In the early noughties I ran a 1974 bay window as my only four wheeled vehicle alongside a motorbike for about two years. So it covered quite a few thousand miles for camping, shopping, going to the tip, and icy and snowy weather etc. The only breakdown was a snapped clutch cable, apart from that only basic maintenance was needed.
When I bought a static holiday caravan I sold it and replaced it with a 1971 1300 beetle which I kept about a year. This never broke down.
In my opinion in the classic world air cooled vw's provide the most diverse choice of vehicles (from trikes, through to buggies, bugs, campers etc), and are definitely the easiest and cheapest to home maintain.
As usual, buy the best you can afford, and if not already done make a couple of improvements like electronic ignition, twin weber etc.
