My wife and I just had our first kid and are looking to buy 1980's Vanagon Westfalia. What are some of the most common problems we should be aware of, what should we look for? This may have been already posted somewhere here, but I'm new to the forum and didn't see it. Please don't reply with Westy's for sale, just looking for advice and research right now to make a good decision. Any information would be helpful! Thanks.
