Machine shop services service near Rockville, 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.

My car was making a rattling noise when I started it. They did an oil change and said that fixed the issue. Two days later it started doing it again. The shop is always too busy to diagnose and fix problems.If it’s not a basic or straight forward issue they can’t handle it.

Had been going to this guy for 15 years. In April 2014 Took my car in, guy kept if first 2 weeks, didn't address the problem. Afterwards I had to return the vehicle 6 times and he still didn't repair the problem. Took the car to the dealer who found the problem and said GAC had installed a cheap aftermarket part (not OEM) that was incompatible with the vehicle that doesn't take aftermarket parts. This guy ripped me off and refuses to reimburse me. Also I asked from the beginning for the parts he replaced, he lied saying I never asked for the parts. He did the same thing to my daughter. I would never take my car back to this guy after the way he ripped me off.

tely. I didn't even want to talk to the manager because I didn't even trust the guys to do work on my car after the way they handled this situation. They clearly knew they messed up. Never again. I will continue driving out of my way to Fairfax, VA to get supreme service even it it is WELL out of the way. I wasted 2+ hours at this place.

This place was recommended to me by a near by shop which I have gone to in the past since they were not able to service my vehicle at the time. Overall my experience was wonderful. I was greeted by friendly staff who were efficient and professional. The individual assisting me was attentive and he explained things in simple terms since I am not too familiar with service/mechanical issues concerning cars. I would definitely recommend this shop to my friends and family and anyone in need of a quality shop.?

I got a recall notice saying my airbag could deploy without warning and the repair department at Koons tells me not to worry about it. REALLY?
