It's not as good as previous years. If you've been in the last year or two, and you're not after something specific, then I'd say give it a miss.
But, despite that, we've ordered a set of two-way adjustable dampers, chosen which lap timer I want (I think), arranged a new aluminium radiator to be made, nearly sorted out our new tyres, perhaps sorted the onboard camera issues.
Maybe it'll be better on other days, but I was disappointed with the show compared to previous years.
