I've been researching the mid 90's e300's looking for my first diesel. I hear mixed views on the cost of maintenance and how much regular attention they require. Can anyone with more experience than I give me an average yearly cost of maintaining one of these? (I'm new to the scene, so I will be just learning how to do any of it myself) Just a ballpark is fine, hundreds or thousands? The help is greatly apperciated.
