i'd buy it if i didn't live in CA. Love the OM612 and this looks like a fairly solid low mileage truck ... not a lot of rust visible in the pictures either. If it runs, the seller is really doing himself a disservice presenting the truck this way instead of cleaning it up and fixing the headliner at least.
It sounds like it's already titled in the US so it shouldn't be as big of a hassle to register in the less stringent states. I'm guessing it'll get to at least $25K-$30K, which is not bad considering what some of these run of the mill Europa G500s are selling for.
