82-85 300d's are the best and the cheapest for wvo in my experience, their fuel system can take a lot of abuse and will run on practically anything, as long as you get a turbo model you shouldn't have any altitude issues either. the only real down side is they don't like short trips (just like most pre 90's diesels) and they are all auto but with a light foot and regular maintenance you can still achieve mid 30's mpg. if UFO's is a four speed you might want to think about that!
