It's hard to say as I know a lot of people that have said they are definately going to go but haven't paid up yet!
I know I have a fair few coming along from SXOC, obviously you lot from here, a few from IMOC (MR2's), I also posted on **REMOVED**, a few from Skyline Owners.
Matesoff the forum have all posted on their own clubs as well, I have just covered a few of the Nissan ones
Last run we had over 100 cars, most people sign up right at the last minute, so I think the list wil grow quite a lot the week before the event
