Top Gear: South America Special by Nigel Simpkiss

8.74

Jeremy Clarkson, Richard Hammond and James May are dropped deep in the Bolivian rainforest armed only with three 4x4s which they bought from the local small ads for a maximum of £3,500 each. They attempt to drive from the heart of Bolivia to the coast of Chile, encountering drug lords and the debilitating effects of high altitude. Without a doubt one of the toughest challenges the `Top Gear' team has ever faced.
