Look down the list of the most expensive cars ever sold at auction and you’re bound to notice one name coming up more often that just about any other: Ferrari. And not just any Ferrari, but the 250 series. Encompassing some of the most desirable classic road and race cars in the marque’s history, the 250 series included such stand-out – and highly sought-after – examples as the GTO, the Testa Rossa and the California Spider. This past weekend at Pebble Beach, one such California joined the ranks at an astonishing $11 million.
