Steve was so kind & helpful! He didn’t have the tires we needed, but went out of his way to call around & find a shop that would be able to help us. Just an all around good guy, 10/10 recommend!!

I can't express enough how thankful we are for Steven Iler's incredible service. Last night, when every other shop was closing, he didn't hesitate to meet my girlfriend at 6 PM at his shop to address a loose plastic part on our vehicle. Being stranded with our baby was a huge worry, but he quickly diagnosed and fixed the problem, getting us safely back on our way in no time. His willingness to help in this way was truly exceptional and deeply appreciated. I highly recommend for any mechanic services you need.

We were forced to stop in Moriarty, NM due to DPF/SCR Codes and were lucky enough to have stopped in the right town. Steve really does have a PHD in this. We're grateful that he was recommended to us from a local mechanic shop in town. Steve is very insightful, informative, and most importantly honest. Helped us out with our SCR issue and got us back on the road the same day. He really does care about you and your business and does everything in his power to help. We run across 40 often and glad we now have Steve's number. Can't imagine sending my truck anywhere else if I have ever issues again. Thanks Steve!
