I took my ‘04 F-250 diesel to J & M. I could not be more satisfied with the work. Mike and his team fully restored my aging diesel and completely fixed my sloppy steering issue.

I had my f350 towed in because it wouldn't start. Mike had it fixed in two days for less than expected. The whole crew was pleasant to work with. Good honest diesel mechanic. Thank you

The crew at J & M took my 2000 F350 7.3 and got the front end back to it's original state, it goes down the road like new! They also fixed a bunch of little issues I had neglected for years, and I couldn't be more pleased. These guys know the business, with 250,000 miles on my truck I am glad to have them available to keep me on the road.

I called to have some work done on my truck. The first lady I talked to was very rude. Then I got handed off to another guy also very rude. They quoted me 20 grand for a tune up and changed my bed on the truck. DO NOT GO HERE
