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

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)

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)

George took care of me while passing through from Saint Louis, had a minor mishap and he took time to get me back on the road within 20 minutes, he saved the day! Highly recommended!!
