Yep, high tech Oracle junkie. Gives me something other to obsess about than the beloved MB 400e.
I bet that 240d with a speed is much better than the auto. My parents had a 240d. A great car, too slow, probably really WILL last forever, however. Why is it that the slow ones seem to last longer? Wouldn't it be great if the ratio of engine longevity to horsepower was direct instead of inverse? The faster a car was, the longer it would last. We could all justify buying a 500e that way.
I do not have personal experience or scientific evidence that changing the oil at 7k is any different with regards to the longevity of a car than changing at 3k, do you?
I would love to see numbers on this subject instead of trusting the manual.
