Emissions testing service near Gaithersburg, MD

Superior has been my garage for over a decade based on a recommendation from another satisfied customer. Rob & Bob do a good job listening to the work I want done, describing the work they identify that needs to be done, and then completing the work on time. I recommend them to all my friends.

Great people/great atmosphere. I had my car worked on here and they accommodated me with a loaner vehicle. Also had a quick and accurate estimate, reasonable prices, and performed the services. My car has been running great and I will surely be returning to them for future business.

Charges me $50 to clean corrosion off of my battery.

They have started to much overcharge for all services. Recently i had a oil change service and inspection and they changed cabin filter and charged ke $200. Even dealer would have done for much much less than them.

I visited IMA Motorwerke for a Prepurchase Vehicle Inspection. There were a bunch of fault codes that could not be figured out as well as a vibration for a previous inspection. While I did receive a report with comments and recommended work, it did not get to the heart of what I originally requested. When I asked and followed up, nothing additional was found. It was not until I took the vehicle for an inspection following vehicle purchase that I learned of a host of issues that were not previously identified. There was an exhaust leak, the vibration at the rear of the vehicle was a much larger issue requiring additional diagnosis, the headlight seals were busted, and the remaining fault codes rendered parts of the vehicle inoperable. Had I known the majority of these issues beforehand, I would not have purchased the vehicle. It is disappointing that I was charged $332.80 for the comments and recommendations that I received, and the saving grace for the issues that allowed me to get from under the purchase from another mechanic’s shop for free.
