What Our Customers Are Saying

We have had Scott and Earl work on our cars for over 20 years. They helped us get 430K out of our Toyota Echo before the A/C failed and it just didn't make economical sense to repair. We know they will always give us an honest opinion on what needs to be done and charge a fair price. They are a pleasure to work with.

-Stephen S.

Scott, Eric and the gang are a good bunch to work with. Having worked in the industry myself for a number of years, I know when a shop doesn't have it's stuff together. They are honest and do a good job.....what more could you ask for?

-Craig K.

Trustworthy, kind, and fair. What else could you want or expect from your mechanic? We wouldn't take our cars anywhere else.

-Janine M.

Great service and I can trust them with my car. Highly recommended.

-Michael C.

Very pleased with the work that Twin Ridge Auto did on my wife's minivan. The communication was excellent and the speed of the service exceeded my expectations!
