I think $10K is more unusual than typical. I have a 98 E320 4matic wagon that currently has 110K with no issues other than a minor trans fluid leak. Easily solved with a new pan gasket and o-rings for some sensor on the side of the case. Total bill was around $160 at my indy including several liters of the expen$ive trans fluid. Great car, solidly built - as long as you don't drive it like a teenager trying to impress his friends, should be reliable transportation for years to come.
