What our customers say about us

Had a great experience! Will certainly be back! Courteous, professional, and knowledgeable. I think we've found our new auto shop! Thanks!
Christopher Still
Our first time experience with Sargent Auto & Diesel has been a good one. They worked on my '97 F250 7.3 diesel. Nice to have a trustworthy Family run business that cares about the quality of Service they provide.
Joe Myers
This is an awesome shop! Always efficient and they never try to “sell” you repairs you don’t need. They are very thorough in everything they do and reasonably priced for top notch mechanic work! I will be a customer for life!
Ken Smith
By far the best service, the sweetest people ever! They didn’t try to add any extra nonsense service on. Made the whole process stress free and easy!
Crystal Fajen
Sargent Auto & Diesel Repair got us in quickly for a second opinion. Not only did they work quickly on the repairs needed but kept us informed of everything! They were wonderful to work with! We will be back!
Jennifer Staats
A+ in every way. They treat you like family. Do what they say they will do and to top it off the final price was less than what they projected it would be!. I would highly recommended them to anyone looking for an honest fair shop!
Professional, courteous, and personal service. As a woman I try to educate myself on problems before I take it in so I am not blindsided. I have recommended this shop to anyone that asks. We are always on the same page.
