So I've been lurking for a while, reading about the cars. Now I've made the decision to buy a diesel W123 or W124 to replace my '93 Mazda Protege. So far I've looked at '92 300D, an '84 300D, and an '82 240D. I'm about to post in one of the other sections asking for advice on what I've found. I'd really like to get one with minimal rust, especially since I'm going to be living in Dayton, OH and then DC where it can easily go from bad to worse.
