Thanks for the tip. I usually work on cars myself but never worked on a Benz before. I’ll look into the diagnostic system.My dad was known to say, "There is no car more expensive than a cheap Mercedes"...
So, with 187K on this, you will have things that need to be repaired. If you can do this yourself, and you are willing to invest in a Star Diagnostic System clone, so that you have access to all of Mercedes' workshop and service information, and will be able to test/diagnose yourself, then this could be a worthwhile car.
I love the W220. Love the looks. Love how it drives. Love the feel.
But if you're looking for a low cost ownership experience, and you can't do the work yourself, then you may be in for disappointment.
