CNET Car Tech posted a set of photos of an extraordinary Ferrari collection. These cars are ultrarare, with examples such as the 342 America, just one of six built, and the F50 GT1, one of three built. The most expensive car in the collection is the 250 GTO. Although there were 39 of these cars built, they are valued at more than $10 million. These vintage and rare Ferraris were photographed at the Ferrari of Silicon Valley dealership in Redwood City.
