What Our Customers Are Saying

Excellent service, professional and friendly staff. Knowledgeable techs and gear guys. Respectful and thorough. Thanks for getting our vehicle back on track!

-Kip & Joan

The staff at Jeffrey Auto Repair were very professional and explained what repairs my auto needed. I would recommend them to anyone. The building and grounds are very clean and neat. They know how to treat their customers.

-Dolores K.

I would highly recommend you guys. You were courteous throughout the six weeks you had the vehicle. You made a ton of repairs including the transmission and radiator. But that is not all. I felt as though I had an honest advocate working for me that thought as much of my vehicle as I did. I continued to get options on things that SHOULD be done to keep it running good and things that WILL need fixing in the future. You did not suggest I do everything and that shows your honesty. I feel very confident in the repairs. You even tried a less expensive solution to fix the transmission. Thank you. In the end, I needed the transmission, though, and you had options for me. But all along the way you explained what was wrong and gave me options when there were some. You even went above and beyond and cleaned up the Suburban before I picked it up. I can honestly say no one else has repaired my cars since moving to Mason City 9 years ago. In fact you fixe! d my F-150 when the Ford dealer was unable to do so for 2 years! I have no need to find anyone else to work on my cars. Feel free to share this with any customer. You can even use me for a reference.


It was great to have the charges actually be around $30 less than the estimate. Very pleased with all the work you have done for us on each vehicle we have owned over the years.

-Melvin A.

I called at the last minute and made changes to the work I wanted completed on the vehicle. Brian and his mechanics were very accommodating and completed the work before the time the vehicle was promised. I always feel completely comfortable leaving our vehicles for service because I am confident the work will be completed professionally and correctly. Jeffrey's services our vehicles like they are their own. Thank you.

-Linda M.

We've been going to Brian (Jeffrey Repair Service) since we moved into the area in 2012. We found him on accident, but have come to realize that we are extremely lucky in that!! Since then, we have had 5 different cars and he (and his staff) have been amazing on the work with each one of them!!
