I would HIGHLY without any doubt reccomend Autobahn Foreign Car Repair in Oklahoma city, on 36th and Western. The phone number is 525-0600.

It is owned by a older gentleman that has been working on Mercedes for a really long time. My uncle has been taking all his Mercedes there since the 80's when he moved here. With my new one I call him and he tells me what to do. VERY trustworthy. He also works on other cars, but he is known for Mercedes.
