It is wonderful to find mechanics who care! I got a flat tire near their shop. One of the mechanics drove by and saw me sitting on the side of the road. He went back to the shop, grabbed a floor Jack and tools and came back and changed my tire very quickly. His kindness was greatly appreciated. This service was provided with the full knowledge and approval of the owner. If this is the service they provide for a passerby, then I'm certainly going to use them for my future oil changes and auto maintenance.

Robert is knowledgeable, efficient, considerate, and a heck of a nice guy. He answered our distress call immediately. His mechanic, Matthew, did excellent work. It is such a relief to find such outstanding competence “close” to home. Robert is a rare individual who understands the P32 GM chassis on our 2000 motorhome. We highly recommend you contact Robert if you need work on autos or gas engine RVs.

And “Steffen” is very knowledgeable about P-32 Chevy chassis also. They use only best quality replacement parts and charge a very reasonable price.

Great repair shop , very knowlegeable , diagnosis was spot on the tune-Up while a little pricey, was worth it got my truck running great , diagnosis on the Pulse Vacuum Hub (PVH) Solenoid was spot on. Highly recomend would use again if i could afford it LOL just kidding. !
