By understanding your car--even if you can't do the work yourself, you'll be able to understand the kinds of things that can be done easily by any skilled mechanic and certainly an MB mechanic. That's one of the things this forum does is allow us to understand, learn and share our collective knowledge and keep it alive.
Things like changing a radiator, oil cooler, nearly all suspension and brake work, body work of all kinds are the kinds of things that are "easy" for a skilled mechanic or shop.
It's when we have these complex fuel injection issues; fuel delivery issues, linkage adjustments, transmission adjustments, and peculiar things like this, that are pretty much related to this car only, or cars of this vintage that the old world skilled and experienced mechanics come in very very handy...
Sometimes the issue is just figuring out where your real problem is, that is the challenge.
Personally I have not been to a dealer since my transmission woes of July 2001, when they told me to "get that thing out of here" when they saw the fluid leaking all over their pavement at the Mercedes dealer in Lansing, Michigan. But nearly all the mechanics I have used around here have worked at dealers.
Thankfully I've got quite a few skilled mechanics in the area, and Dr. Benz is only a 90 minute drive away. Really, around here I think this is one of the better places to own a Pagoda!
