email from Den Tanner that clears things up so see you all there
If you turn up in a tin-top the charge is £25 to camp. For that price you'll also receive two show entry tickets to get into the actual exhibition.
If you turn up in a kit car, you'll be GIVEN two free tickets (one for each day) and you'll be charged just £5 for your camping plot.
For obvious reasons, I'm trying to discourage people attending (as campers) in 'ordinary' cars.
Does that make sense?
