I recently did business with Mark at Sun Valley Mercedes at it was a pleasure. He did excellent work at a reasonable price and a quick turn around time. They also have a dismantling business attached so you can get hard to find parts for you car as well. Check them out at:

You will not be disaapointed.

Mike knows his stuff, even if his front office guy doesn't. Prices will be more than eBay or nearby pick-n-pulls, but for harder to find stuff, go there.

He did the tranny on my 1991 300CE. Quick, easy and great price.
