I never had a Westfalia, but I did have a '71 and '74 VW bus for a long time. That's where I got my real start in working on my own vehicles. I thought about getting a Westie a few times, but the thought of all the extra maintenance and things that could go wrong, over and above the issues of owning a standard bus, kept me from making the leap. From what I've seen, owning and maintaining a Wesfalia is more a lifestyle than a hobby.
Now that I've put it that way, I think I just ended up falling down a different rabbit hole of the same depth with the sohc4's.
