$20K? sh!t I got lucky. Got my 1987 Vanagon in 2006 for $1800, got the Subaru EJ22 conversion for $9K in 2008 with 125K miles on the van. Drove it from Santa Cruz to LA, over the Grapevine, in July 2019, packed full of surfboards, LP records, and a dog, got 24mpg, and did not have to drive in the truck lane. Mine also isn't a Westphalia, it's a Wolfsburg "Weekender;" bed, Murphy table only. No wood or water hookups, it weighs way less than a full Westy.Subaru conversion? The engine commonly used for the conversion is now old itself and hard to find low mileage examples. Also, the California legal one does not have much more HP than my engine and...the conversion costs +- $20,000
I like Bob's idea to list it for $35,000 and see what happens...
There is a place in Santa Barbara that might do a conversion to Subaru for less than $20K.
