The NART name stands for North American Racing Team, and the drop-top production run is credited to the U.S. Ferrari distributor Luigi Chinetti, who wanted to boost the 275 model's sales with a limited edition convertible model. Originally, Ferrari planned to build 25 cars, but despite the racing pedigree only ten found owners. The first NART Spider finished second in class at the 1967 12 Hours of Sebring, and the model also has some Steve McQueen cool about it due to a starring role in The Thomas Crown Affair.
This car, chassis #11057, was sold new in Madrid to a Spanish Foreign Legion colonel, and spent its first 14 years in Spain. In the early 1980s it was bought by a Swiss collector, who had it restored for the first time, and in the mid-90s it moved to the UK. The current paint scheme dates back to 2001, while the interior's beige leather re-trim is from 2009. Despite a gradual change in appearance, it is a fully numbers-matching car that still retains the 300-horsepower Colombo V12 it received at the Maranello factory.
A similar NART Spider was auctioned at RM Auctions' Monterey event in 2013, for a staggering $27.5 million. That specific example, finished in a brighter hue was estimated at 17 million tops, so it will be interesting to see whether this darker car will surpass its estimate at the auction held on May 14th.
