I am new to the Mercedes Club and the forums. I recently took my 1999 E320 to a local German car repair shop and they gave me quite a repair list. I was sort of stunned because the car runs and drives fine. I had a few questions about some of the things they put on the list.
First, they told me that I should have the ball joints replaced, and the car itself only has 64,000 miles. The car handles just fine, though. Also, they told me that the spark pulgs should be replaced, even though the manual says that it could be done around 100,000 miles. The car runs fine, with no misfires, perfectly smooth.
They told me a few other things, but I just wanted to see what the consensus was on these items. I might make a new post with other findings. I have had the car for a year and it has had no problems.
