I agree with everyone who says to sell the van whole.  I would be more
worried about getting enough people to come get parts off if then finding
one motivated buyer to take the whole thing.  Put it up on the Samba or even
eBay with a reserve.  Someone would be glad to rescue it.  Just be specific
and honest as to why you are selling it and the right person will come
along.  It's in too good of shape to part out.  It might seem like a
nightmare in expenses trying to play whack-a-mole with with it fixing issues
but for a knowledgeable buyer that won't be a problem.

I could not imagine owning a Vanagon and not being able to work on it
myself. I would go broke if I had to pay a mechanic for everything. In the
past 18 months alone I have put in a new radiator, front heater core, 2 long
coolant pipes, replaced the gas tank, painted the van, installed front brake
calipers, new starter, new catalytic converter and diagnosed poor
performance and bad gas mileage issues.  Of course I had tremendous help
from the list members here but there is no way I could have been able to
afford paying people to do all that work.  I did have someone put in my
clutch for me, I was too squeamish for that.

Still waiting for a 20 mph wind to turn my new windmill....
