Steve repaired my 2008 ml320 cdi which was in limp mode. He placed the car on his scanner which is the same as the Mercedes Dealer and tracked down my problem . Repair was quick and a very reasonable charge. I read many horror stories of dealerships replacing many sensors and ending up with a huge bill. The dealership was charging 290.00 just to scan the car . Stevens charge was 99.00 and he printed a report and went over each area scanned with me . Very knowledgeable guy. I had him change my diesel air filters and fuel filters and again very reasonable charge and a neat job. Definitely my auto guy to go to from now on.
