Jeremy Clarkson celebrates the return of the handcrafted, coach-built car with a trip to Italy to drive the achingly beautiful and incredibly rare Alfa Romeo-based Touring Disco Volante. Richard Hammond attacksthe dunes of Abu Dhabi in a remarkable six-wheeled Mercedes called the G63 6x6, while James May makes a rare trip to the test track to try out the intriguingly minimalist Caterham 160 and its insanely fast sister, the 620R. Also in the show, comedian Jack Whitehall tries his hand as the star in the Reasonably Priced Car.
