Thanks everyone for all the advice!
I ended up making a deal on the car:

But decided against driving the car back, too many unknowns and the car is not exactly 100%, and 35 years old. So I had it shipped. Because of the damn winter we continue to have, I chose to go with enclosed transport, and chose TFX - they did a great job, easy to work with, and did door to door service. I would never ship a car any other way again.
This western car was obviously never winter driven and really, really, really, clean and rust free. I feel pretty lucky - the car is exactly what I wanted, for much less than I was budgeting for a clean unmolested SC.
