Not sure if this has been mentioned before, did a search but couldn't find anything. It's a good day out, I've been with my son the last 2 years. It's a charity event organised by Petrolhead Nirvana and a couple of other forums, held at the TopGear test track (Dunsfold). Basically a load of drivers of some pretty exotic metal blast passengers around the track for money, all the proceeds going to The Childrens Trust. There are always some nice motors - Ferrari F40's, Enzo, sometimes an F50, Zonda, Lexus LFA, a whole host of other Ferraris, Lambos, Atoms, X-Bows etc. etc. It's a good day out, more details at the link: http://www.thesupercarevent.com/index.php/2013-event - Maybe a chance for a SE meet? (there's a huge parking area).
My ride last year:

My son George in the Enzo:

My brother normally brings this (previous owner Mr J Clarkson
)

Peter Saywell normally brings some of his collection:

My Son George in the Enzo, 2011 (he couldn't hold the camera very still bless him)
