Michael Madsen is looking to turn the yellow Cadillac he drove in Reservoir Dogs into a personal windfall after agreeing to auction off the classic car online. The tough guy actor was given the classic 1964 car as a gift from Reservoir Dogs director Quentin Tarantino - and now he's looking to sell it after realising how much it could be worth. He tells Maxim magazine, "I'm going to put it on eBay. They got 70 grand for the Brokeback Mountain truck, so I figure it should be worth a few pennies."
