They repaired my truck in one day. I broke down in Cheyenne and called them before close and they took one day as they told me they wood. Very knowledgeable, very helpful, and they give military discount. They explained all the work they did and had shown me all the parts that were removed and why they were replaced, because I asked. Should have taken two days but because I was in transit he had two mechanic working it to get it done and get me back on my way. I recommend them whole heartedly. Very honest and down to earth. The owner is really easy to work with.

I will be back and send all my buddies to mr.diesel!! Good people, very helpful! Would recommend theses guys to anyone serious about their truck

Stopped in last minute while they had several other projects going. They were quick to help diagnose and fix the problem and get us back on the road. I highly recommend them for their quick, friendly, effective and efficient work!!!

First experience customer service was ok. Not the worst but not amongst the best I've seen. 2nd encounter I spoke with George who was a lot better in customer service then the previous time. Last minute shinanigns but they pulled through for me. Of course I had to be there on time but they could of said no and I would of been SOL b/c they are closed on the weekends. I give 4 stars due to customer service.

I brought my car here for a broken timing belt. They had it up and running very quickly! Very professional and great customer service! I will go back if I ever need anything else done! Great price on labor too! A+++++!

A BIG THANK YOU to the guys at Mr. Diesel in Cheyenne, WY for gettin' my truck back on the road!!! Also, they got on it immediately after towed in!! All VERY courteous!!

No problem with these guys. they did a complete top end on my 06 duramax, exhaust, cold air and tuner...I roll down the highway at 75mph and get 25 to 28 mpg. Some folks need to lighten up. Especially the ones that don't know what they are talking about.

I am from Phoenix Az. I called with a problem with my Rv. They usually do not service RVs but made an exception for my situation. They are very courteous and quickly troubleshot and repaired my Chevy 454 engine problems all in about half a day. Thank you for saving our vacation.
