It is not unusual at all to see these cars (98/99 E class turbodiesel) with 250k+ miles on em still going strong.

The one I have has the following issues right now:

a. steering rack leak
b. rear windows don't work

and I just finished replacing the #5 glow plug.

The wife drives about 10k miles every three months. Because of the amount of miles she racks up I believe the 98 E300 is one of the best cars she could be driving right now.
