One Ferrari at least is gone according to Wikipedia
"On 18 May 2008, Evans attended RM Auctions/Sotheby's Ferrari auction in Maranello, Italy, and bought a 1961 250 GT Spyder California SWB formerly owned by US actor James Coburn for the then world record price of 6.4 Million Euros. In May 2010 he bought a 1963 Ferrari 250 GTO, one of only thirty-six built, for ?12 million. Reportedly he sold three Ferraris from his collection to pay for it. He sold it three years later for $42 million, more than double what he paid for it."
