Chris Harris reviews the Aston-Martin GT12

Chris Harris reviews the Aston-Martin GT12: A racer-inspired supercar made in Britain. Starting with a Vantage V12 S, they significantly widened the car's wheelbase and bodywork. Then they lightened the car and tuned the engine to deliver 600 horsepower to the rear wheels. New suspension and some new rubber finishes the job. I'll have mine in black please.
