I expected to have issues with a 7 year old car but it has been excellent. I drove it 23,000 miles this year (hwyway and in town) without an problems. I had one catyltic converter replaced under warranty. I had a two dash light bulbs burn out but the dealer sells the tools to quickly remove the a/c and speedo units so I did it myself for $30. The head light lenses need to be buffed out ($75) and it would look much newer than a 99. It uses oil, but MB says to expect a quart every 625 miles but it does much better, around 2000 miles. I am not totally sold that 0W40 mobile one is exactly right for this car even though that is the MB recommendation.
The driving pleasure. The still like new black leather interior,
