used to be just club events and you had to have all the doco for that, became too hard.
it's now 90 days and you have to fill the book in prior to departing as above no book unrego.
car still has to be RWC.
car has to be more than 25 years old
thee is a very limited number of clubs that you can be a member of and you have to go though them to get it,
not like cams where if you are a member your are automatically eligible.
So if you have an old car you hardly drive then it all good.
but as a rule they make it a pain to discourage you, and you only save a couple hundred a year.
I looked at it for the stang but decided full rego was easier.
