Hey Matthew,
great to see you back, if only to sell your van and to deal with cooling
rather than heating issues...
Of course you shouldn't sell yours, but you knew that, didn't you? Unless
you're upgrading to a 'known better' Vanagon, you'll lose on the deal no
matter what price you get. Because sometime in your life (probably within a
year or two) you'll desperately miss it and want to buy another one... And
by that time you're back to square one. BTDT. Get the sliding door fixed and
enjoy it for another 20 years.
Keep it. Stay on the list. Talk to us.
BRs,
Robin
