Honest, fair & efficient...

"I have been using Poston Motor Co. as my repair shop on all of my trucks and SUV's for the past 5+ years. Matt always gives me a direct call and let's me know exactly what is going on and how they are going to tackle it. Matt is also a no BS kind of guy and straight to the point. Honest as well, which is something you don't find nowadays. Their labor is solid, prices are fair, and they are very efficient in getting the job done. I would not waste my time going anywhere else in the state to get my vehicles worked on. Big thanks to Matt and the Poston team for their continued efforts and hard work!"
