The challenge this week is to buy a coupe that is not a Porsche for no more than £1,500. Richard buys a BMW 635i, Jeremy a Mitsubishi Starion and James bought a "grandfather clock". Or the Jaguar XJS as it was better-known. Jeremy drives the new supercar from Maserati, the MC12 and Jack Dee is the Star in a Reasonably Priced Car.
