Certified Performance is an independent, privately owned auto repair shop and an official NAPA Auto Care Center. As a NAPA Auto Care Center we give you a nationwide 24-month/24,000 mile guarantee on all work we perform. That includes parts and labor. 

At Certified Performance, we work to provide you with personal service. We consider you a valued customer---not just another number in our database and we want you to be pleased with our work so that you will come back again and recommend us to your friends and family.

When we perform any repair on your vehicle, we give your car a complete inspection (front-to-back, top-to-bottom) to check for potential problems, to prioritize repairs and to provide an estimated cost for our services.

All Certified Performance mechanics are A.S.E. certified.  (The National Institute for Automotive Service Excellence in Leesburg, Virginia administers testing and requires hands-on automotive experience before issuing certifications.)


We devote 60 hours a year to continuing education to keep up with the latest in automotive technology.

What is the ASE Blue Seal?



The ASE Blue Seal stands for the Institute for Automotive Service Excellence.

Our Customers Are Kind Enough to Share …

"For everyone at Certified,
I just wanted to take this opportunity to let you know how much I appreciate you for the honest, fair and reliable service you provide. When my husband Brad and I moved to Troy from St. John one of our biggest concerns was that we wouldn’t be able to find anyone that would even come close in comparison to the trustworthy service you all provide. I am sure you can imagine how excited we were to receive notice that you were moving to Moscow Mills! It was like our prayers were answered and they have been.

You should all be very proud of the quality work and excellent service you provide as well as the fact that your customers are receiving trustworthy & reliable care. These are all very rare traits nowadays and I never hesitate to promote you to anyone looking for a mechanic they can trust. You guys are the best and you can bet that we will be customers for as long as you’ll have us.

Keep up the good work guys (and gals)!!!!"
Debby & Brad Koehler
