I would not entrust repair or maintenance to anyone other than Duval’s. I have a 2016 mini cooper. Footwell module repair and service, at a reasonable price. Excellent diagnostic, repair, communication. Thank you!

Fair and trustworthy! My daughter had her air conditioning serviced. As a concerned dad living in Michigan, I was worried that she might be taken advantage of. They told her to have me give them a call. They walked through the issues and treated her very fairly and with concern. They handled the unexpected problems very reasonably. This is a great family-owned business. Thank You!

I truly appreciate the services at Duval’s. They are honest and trustworthy with their estimates and job completions. The team and the front office, has great communication with the excellent team in the back! I am never out of the loop of what is happening with my vehicles. I trust them with all 3 of my vehicles - 93 Land Cruiser, 2012 Dodge Ram & 2020 Mercedes Benz

Eric and his team are fantastic. I had an engine overheat and had significant damage. They helped diagnose and were patient while I found a specialty mechanic to rebuild in my older BMW.
