Welcome to my all new DVD Thriller, which, as the name suggests, is all about thrills at the wheel. Aston Martin's gentleman thug, the DBS, takes on its rivals from Italy. The lightweight Lamborghini Superleggera battles it out on the track with Ferrari's 430 Scuderia and my test of the best takes me to the breathtaking roads of the Swiss Alps, the no limits German autobahn - and, er, Norfolk.
