Really great service. I came in with a engine debate problem and they stayed late to get it fixed. Tanner explained everything and didn't make me feel slow. He talked and he also listened. I really wish more mechanics in this industry did that. The prices were not crazy. Real people doing a real job and treating others like real people. I'll definitely be back for service when I'm in the area.
Great place! Pricing, communication and service all excellent
They sell quality parts at great prices. Would highly recommend them.
Top notch!! These are great people to do business with. Reliable and on time. I'll be a repeat customer. Thanks
Went to the dealership, they wanted a mortgage on the part, started shopping online was skeptical. Pull the trigger on the actuator and had to dealership put the part on and calibrate it. Smiling from ear to ear
Fantastic! Had a brake chamber bust loose mid afternoon on a Saturday and was assuming it would be LATE getting it fixed, if not having to wait til Monday. These guys gave my breakdown desk a pretty exact ETA, then also called me directly when they started my way, and showed up exactly when they said. Quick diagnosis, then they picked up the new can and met me back at their new, easy, convenient yard. Quick work, very reasonable, great guys to talk with. They are eager, knowledgable, and seem to be very focused on good, honest service. The shop we all wish we could find when we're no where near the house!
