The Big 5 is Aston Martin’s yearly series of 5 “experience” events. It includes three track days (at Silverstone, the Nürburgring and Spa-Francorchamps) and two driving-experience days (one at the Boxberg test center and one on-ice event in St. Moritz). This Monday (September 17) the fifth Big 5 event was held: the track day at Spa-Francorchamps. Over eighty Aston Martins came to this historic race-track in Belgium. 66 Aston owners taking their own car to the track, others renting a factory car for the day.
