I don't see how organizing GTR only events within SAU VIC would be any more wank than organizing GTR only events within the broader import community...which is effectively what you're doing. It's the exclusive meet with a not so exclusive car that is the wank factor. People wouldn't want to tarnish a group of Ferraris by turning up to a Ferrari meet in a non-Ferrari...because they are rare, exotic and expensive, and can hold their own for people's interest at a meet. They are also brand exclusive instead of single model exclusive.
But when your single model car can be bought and driven by this...
...and you make it exclusive...
Then you look like wankers.
So what happens when someone no longer owns their car? Do you banish them and refuse them coming along to an event in another car, despite having been friends with them for years and sharing many experiences with them? Because you do realise that's how SAU VIC evolved into a many model club, don't you? And that we as a club would have died off years ago if we stayed Skyline only? Meanwhile we are one of the oldest import clubs on the scene and I've seen a lot come and go over the years.
To me, exclusive model clubs are a short sighted dream that inevitably comes to an end when members move on, models become less popular due to rarity and being old, and nothing is done to keep the club moving with the demographic trends towards other vehicles. So enjoy it while it lasts, I guess, but the rest of the import community will continue laughing at the Ferrari wannabes...
