I just bought my first MB *and* my first diesel car today! It's a 1984 300SD, metallic silver with black leather.
After spending about an entire (work) day reading your messages on this forum, I decided I was going to buy the car. It was one I found in a local car trader magazine and ended up paying $1800 Canadian dollars, which works out to about $2400 USD.
The car has 415,000 *kilometers* (257k miles), with a rebuilt engine with 60,000 km on the rebuild. The interior is very clean with just a small tear on the drivers seat. Body has some minor rust, a couple spots where it's starting to bubble through near the wheels, but not bad overall.
I'm still not sure what to think

I think I got a good buy. We'll see how much it ends up costing me over the next year or two though. Anyway, this forum is great and I'm looking forward to using the vast knowledge gathered here to help me keep my car running smoothly!
