An interesting article. To be fair most of the problems it mentions are not specific to car clubs, they can happen in any group. For instance, the AGM of The Society of Genealogists a decade ago was a blood bath!
A lot of them are specific to classic car and bike clubs - its the differences between the rivet counters / concourse types and those who just like old cars.
Dont get these issues in my sailing clubs because they arent focussed around just one specific make in the same way that many car clubs are. Instead just the usual clashes between people of different social and educational backgrounds that you get in any organisation.
