There is a 90 Vanagon on EBay that is not an true weekender. 
I looked at it and here is a report:
 
 It has one power window and one manual window door. Wires hanging out are
to run window.  It has not run in 3 years.  The tray table was cut out of
another van and was bolted in place. Leaks oil bad. Has rust on the front
under the windshield and on the back hatch rust under the rear glass.  Dog
hair inside is all over.  A rather larger Black widow spider guards the
front right wheel well. Paint is in bad shape, parts that were painted over
show.  There is a small dent on the right rear corner just above the bumper.
Will need some brake work to make it stop. Has an after market cruse that is
missing the main unit at the front. Has bench seat for center.  Missing the
rear seat front panel at the floor.
Since it sat for three years fuel injection system will need to be cleaned
or replaced: Pump, injectors, line, filter, tank removed and cleaned, (Rust
inside?)
Braking system will need work: Rust on rotors, drums possible replacement
needed, 
 
Front bumper is in OK shape.  Questionable about the engine.  Does not look
like a head gasket leak but the distribution pipe end blew out easy $40 part
fix.  But it has sat for three years with coolant/water inside do not know
shape of inside engine  Stud rust is possible, probably will need to be
taken apart to make sure a stud does not pop somewhere...flush system and
see if it is rust colored water coming out, if not then probably is OK and
does not need surgery.
A/C system is new but sat for 3 years unused do not know the condition of
the seals.
Auto tranny is in unknown condition.
Exterior lenses are unbroken.
 
Would be good for parts or a LOT of work to get it in a safe running
condition.
