Always fair service.

Straight forward bids and fixes stuff when very seldomly it's not 100% the first time. I've taken trucks to George many times and he's always been fair! - Nate D. (5 star review on Google)

I don't trust any other shop!

I don’t trust taking my truck anywhere else! This shop has taken care of me time and again. These guys have so much knowledge and skill. They provide the best work with the most integrity. - Nick M. (5 star review on Google)

Unbeatable prices.

Was in town working when my truck suddenly started leaking exhaust pretty bad, it was preventing turbo compression. Came in on a Friday morning with no appointment, notice or anything, and I was expecting to have to leave my truck at least through the weekend. I got a call a couple hours later...my truck was ready... not only that, the price was unbeatable!! - 5 star review on Google

Quality service!

George and his staff are first class. Very knowledgeable and quick to get you in and out. They deliver quality service at a good price. Highly recommend if you need a diesel mechanic in Cheyenne area. - Josh F. (5 star review on Google)

You can trust Mr. Diesel & Auto Repair!

If you have a diesel, this is the only place to go for service. They have worked on my 7.3L twice and both times have been top shelf. They are above all, honest and will not try to do more than is needed. What they do is also done right and complete. My truck has never run better and nobody will work on my truck but Mr. Diesel. To have a good diesel repair shop that you CAN trust is worth everything. - David W. (5 star review on Google)
