I bought this one in 2005 and it had 98,000 on the clock. Less than 14k with tax and tags.
I change oil based on the onboard computer Flexible Service Schedule - it tells me when to change the oil. My driving style gets me anywhere between 15,000 and 18,000 miles between changes. Previous owner did same. Both of us only used Mobil 1. I've been using Gold Cap for the last 100,000 or so. Grey cap before that.
So those that say change oil every 3,000 miles - I say Bunk!
Everything else either gets replaced based on the Benz suggested service, or if something starts acting funny. Only time I did not follow the schedule (I skipped over it by accident) was front wheel bearing service. I missed them by 50,000 miles and lost the rf bearing, so I had to get a junkyard spindle.
Yes, I love my Benzes - even an "unreliable" one is more reliable than most American junk. Sorry American car lovers. I was one once. No more.
