“I highly recommend this shop. The service they provide is excellent. The staff are very professional, knowledgeable, and most of all honest. They truly care for their customers. Will definitely be a loyal customer for years to come!”
“Amber is such a great technician!! Everyone else was very professional and friendly. Quick service !! Nobody pressures you for additional service. They give you advice recommendations while they are at it. Highly recommended them. Best place I’ve had service done for Jeep. 5⭐️”
“The staff was friendly and patient. The inspector found issues we were unaware of that were actually kind of important. I'm not sure what else to say, they have a bi-lingual receptionist in case a language barrier may exist.”
“As some people have mentioned parking here is a nightmare, but these guys get the job done. Friendly, competent and, most important, honest! They told me the problem in my car was fuel pump, and that the warranty should cover that, instead of just replacing it and charging me a fortune. They did the diagnostic and didn't change anything. I highly recommend them!”
“Dan is THE MAN! Let me tell you! OMG, this guy is not just super friendly, but also extremely knowledgeable, honest, patient and helpful. He gave me a full explanation of what was going on with my car. I did some research before hand and he didn't make me feel like because I'm not a mechanic, that I don't know anything. I was going to get an oil change this weekend, but my car needs to be worked on for tire rod issues, which I will bring back to Dan to be serviced on Monday, and I decided to wait until he works on my car to do the oil change. There's no reason to go anywhere else! This guy is the REAL DEAL and he has years and years of experience! I'm so grateful to have found this place! Happy Happy Happy!”
“Winkler provides EXCELLENT, PROFESSIONAL, HONEST service! It was the ONLY place that ACCURATELY diagnosed and fixed the issues causing my check-engine light to be on and my car to flunk DC inspection. Three other highly rated shops charged me diagnostic fees; one claimed to have fixed the problem (it had not) and the others gave me long lists of supposedly “urgent” repairs that would have cost megabucks and, as it turns out, would NOT have addressed any of the actual problems. Luckily, I called Winkler. Jeff, Winkler’s manager, was incredibly professional, patient and helpful. He immediately questioned the pricey fixes the other shops had pushed and assured me Winkler would get to the bottom of and repair whatever was going on. And it did! As promised, Jeff and his team thoroughly inspected my 2008 Honda Element, found the real culprits (missed by every other shop), repaired everything for a very reasonable price and kept in touch with me every step of the way (so there were no surprise costs at all). The result? My car sailed through inspection and runs better than it has in years. The bottom line: Winkler is the ONLY place that took the time to truly solve the problem, and it did so with integrity, expertise and fairness. I HIGHLY recommend It for outstanding quality, honesty, fair pricing, and professionalism. Winkler is the only place I’ll take my cars from now on!”
“Ethical and honest. Confirmed that a bogus list of recommendations from a chain shop were not needed. Don’t waste your money elsewhere and come to EPR.”
“I'm so happy with Premier Auto Clinic! They are professionals who do their work quickly and perfectly. Their prices are wonderful and their service is top notch. I can't recommend them enough!”
“As a loyal customer for many years, I can confidently say that Hillmuth exemplifies a premier service organization. Their team consistently demonstrates remarkable flexibility and an unwavering commitment to professionalism.
This dedication to excellence is evident across the entire operation. At the front desk, Scott masterfully manages the client experience, providing clear, proactive communication and updates. In the service bay, the truly talented engineers apply their deep expertise to every vehicle.
Special recognition is also due to the owners, Matt and Billy Hillmuth, whose visible presence in the shop sets the standard. Their professional and courteous interactions with all customers reinforce the culture of integrity that defines Hillmuth.
From start to finish, my family and I have always felt valued and treated with tremendous professionalism. We are, and will remain, loyal Hillmuth customers.”

“They have done a amazing job on my wife vehicle. They are very honest , and straight forward. They work on any or every issue, not just on transmission. After 5 years going to same mechanic, Trans Tech became my go to shop, the FACT they have the skills and knowledge.
I took my wife vehicle expression I needed to replace transmission. Ron, very nice guy, said my transmission was not the issue. Squirrels chewed my battery cable among others wires, was able to trace and repaired. Also found out there was sugar in my fuel pump injector. They were able to clean it up and replaced. Now the vehicle runs better and smoother than had been for 2 years.”

“Went here on a busy Tuesday morning for MD Safety Inspection. From Rakhee (owner), to cashier to service lead: Erick, I was met with kind salutations, friendly banter, and empathy. Haven't seen this attentiveness since I lived in LA, where the car culture is strong and service centers know the value of earning my business. I miss the warmth of LA, but gladly appreciated the warmth of Erick's smile, gratitude, and laughter. I'll definitely be back in the future.”
