As an aircooled owner I sometimes believe this to be in fact the
watercooled list, since at least 90% of the correspondence seems to be
about these models, the only (I think) vehicle to ever blow an engine
during a Road&Track magazine long-term test (4/'85).  This is not a
complaint about this great list, just an observation.  Probably, in
fact, the larger percentage of Vanagons built were watercooled.
