Never seen before at a motor show anywhere in the world, Aston Martin has selected Salon Privé London to reveal the Aston Martin V12 Vantage Roadster to visitors to the Supercar Show and Concours d'Elégance at Syon Park, West London this week. Priced at £150,000, the 6.0 litre V12 convertible will reach 62mph in just 4.5 seconds, and will keep going all the way up to 190mph.
