Clarkson, Hammond and James take on the challenge of making an ordinary second-hand car lap the test track as fast as a brand-new, purpose-built sports saloon. James enlists the help of F1 world champion Mika Hakkinen in a quest to discover why the Finns are such good racing drivers. Richard hammers around the track in the outlandish Veritas sports car. Mark Wahlberg is the Hollywood Star in a Reasonably Priced Car.

Arriving in Vietnam, Jeremy, Richard and James have to travel the entire length of the country in just eight days. But first they have to buy some suitable transport for the trip, and despite having several million Dong in their pockets, this proves to be rather more difficult than they expected, especially in one of the most expensive car markets in the world.
