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!

This shop is fantastic. Jim delivers old school customer service with a great job at a fair price. I've had two of my trucks in there and was impressed both times with both the service and results. Shops like this are far and few between these days.

Daniel Neil

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.

Ben Zo

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.

Rod Timmer

Great place!! Jim and Dave done me right. Definitely worth the trip

Roger Meadows

One of the best shops we’ve had the pleasure of doing business with. Jim set up the alignment on our new Cascadia 2 years ago. Best tire wear I’ve ever gotten out of a set of steers. (245,000 and they had a few thousand miles left in them!) Just had it in to set up for the new set. Couldn’t be happier. Nice, clean shop. Got right to work and kept us up to date. Awesome!

Jim Back

Had Jim's crew do a 3 axle alignment turns out we had a really bad steer tire so they got us fixed up. We couldn't be happier. Thank you for everything, we will be back.
