I think I saw this car at the Concorso Italiano last year. I was talking with a guy that had a twin turbo Diablo and he was saying how he got it in an auction when it was seized from an off-shore gambling guy that got nailed by the government. The new owner said that he was bidding against Nicolas Cage for the car. It was like 1 of 7 that were factory turbo Diablos:
