Todd Witherspoon, 05/16/2026Excellent service, highly recommend. I recieved an honest assessment of repairs needed. Tjere was no pressure to address minor issues, that could be fixed later, and I recieved a modest and reasonable quote and pricing for work performed. Staff and mechanics really went out of their way to make sure all my service needs were met to get my vehicle back on the road. Everyone at the business treated me in a kind and courteous manner. I would highly recommend Superior Auto Clinic for any car or truck repairs as they service all makes and models!
