Aston Martin 's story is one of engineering triumph in the face of financial adversity. In a special profile of the company, Jeremy Clarkson has the chance to drive some of its finest cars, including the post-war Atom, a DB4GT, the DB5 used in the film Goldeneye, a DB6 Volante and the latest V12 DB7. He tells the story of the company's decade-long struggle to win Le Mans, and talks to Stirling Moss about what the old racing Astons were like to drive.
