Any rust warrants further inspection. I hear the AC is semi-expensive fix. I wouldn't know since I'm fortunate enough to live in an area where it's superflous. You could fix it, or go without. I drove in Georgia without AC for years when I was a poor student. The automatics in the 123 chassis cars are usually pretty durable, but maintenance matters. Based on what I can see in the ad, it looks like a decent candidate for the cheap wagon club.
