We have never been able to get service at the VW dealership for our 1975 camper, even when it was only 20 years old, but there are places that will provide service for older VWs. It may be best to find a shop (or shops) in advance so that you know where they are in case of need, and then visit them for a simple check-up so you can get a feel for whether you like them or not. We have a couple of people that we contact when there are issue that are outside of my ability to deal with easily, but overall we don't worry about it that much. As with any vintage vehicle, keep the maintenance up, be aware of anything out of the ordinary while driving, and develop a contingency plan for what to do in the event of a breakdown - then have fun and enjoy your camper!
