A former military air base, the Dunsfold Park Airfield is best known as the home track of hit BBC show "Top Gear
". But what is the circuit used for when Clarkson and company are off on their worldwide tours? For hosting supercar gatherings and charity events, of course. FgearTV was recently at the British track and filmed a terrific 90-second video of the 2012 Supercar Event. Though there was a considerable amount of rain during the weekend event, there were still plenty of incredible cars on show.
