Testimonials
Rex is awesome!!! I needed a safety inspection on my motor home and they were fully booked. Rex told me to come in before they opened and he did it then for me! He was very thorough and great to work with! Best costumer service I’ve had from a diesel shop anywhere! He is a hero and saved our vacation!

Just had my car finished by James and I must say it was the best service I have ever had. I was filled with confidence when I drove my car for the first time. After all the service it had It was running so much better than when I first got it used. He explained to me what needed to be done, in a way I could understand, and was right on the money on his diagnosis. I could not be happier and will definitely take my services back to him on all my autos and RV. I highly recommend if you need service, James makes the difference
