What They're Saying About Us
See why our customers consider Michigan MD Alignment the go-to throughout Coldwater and Allen, MI and the surrounding areas!
I’ve had Jim do alignments, adjust wheel bearings and install my oil bypass system. Always professional in his work. As being a former OTR driver Jim understands and respects our time constraints on the road.
Thanks Jim for making my truck go straight. I highly recommend your shop.
Very flexible and easy to work with. Great value as well. Owner is overly friendly so be prepared to be treated like a person. I bring them my whole fleet for work. Couldn't recommend them more.
We have had work done by Jim at Michigan MD Alignment multiple times on different equipment. Everything Jim does is top notch. Always taken care of the first time. Highly recommended!!!
There's a reason for all the 5 stars. I never felt I received my money's worth of an experience for a truck repair, not until I met Jim and his crew. The patience with my questions and time they took to get my work done and see that everything they could do to help me was done, was extraordinary customer service. Jim will treat you not as a customer but as a friend he hasn't seen in many years. I did a 3 axel alignment and they did a heck of a job I recommend this shop to all my friends I will never go to another shop if I can make it to Jim.
Great place!! Jim and Dave done me right. Definitely worth the trip
