Autotech Auto CenterI own an 07 F-150 XLT (5.4 Triton Eng). 3rd owner with 154,000 miles on it.

Thanks to this team, I have affordable and effective care of my truck to avoid having to drop thousands of…
Autotech Auto CenterI really appreciate they were able to get me on the schedule, earlier than expected. I really love the professionalism of the associates and how clean they keep the customer area.

The entire team is fantastic - courteous, friendly & truly concerned about my safety . I won't take my car anywhere else! Thank you Autotech! Donna
Autotech Auto CenterIt was our first time at Autotech, we had to get our fluids topped off and our brake pads replaced.

Autotech Auto CenterI went to Auto Tech because I had received a flyer in the mail for a great price for an oil change. The service was wonderful. Everyone was so kind and no one was pushy trying to get you to have other work done. I will definitely go back.
Autotech Auto CenterI took my car in having already had a diagnostic at the dealership. They put in their time and expertise to diagnose the problem themselves. The stability and performance of my car is like night and day! I was very happy with their continued communication and the price was comparable to other shops in the area.
