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.
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!!!
Excellent work! Reasonable prices. Great guys to deal with. Dog friendly facility.
Great place!! Jim and Dave done me right. Definitely worth the trip
Jim does great work with only quality parts and out standing detail to each job on hand.
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!
