I assume you mean MERCEDES diesels? My 300D was bought specifically to use for long distance travel since my wifes 89 Jetta was not suited for that and driving the work truck was not economical. Then the wifes car was totalled and a 03 Jetta TDI fills the space in the garage. It is a far better distance car than the 300D will ever be IMHO. Quieter, reasonably comfy seats, and 50mpg at 75-80mph. Better in the snow too. The MB was always needing something, usually before a trip. It still needs the valve job redone, the ACC looked at, etc. etc. So most of the time it just sits. I do drive it once a week or every other week but thats about it. Since the whole fleet is diesel I drive one every time I leave the driveway. RT
