferrari was made just for America, and it's the last of its type - now it's worth $26 million

Sometime in the mid-sixties, the main Ferrari importer in America, a racing driver named Luigi Chinetti, decided that there was a gap in the Ferrari lineup.

He asked Enzo Ferrari himself for a convertible version of the 275 GTB/4, in which his American customers could soak up a little sunshine.

The result was the beautiful 275 GTB/4 NART Spyder - named for the North American Racing Team, Ferrari's stateside endurance racing program founded by Chinetti himself.

The car made a Hollywood appearance in the original 1968 version of "The Thomas Crowne Affair," in which it was ogled by the titular character, a millionaire playboy and art-thievery enthusiast played by Steve McQueen.

The actor and noted car devotee would later buy a NART Spyder for himself.

Only ten NART Spyders were ever made, and all were intended to make it to the United States.

Except - oddly enough - this one, which was sold to to a Spanish Colonel of the Foreign Legion in February of 1968.

At an RM Sotheby's auction in Monaco this weekend, this NART Spyder will headline an already star-studded docket, and is expected by the house to sell for between €19 million and €23 million ($21 million and $26 million).
