Comedian and longtime "The Tonight Show" host Jay Leno took the mantle from none other than Johnny Carson, and his success earned him one of the world's most celebrated car collections. Roughly 150 vehicles strong, the funnyman's fleet is worth an estimated $50 million. It contains gems like a 1912 Stanley Steamer Vanderbilt Cup Racer, a steam-powered antique that earned Leno a speeding ticket in 2010 when he was busted cranking it all the way up to 75 mph, according to Autoblog. The crown jewel in his collection, however, is a 1994 McLaren F1, which he bought for $800,000 but which is now worth an estimated $12 million. According to CNN, it's the first car Leno would save in case of a fire.
