If you plan on going back, see how much they're willing to sell the whole thing for.. it
does look like its in great shape (although apparently most of the parts seen in the photos have been taken by you), and I'd be willing to make the trek up there with a trailer. Another question I'd have would be how easy it is (if its at all possible if that car spent the last part of its life in NY state) to get that VIN back on the road. That is a huge deterrent in this frickin' state, and I think if you find something like this in NY state, you should do exactly what you did: pick every single thing from it you can.
Too bad you don't have a garage ::shrug::
Does that guy from Fredonia have a garage to store your crap in? I forgot his forum name but he posts pretty regularly and I think he has a Scion. I'm sure there are other trustworthy Buffalo-area members that would be willing to help you out here.......
