AT THE Frankfurt Motor Show next month, Aston Martin will announce the price for its new DBS, a car that combines the luxurious comfort of the DB9 and the edgy sportiness of the DBR9 track car. Powered by a 6-litre V12 with 510 horsepower on tap, the two-seater is expected to clock a 4.3-second century sprint and a top speed of 302kmh - making it the fastest road-going Aston available.
