The first half of a two-part special, the filming of which caused controversy in Argentina because of a registration plate that drew links to the Falklands War. Jeremy Clarkson, Richard Hammond and James May take three used V8-engined sports cars on a gruelling road trip covering 1,600 miles through Patagonia.
