My 98 C230 is at 159,000 km's. 100K-miles is 161,000km's so I'm a quick trip to Jasper and back from 100K-miles.
It's been a highly reliable car with fewer problems than any other car we've owned. It's build quality is very high. Despite being a daily driver summer and winter (we put boulders on our roads, not sand...) the paint is shiny and looks great when clean. It's not used a single drop of oil, and for the most part feels like it's brand new.
340,000km's until I've got two badges on the grille...
(shooting for 250K seems too easy...)
