Million Dollar Car Hunters

An Aston Martin DB4 Zagato sells for a whopping $13 million, and its owner spends even more money restoring it to mint condition ready for the world's most prestigious classic car show.

In London, the car hunters find a star car for the Monaco auction, a rare Ferrari 275 GTS/4 NART Spyder valued at over $19 million.

At the Detroit auction a beautiful 1929 Duesenberg goes under the hammer. It's easy to see why this car was often the choice of 1930s film stars such as Clark Gable and Ginger Rogers.

Gus test drives a rare 1951 Ferrari for the exclusive Monaco auction. While on America's west coast, David Swig inspects a stunningly rare 1955 Jaguar D-Type with an amazing history.

Weaver inspects the legendary Shelby Cobra CSX 2000. It could be the most expensive American car ever sold at auction. In New York, a rare pre-war Alfa Romeo is worth around $20 million.

In Scotland, Paul Darvill goes to see a barn find which is a rusting 1967 Iso Grifo sports car. It is estimated to be worth about £30,000, but could disintegrate before the hammer falls.
