BMW enter the small hatchback market with the launch of their 1 series - James drives it and wonders why they bothered. James and Jeremy test cars from Asia and hate them all and Jeremy drives the Ariel Atom. The Mercedes G Wagen gets the AMG treatment and Richard gets to drive it.

Another epic race pits the car against public transport. Richard and James travel by aeroplane and train in an attempt to beat Jeremy - driving a Ferrari 612 Scaglietti, to their destination at Verbier in Switzerland.

Richard takes the new Mustang on a road trip along Britain's straightest road in Lincoln. The Prius, a supposedly eco-friendly vehicle is driven by Jeremy, who thinks that a diesel Lupo will actually do more miles per gallon - 75 compared to the 45mpg of the Prius.

Richard, James and Jeremy are set a challenge; buy a working Porsche for a maximum of £1,500. Richard bought a 924 (the one with the van engine) for £750, James a 944 for £900 and Jeremy - predictably a 928S for £1,500. They were then set a series of challenges to see who had bought the best car.

The Morgan Aero 8GTN is driven by Richard and derided by James and Jeremy. James and Richard pay tribute to the London Routemaster bus; Richard tries his luck at Historic People Carrier Racing and Jeremy takes a Jaguar S Type diesel to the Nürburgring in Germany, to see if he can complete a lap of the 13 mile circuit (with 147 corners) in under ten minutes.

Richard drives the new 218mph, £400,000 Pagani Zonda Roadster in Switzerland - one of only 40 that will be built. He compares it to the Wally 118 - a £14 million pound boat made of lightweight material such as carbon fibre.

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. It's clearly not a quality product.

richard drives the new Ford Focus and compares it to its rivals. Pink Floyd's drummer, Nick Mason, lends Jeremy his new Ferrari F60 Enzo in return for a subtle plug for his new book. There's a race between a grumpy teen on an all terrain board and a Mitsubishi Evo7 Group N rally car - and a Bowler Wildcat just for good measure. Ben Collins drives the cars.

Cars from the "colonies": the Vauxhall Monaro VXR from Australia and the Chrysler 300C from the United States take on the Jaguar S Type R on the beach at Pendine Sands in south Wales. Back at the Top Gear track, Jeremy is trying to tell the difference between the old Porsche 911 Carrera and the new Porsche 911 Carrera S.
