Hi Nick,
I suggest that your friends come along as normal members of the public (unless they have scoobs and want to join SES of course

)
As we will be going as a Subaru car club, i think its best we stick to only having Subaru's on display. If we start allowing extras we might end up with the stand looking a bit odd if people bring friends along in non-scoobs etc.
And besides, their entry fee all goes to a good cause
