Jeremy Clarkson joins a gathering of Ford RS enthusiasts before taking the new Focus RS to a suitably deserted stretch of road. He also tests a remarkably quick supercar built in a shed in Leicestershire — the Noble M12 GTO. Meanwhile, Richard Hammond fulfils a childhood ambition by driving a Ford Escort RS1800 and discovers how many motorcycles a double-decker bus can jump before things become expensive. Jay Kay is the Star in a Reasonably Priced Car.
