Found this for sale (locally) for $800... I wonder though if the engine is destroyed. I think this one is the "rod bender" engine isnt it? I wonder if that is what has happened? Says that it is leaking oil, lost power. Hmm.

"1990 Mercedes Benz for sale. Many new parts. Body in great shape, no rust. Almost new tires. Gray leather interior, power everything, Sunroof. Second owner. It is a 350SDL turbo diesel. The car has 199573 miles on it. This was my daily driver until around two weeks ago. It will start, but would need to most likely be towed. Leaking oil, lost power, could be something simple, not really sure. Purchased a new car, need to get rid of this one ASAP! $800.00"
