I have to throw my two cents in about the best diesel. Having owned a 1985 300SD and a 1992 300D 2.5 I can say easilly the 300D 2.5 was the better car.Although I had no real problems with the SD the D was much better in acceleration ,fuel economy,quietness,drivability,and had the newer amenities such as airbags etc.
Wish I was as pleased with my current 140 S Class diesel...buts thats another story
