What Our Customers Are Saying
I was very impressed with my recent experience at RNB Auto Repair. The owner Joel was friendly and very knowledgeable about my car. He gave it a full tune up, replaced all fluids, and the cost was reasonable. He even went out of his way to to fix my passenger seat which was squeaking and driving me crazy. I could not recommend Joel more to others and will definitely be coming back for other maintenance needs.
