Chipmonkey, ours have all been very reliable (well except the first one - but we'll skim over that particular aberration, as the other 5 have been ok).
Dh tinkers to keep ours up and running and we do have a great local mechanic who specialises in them, but the AA have been great with ours on the couple of occasions we have needed to call them. Like Stripey said though, if you ever do break down at least you are comfy and can have a drink and a snack while you wait to be rescued.
They really are workhorses and very easy to work on once you get the hang of it, hence while they are still around after all these years. That said, a good mechanic that knows his stuff about air-cooled vehicles and VWs in particular is worth his weight in gold.
It tends to be the bodywork rather than the mechanics that's the problem with them. We need a new left-hand (so right-hand drive) sliding door and they are like hens-teeth, you literally have to pay a grand to get a second hand one that is worth salvaging and then you have to pay to have it repaired/prepped and resprayed.
We take ours to Wexford every year on holiday. There's a big VW club Waterford way - I think, or at least there used to be.
