$600? OMG, I would have strapped on a diaper and driven 3 states away nonstop for that. It looked to be in fantastic condition. My condolences on being 2nd in line. That sucks.
I'm hoping to find the title in my dad's house somewhere. If not, that might mean that the teenager he bought it from didn't have it. The kid was a bit of a neighborhood low-life and it wouldn't surprise me if it had been stolen. I've always been afraid to apply for a title for that reason. It was purchased 35 years ago and if there was a hand written bill of sale, it's long gone. Is there any statute of limitations? I always envisioned the DMV telling me it was stolen, then watching as some distant relative of the original owner shows up at my house and hauls it away, while I lie in the street crying like John Boehner chopping onions.
