Thanks for the links, Josh! Spent a lot of time reading and am down to WD-40 or Waxoyl... probably a combination of both. Likely to blow the wad and get the Waxoyl done by someone with the right set of application tools (to get in the crevices of the frame) - at least the clear - and then use WD-40 on bushing areas/suspension, etc.
Stephan - a lot of what Abraham said. They're surprisingly well built - over-engineered in many ways - and this one, with 250k+ miles goes down the road as smoothly as my '16 Silverado. In fact, it doesn't vibrate like the Chevy does when the cylinder-deactivation takes over!
This one will be moving out, along with my brother, to Nantucket - where he can drive on the beach. Full-time 4WD, a granny gear, and a rear locker - with good Geolander tires (PSI set to about 10) - should keep him under way. When my family goes out to visit him, the 7-seater functionality will shine.
I've always been anti-minivan. To such a degree that I thought of marketing the bumper-sticker, "BEWARE THE MINIVAN" because they represent the pinnacle of distracted driving. Yet, even since the mid-80s, I've applied an *asterisk* to the word - minivan* The asterisk is for *Vanagon*. I just don't see them in the same light.
If you get a chance, take one for a spin!
