They can be to start with, I had the same years ago with another club back in my Renault 5 days. My first meet was actually in my home town of Southend along the seafront, I turned up in the 5 GT Turbo all enthusiastic and eager to meet fellow car owners only to be pretty much blanked after introducing myself! But I just hung around and cracked up the odd conversation with a few people and it went from there. The Internet wasn't as profilic as today but people would still post about trackdays they'd be attending so I just went along, again striking up conversations helping people in the pits and just getting to know more people. It happened a few times and now about 13 years later they've become genuine true friends.
We've been abroad, rolling road days, trackdays, car shows that don't involve Clios, curry nights, beers. We can all make it what it is, everyone we meet don't have to become friends but we all share the same passion for Clios and cars.
