JM Diesel 1730 County Road 322, Liberty Hill, TX 78642

"Had severe electrical issues, and Jonathan found a chewed up wiring harness. Got it replaced and back working great. Communicative, polite, and great work for the cost. I'm actually referring a friend to him tomorrow."

"Had A/C issues as well as some electrical issues on my 2008 Dodge 2500. Took it to Christian Brothers to get diagnosed and they quoted me roughly $4,500. Gave me a diagnostic list a mile long. A friend told me about JM Diesel so I took my truck to John. John’s price for repairs was a quarter the cost of what Christian Brothers quoted me. John fixed all the issues on my truck and it runs like new. He’s kind, professional and honest. I’ll never go anywhere else. Thanks John for you hard work and integrity."

"This is the BEST diesel and auto mechanic in central Texas!! One of the things that you won't need to worry about is being ripped off. Trust me, I've been there many times and Mr. Jonathan will always give you a fair price and his work is very HONEST. Highly recommend this place if you love your vehicle and want it to be well taken care of."

"I brought my truck to this shop after a different shop couldn't figure out the problem with my truck. I'm glad I did. The mechanic did an awesome job on my truck and the check engine light is still off. I will tell all of my friends to bring it here. He really does a great job and is super nice to deal with. A+ work done. Couldn't be happier."

"Really great people to work with. Family owned. Jonathan knows what he is doing. Easy to talk to and most helpful. All my questions were answered. He is my first choice in mechanics."
