A Subagon. From their website:
Our Subaru Vanagon conversions consist of top quality Volkswagon Vanagons, Syncros, Westfalias, Transporter Single Cabs and Double Cabs mated with the ultimate in reliable engines, the 230 HP Subaru SVX.
Yep, they yank the sexy 3.3 liter H6 out of the not-at-all-sexy SVX and plop it into one of VW’s infamous forward-control vans. And not cheaply either, this uber-clean example has an asking price of $39k.
Find it here on Craigslist and also on the Subagon site
