Jeremy Clarkson, Richard Hammond and James May attempt to find the world's greatest four-seat supercar. Plus, Richard is on the test track in two very different muscle cars.

Jeremy Clarkson, Richard Hammond and James May test the Aston Martin Rapide, the Porsche Panamera Turbo and the Maserati Quattroporte as they attempt to find the world's greatest four-seat supercar.

After an early morning start in the City of London, the boys embark on a road trip across the south of England, stop off for a race around a closed-off business park, and end up undertaking a rather special chauffeuring job.

Meanwhile, Richard is on the test track in two very different muscle cars, the Chevrolet Camaro SS and Mercedes E63 AMG. And there's a double dose of celebrity as Harry Potter star Rupert Grint and F1 ace Rubens Barrichello take their turns as the Stars in a Reasonably Priced Car.
