I have an old Mercedes 450 I picked up that needs some fairly extensive work. Anyone have any experiences with OKC area Mercedes mechanics?

I've gone to Silver Star Imports in Edmond (albeit for their Toyota/Lexus service), and have been pleased with their work...

There's also another MB service shop in Edmond called All Star Motors, but I don't have any experience with them.

I use Central Star Motors on Reno Ave. downtown. They do only MB. I've had good luck there.

Silver Star. Used them for long time on multiple cars, yrs. and models. Always been fair, and good.
