Prompt, friendly service! They checked for what I thought was a problem, and verified that all is good, and my car was safe to drive. It was one of those opportunities for a shop to sell you parts and services you don't really need, but they don't do that here. That's why I continue to go to Big O for my automotive maintenance needs. But when I do need something done, they explain clearly what and why. They've earned my trust, and should have yours, too!
