Jeremy drives the new Land Rover Discovery to the top of Ben Tongue (all 1,700 feet of it), a Scottish mountain and gives us some handy survival tips such as: take some soup in a can and a can of lemonade. Richard travels to Switzerland to find the "maddest car" in the world - an amphibious vehicle with a hydrofoil made by Rinspeed. The Dodge Viper SRT-10 is driven by Jeremy and catches fire. A quality product. Joanna Lumley is the Star in a Reasonably Priced Car.
