It was meant to be Fords only for 2010, and was loosely enforced for 2011 because the rule wasn't made clear until tickets had been on sale for a while. It's Fords only for 2012. There may be the odd non Ford out on track, but the vast majority will be Fords.

The driving license rules aren't ours, they're Silverstone's. It's up to them whether they'll let old style licences on track - if in doubt give them a call.

There 'may' be some available on the day - but get there early, as it sells out fast.

It was 102dB drive by last year IIRC so it will probably be the same. If in doubt bring a big silencer!
