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!
10/10 recommend, very pleased, had doctor pre load done on truck and trailer and can’t believe the difference it makes. Alignment was also superb. Thanks Jim!
Great place to get your alignment, suspension work and other services he provides. Honest knowledgeable, and all around nice guy!
I just wanted to say thank you to Jim Fowler and his crew for a job well done. Their Attention to detail not only on my truck but his customer service reached new heights for me! Quality service at a reasonable price is very very hard to find these days. It's worth the trip from anywhere in the USA! Thanks again, Jim!
Jim has a vast wealth of knowledge about trucks and pays great attention to detail. I would 100% recommend him to anybody looking for high quality work at a fair price
Thanks Jim for making my truck go straight. I highly recommend your shop.
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.
