I called the owner (a dealer out of Portland, OR) yesterday and he says it was in an accident last year and the insurance company salvaged it. The owner, at the time of the accident, then bought it back from the insurance company and had it rebuilt. I asked how extensive the damage was and the dealer said it was very minor (as they alway do). The dealer wouldn't tell me if he took it on on trade or if he bought it at an auction.
Not sure if he was just having a bad day but the dealer wasn't super approachable. I asked for more pictures, specifically of the undercarriage, but I haven't seen anything yet. I'll post them here if they ever show up.
