Here's a link to what I imagine is the show, 12/13 Jan at the Birmingham NEC.
http://www.necgroup.co.uk/visitor/whatson/DisplayWhatsOn.asp?i=5930&p=1"The show, which marks the start of the new season for most fans, sees teams, drivers, manufacturers and championships host stands, make announcements and meet the fans at the prestigious event.
Visitors and motorsport enthusiasts will again be able to get up close to their favourite F1 car on the F1 Racing feature, and a number of new features to be announced in the next two weeks.
In addition, the Live Action Arena gives visitors the chance to get right next to the action as race-prepared cars rev-up and let loose in the custom-built showground.
Another big crowd-draw will be the first-ever Pistonheads Performance Car Show, which will run parallel to ASI. More than 25,000 sports car fans are expected to attend for features including a concept car gallery, supercar paddock, track day cars, performance tuned cars and car market.
The Pistonheads Show is an extension of the web magazine Pistonheads.com, which is one of the worlds biggest online communities in the automotive sector with 1.1million unique users." <<Wow that's some membership - I'd dispute that!!
