If this has already b een noted, please ignore - I didn't see mention of it.

I'm in London on vacation and picked up the October issue of the Brit magazine Mercedes Enthusiast. Good issue in general with a focus on coupes, and specifically an article on p. 32 by Reed Hitchcock on MB diesels in the US in the late 70's-early '80's. Good background on models available and when, reasons for diesel-heavy product mix, and a sidebar on the current enthusiast scene for these cars with photos and discussions with 4-5 diesel owners from the DC area. The article listed the URL to this forum for more information. Very cool, pick up a copy if you can, it's available around the US if you look.
