Wow, we'll just miss you - we're going to be in Utah in a few weeks from now. If that 61 is located there (where in Utah if I may ask, out of curiosity?), then you at least you should have a very good chance of getting a pretty much rust free car. Although, on the negative side, Utah does use salt on its roads in the wintertime. I would definitely check out the undercarriage,wheel wells, etc.
Since we're discussing tire sizes, I'd like to take this opportunity to ask a question - I want bigger wheels on my Fury than 14s - I'm thinking maybe going with 16s. I wonder what size tires I should be looking at that would fit underneath/match the original radius', etc.?
