Hi Max,
There's the Cobra Car Club of Victoria (CCCV) and the Malbourne Cobra Owners Club (MCOC).
The CCCV is the original Victorian club and the largest. The MCOC was formed a couple of years back after a couple of members had a falling out (it was a sad time as no one wants to see disagreements in a club).
The MCOC seems to be dominated by guy's with Laurie Bongalias's kits so if you are building one of his cars it may be a good one to join.
That being said there are still plenty of Laurie's cars in the CCCV so the support is there too.
I'm a menber of the CCCV as are probably most of the Vic members on here. I think the MCOC guys have their own area of the net where they hang out.
Personally I like the CCCV. They are a nice bunch of people and there are plenty of events of all types to keep you ammused. There's a big base of technical knowledge in the club on all types of Cobra. There doesn't seem to be any bias for or against any type of cobra either. Plus there's enough of us dark siders in the club now to keep these ford blokes honest too.
Come and see us at ShelbyFest at Winton next weekend and judge for yourself.
Cheers
