Each to their own and you are 100% entitled to your own opinion and views Richard. And in no way would i try to convince you otherwise. I'm sure you're big enough to make your own decisions.
However:
In reference to your post - I would argue we are a little bit more than a 'forum' as you put it though....
The 'How to's' section here (Access to which is only gained by paying members I will add) is quite the wealth of knowledge: and I would think an unrivalled collective source of info regarding various and numerous tasks / jobs / maintenance on these cars.
'Fairly' specialist cars i might add - and a car that many-many site users have previously come on and invested the minimum £5 joining up here: in order to hopefully buy from a dedicated and enthusiastic site participant: rather than from a run of the mill former owner who knows nothing of the quirks and traits of these cars and what is required ref owning one - to keep it sweet.
From looking around you will have no doubt seen the spirit of this place - and I've seen info shared, spare parts offered freely, unbelievable selfless acts and lifelong friendships made here. Genuinely.
As enthusiasts - meet ups, rideouts, Regional and National get togethers, track days, days out and even driving-based holidays have and are all organised here for and by the membership.
Apart from that the banter, ethos, friendliness and informative daily topics here are second to none. I've been a member of tens of forums, helped moderate one other (Not car related) forum, and also maintained my own forum at one point. And I have never known such a well run forum frequented by such amiable and like minded members.
I will also add - that all involved in the running of this site do so voluntarily and make not a single penny from any membership fees. It is on the most part ploughed back into the sites substantial daily running costs, giveaways, compititions. yearly meet fees (French Car Show stand)!etc etc. So on the back of this - it makes no difference to 'us' if you choose to join or remain a freeloader as appropriate if and when you find a car. And I don't say that lightly or to mock you - but as a site with ongoing costs: that is the harsh financial reality.
Good luck again in your search, and i hope some of the above has been helpful.
