Nick Mason used chunk of the money he earned from Dark Side of the Moon to fuel his other passion - exotic cars. The Pink Floyd Drummer bought a Ferrari GTO 250 and later offered the highly prized car as collateral to help his band secure funding to do its 1987 A Momentary Lapse of Reason Tour. The car, now valued at more than $55 million is an understandably special occasion auto. One came up when Mason got together with fellow gearhead Brian Johnson of AC/DC. Although he's an accomplished high horsepower driver himself, not even Brain could talk Nick into giving him a turn at the wheel.
