Late last month, one of our favorite YouTube channels, Petrolicious, profiled an extremely rare 1967 Ferrari 275 GTB/4S NART Spider. It's had only one owner and is just one of 10 of its kind. And it just sold for $25 million at this year's Pebble Beach auction. Originally estimated to bring in somewhere between $14 million to $17 million, all proceeds will be going straight to charity. That original owner, Eddie Smith from North Carolina, was a businessman who became quite friendly with the US Ferrari importer at the time, Luigi Chinetti.

Because of this, Smith was given the rare opportunity to buy the NART Spider. Despite lucrative offers to buy the car, even from the likes of Steve McQueen, Smith refused to sell. He passed away in 2007, but his family recently decided to sell the car with no interest in keeping the profits for themselves. Now that's some real class. The Italian beauty is powered by a 3.3-liter V12 that's good for 300 horsepower and is paired to a five-speed manual. It also underwent a full restoration in 2009.
