My peterbilt had a wheel seal leaking on a steer tire. Called Scott and he got me right in and done. Just saved me missing out on a load. Thanks for the fast and friendly service

We are from Missouri and planned to be traveling through Great Falls The following day and had the serpentine belt go bad on our Newmar RV… I called Mechanix Unlimited and they had me transferred to service department and spoke with Scott and he assisted me in determining what belt I needed and had it ordered and the next day had me just stop in put it on as we were coming through. The process was seamless. I pulled into the parking lot. They installed a new belt and I was on my way within an hour. People were very friendly, respectful and just absolutely fabulous to work with. Thank you to everyone at Mechanix Unlimited you are a pleasure to work with!!

Thanks to Scott for his due diligence to get my car in for repair. Nick, the mechanic, searched the leak until he found the problem and fixed it.

Enjoyed Fallyn at the front desk and Karen in the back office as both very pleasant to work with on paperwork.

So glad this company is in Great Falls. ★★★★★

Traveling in out RV, a slow dripping leak was detected on the pavement while touring Great Falls. Called Scott and he would try to get us seen on a Friday afternoon, even with an emergency repair ahead of us. Diego checked and tightened a lower radiator hose clamp then performed two pressure tests and both Diego and I were satisfied with the corrective action. Yes, the standard diagnosis fee ($150) was a bit pricey but we were very satisfied with the service from getting us in, doing the repair and getting us back on the road the same afternoon. Thanks to both Scott and Diego for helping us continue on to Alaska!

Great company!!! I needed a wiper motor replaced asap in order to deliver my load today a few hundred miles away. Scott made it happen and Diego did a quick and professional re and re and got me rolling!!! Thank you so much for great service. I had gone several hundred miles trying to find a shop that could fit my truck in, and they did it!!!

I was having some electrical issues with my '12 Chevy Traverse and had tried several fixes before bringing my vehicle to Mechanix Unlimited. Scott and his team were great and figured out the issue within hours and had it fixed up shortly! It turned out to be a fuse and Scott was very apologetic that I would have to pay labor for it to be just a fuse but I was just so appreciative that they had found the issue! He even worked to take some time off and honestly I'll return from now on with any issues I have!

Alain Gyger

Highly recommended mechanic. They do quality work and don’t overcharge for it. They don’t mind talking through issues and answering questions, which I really appreciate. They are booked out quite often, but they’ll fit you in soon enough. They always call the day before to remind you about your appointment.

I needed some repairs on my pickup and they were able to fix it.

Jim Hillenmayer

Tried numerous rv repair places to fix our dash vent system but they all wanted me to leave our rig with them for an unknown amount of time. Since it's our home that was a non-starter. John at MU the only one who agreed to have someone look at it on the spot. True to his word, when we showed up he immediately assigned a tech to our rig who was able to at least get air flowing. Charged me a VERY reasonable rate. Couldn't have been happier.

We were in the middle of a cross country RV trip with kids and a dog, when the check engine light came on. They were able to squeeze us into their busy schedule, and fixed only what needed to be done, at a very fair price! Thankful for the kindness from the owner and ability to get back on the road quickly!
