Per a reference from a colleague and being unfamiliar with Ann Arbor, I stopped in to check out Advanced on a Monday afternoon after work. Cameron was receptive and helpful, diagnosing a check engine issue with clarity and recommending proper service. Later in the week I stopped in to have the issue fixed and the service was prompt and concise. I was very pleased with his candor and sincerity and will definitely consider AA again for maintenance and any repairs my car may need. Thanks, AA!!!
