On this episode of Head 2 Head, Carlos Lago pits two great Britons against each other: the Aston Martin V12 Vantage S and the Jaguar XKR-S GT. The similarities between these two run deep.

The factories responsible are 37 miles from one another; it's easy to imagine the engineering groups meet for warm beer -- or tea. Which one deserves the bragging rights?
