A Bugatti Veyron used by Top Gear belonged to an Iranian immigrant and swindler who posed as a member of the Kuwaiti Royal Family. He also committed multiple frauds using his Kensington, UK car-hire firm.
Koroush Pour operated a company called Swift Hire near London for years, using the identities of customers to buy new and sell cars he owed hundreds of thousands of dollars on. Though born in Iran, Pour pretended to be an a member of Kuwait's royal family. Top Gear used his Veyron for one of their episodes. He was eventually busted for stealing $700K from a bank and $175,000 from two retired nurses.
Pour will be spending the next two years in jail where the fastest thing on wheels he'll likely pilot is a laundry cart. [UKPA via Google]
