You could be forgiven if you've lost track of the train of Ferraris that have claimed the title of "world's most expensive car" over the past few years. It's a surprisingly long list. But recently, a new record was set, and it's a whopper: A 1962 Ferrari 250 GTO, painted in a rather unsettling pastel green, sold for $35 million.

So what makes this particular 1962 250 GTO so special, apart from its unique place in history and incredibly limited volume? It was built for racing legend Stirling Moss. The unique green color was part of the livery for Moss's UDT-Laystall racing team. Unfortunately, Moss's career was ended by a racing injury before he could take the wheel of the green GTO.

The sale was a private transaction, so it doesn't set a new bar for the highest auction price--that honor still likely belongs to a 1957 Ferrari 250 Testa Rossa sold at Pebble Beach in 2011 for a still mind-boggling $16.4 million.

Before the latest private-sale price hike, the record holder was, yep, another 1962 Ferrari 250 GTO, which traded hands for a cool £15.7 million ($28.7 million) in the U.K. in 2008.

As for the $35 million GTO, one of just 39 built from 1962-1964, it was sold to Craig McCaw, an American classic car collector, according to BusinessWeek. The previous owner was Eric Heerema, a Dutch-born businessman living in England.
