This price must be based on the “fanatic following” that these buses have. It is not based on what type of transportation you are getting.
One thing that bothers me is that I thought in 1972 VW buses were using the Type 4 engine with dual carbs. This engine is tremendousy better than the previous engines used. If you go up a few years and you will get into fuel injection. I happened to like the F.I used on the buses (much better than the latter but never used on VW buses CIS) I would not even consider a non type 4 engine equipped VW bus.
Perhaps the change to type 4 engines happened in 1973 but 1972 sticks in my mind. I have overhauled these engines before and found up to 4 sparkplugs just rolling around under the sheet metal. You must use a good magnetic sparkplug socket to change the plugs.
