If you like to see the same faces behind the counter and in the shop, then this is the place for you. The owner, George Winkler, opened this shop 30 years ago. Two of his technicians have been with him for the last 25 years, along with a service adviser who has been there for the last 20 years! That stability has led to excellent customer service as shown in their outstanding Net Promoter Score. Winkler Automotive has everything necessary to get your vehicle repaired right the first time.

I've been going to Winkler Automotive for 7 years. They are honest and not pushy. I only had one time where I had a tough experience, but they went out of their way to make sure they fixed the problem.

Their front office staff and their mechanics are very friendly and very honest. George, the owner, he works down stairs at the counter. He is hands-on and very good. He makes it a home and makes it a good atmosphere.

Great reliable service!! I have been going to Winkler Automotive for years and one of the best things is they are honest and trustworthy. They never try to sell you more than what you need. The Customer service is excellent!

Winkler Automotive Service Center does quality work at for a reasonable cost. George and his team are courteous professionals. I’ve been going to Winkler’s for over 20 years (they were in their old location on Diamond Avenue.) I returned today for the first time in a few years. They took the time to answer my questions and I’m sure they would do the same for everyone. The guys are honest, top notch mechanics - a rare breed these days. They did a great job on my 2011 Acura MDX and at a price much, much lower (about 30%) than the dealer estimated for the same services. I have, in fact, just a few minutes ago recommended them to my neighbor who was trying to find a place to repair / fix his leaking radiator. One last thing, I have always trusted Winkler Auto Service to “tell it to me straight.” What do I need? When do I need it? Today, next month, six months. They do. I think they truly have my best interest in mind in keeping my car running properly.

I've been a customer of Winkler's for over 20 years. I continue to do business with them because they are honest, highly capable, and put my interests first. You can't do any better than Winkler's for the best repair and maintenance services.

After my dealership closed, I was looking for a new facility to take my car for service work. I found Winkler Automotive in Gaithersburg. I was impressed by how clean and pleasant their facility is. Winkler Automotive has a great staff with great mechanics who are very knowledgeable. They repaired my car properly and at a more than fair price. If you need to wait for your car, their reception area is very comfortable with a variety of magazines and complimentary coffee is available. They also have a shuttle service if you prefer. I would definitely recommend Winkler Automotive to anyone who needs a reliable, honest repair facility. They also have a website,, where you can find information about the work they do. Needless to say I have found my repair shop and will refer everyone to them.
