That seems to be the price that I see for these. I don't know much about them, except that there is not much power. Given that, they likely live for a long time, much like 240D's do. Check out the Diesel topics or search the archives for blow-by. When the engine is totally warmed up, (I have been told), you don't want to see much smoke emitted from the oil fill hole. Look to see how dirty the engine compartment is as well. Lots of soot, sludge and oil is a bad sign.
