For his final drive, Richard returns to the country of his birth in a splendid 1950s Bentley. He drops in on his sister, returns to the original 'Dr Finlay' house, takes to the water to find out how Sir Walter Scott inspired a deluge of sightseers to the region, drives Scotland's most famous road in the company of a bevy of vintage bikers, and discovers just what it is about great vistas that gives us all such a thrill.
