Most professional place I have ever taken my car! Great / knowledgeable receptionists, timely work, competitive prices. Online quotes that were actually accurate to what we paid. Great rewards program for their customers. Definitely the only place I will take my car from now on! Highly recommended....[more][less]

Your high praise means the world to the entire Gary's Auto Service team, Kyle. Thank you! :-) We deeply appreciate your high recommendation and look forward to seeing you again next time.

Gary's Auto Service is the most professional shop I have ever worked with. They tell you up front what's wrong with your car with no pressure to try and get any of the work done. They go out of their way to make you feel you are the most important customer they have. Their rewards program is the best I have seen. They have a customer for life. I have already told several people about the remarkable place....[more][less]

Thank you so much, Katherine. We are thrilled to have you as a life-long customer and look forward to seeing you again next time. Have a super week! :-)

I had a very pleasant experience with Gary's auto service. Nathan and Mike took very good care of the issues I was having with my truck and even saved me time and money on some additional repairs. I was more than satisfied with the service I received....[more][less]

I hate getting bad news, even when I ask for it. Please diagnose that noise... At least when Savannah or Nate give me the news I know it's the truth and it's what needs to be fixed. Thanks for your great work and honest information. Even if I don't like it....[more][less]

Thank you for your review, John. We appreciate your business and that you took the time to let us know how we are doing.

I was stranded out of state and had to leave my van in a parking lot and entrust my cousin to contact a garage as I got a rental car to get home. He was told by a friend that Gary's was who he trusted with his vehicles. The staff at Gary's coordinated the pickup of the van with him and we're very quick to email me the diagnosis with a follow up phone call after the weekend. Nathan was extremely helpful and talked me through my options. Although the damages to my vehicle led to a final decision not to fix the van, it was the staff that worked with me and helped me make the right decision. I would recommend Gary's to anyone in that area that needs an honest garage they can trust....[more][less]

Thank you so much, Dan, for your 5-star review. We appreciate you trusting your cousin and his friend who recommended Gary's Auto Service to you. Best wishes to you and safe travels.
