My scheduled service to replace tire and 5,000 mile
My scheduled service to replace tire and 5,000 mile service was in and out in great time for what had to be done. Service advisors had great customer service and made sure you were happy with everything done. I have loved the buying experience from this location as well as the people. My service agent, Harouna Fofana, was top notch! 10/10
