I own a 99 300 Turbodiesel which I purchased new. It currently has 23K miles and has been trouble free thus far. I particularly enjoy the turbo "rush" around 2500 rpm. The engine is very quiet and stingy on fuel. I get around 30mpg in town and 32-34mpg on the highway at 75mph with the a/c running most of the time since I live in FL. Most people will never notice this car has a diesel engine...except for "glow plug wait" before starting. If only my ML 320 had the same engine......
