What Tooele Drivers Say
“These guys are incredible! My car sat for two years without running. I was expecting to spend a pretty penny. However, these guys got me back in my car for far below what I thought!! Not only that, but they got my car back to me in literally 24 hours. An oil change and a battery was all that was needed. These guys could’ve been dishonest and charged me for all kinds of things. But they have proven themselves to be honest and professional. Thank you so much Master Auto Tech!!!”

“Jason, Heather, and the whole crew took a deep dive into my old Bronco and found the solution that NO ONE else could. I couldn’t be happier. I drive 45min one-way to bring my vehicles to this shop. Price and service are second to none.”
Daniel Frederick
“Outstanding Service!!! This was my first time taking a car to Master Autotech, and i can safely say that I’ve found my new shop. I tried getting my clutch replaced at a couple other shops first, but they didn’t seem to want the job. (They were) super easy to work with right away, and they made room for my car immediately. I got my new clutch, as well as a couple of other things that I’ve wanted done for a while. I will definitely be going back!”
