What to look for when buying an A body?

This area is pretty dry. I bought my F-150 body there, and there is very little to no rust and I couldn't pay the guy fast enough for it. Its on the other side of the Cascade Mountain Range. If it spent the majority of it's life there it should be fairly low on rust. That said, do check it over for rust or body damage, run the Vin, and take pictures, because it helps when you leave and go "Oh yea, I forgot to look for or at that one thing..."
Yeah, east of the Cascades in the Pacific NW seems to be a good place for cars to not be rusted. I have considered several out there. Shipping to VA on an open carrier runs around $900-$1000 which is cheap compared to a lot of rust repair.

Oooops....hope I did not just run up the cost of old cars in the PNW!
