I believe if you can establish that the oil was changed regularly and the other maintenance was done, these cars will run for a long distance....I have been in Mercedes diesels in Germany that were used as Taxis with over 800,000 kilmeters on them (over 500,000 miles) that were running on the original engine and tranny. I have also personally run gasser Volvos to 300k+ before I traded them in on other cars; that tells me that mileage is inportant, but maintenance is EVERYTHING. I plan to run my 300SD to over 1 million miles....but I have a spare engine and tranny put aside already, just in case.......
