On 3/16/2025 M.G. Bumpus had this to say:
Great knowledgeable service with a smile.....

On 4/24/2024 Sharon Judd had this to say:
The dreaded engine light went on in the Toyota Matrix and our mechanic said take it to the dealer. The dealer wanted $200 to access the issue and most wanted about the same. I knew the issue was related to my trans so I called ATS since several people at my gym recommended them. They did an amazing job for me. My car drives like new. The only issue, ATS is VERY busy and there could be a wait, but the wait is worth it. Very knowledgeable and honest. Highly recommend.

We just want to say what a great job Mason did to get our Denali back on the road, where two other shops were unable to get it done. He went above and beyond and we are very thankful for that! A thank you to everyone that’s had a hand on the repair. We give you a 10/10. And we will highly recommend your shop. Kevin & Connie Vanderlinden
