Thanks for the comments! Car was in California 1986-2001. I bought it from an individual in New Hampshire who owned it since (however, it was garaged and not driven during the winter). The rust below the rear-window trim is all I've seen. Floor pans look amazing. Here's a picture of them (I took this picture when I had a puncture in the return fuel-line). I need to remove the window trim to assess the rust better if anyone knows a good link which illustrates how to remove it properly.
