I took my GMC truck in to Rich to try and diagnose an inspection code issue. He was honest about the process, fully explained his basic cost and found that a prior repair had failed to connect an 02 sensor. Once that was corrected, there were still a few issues with re-setting the ECM and it took several attempts and drive cycles to get the codes re-set. Rich was patient and took the time to check the check engine codes multiple times. Each time, he provided guidance on what might be popping up due to misfires and a few other issues. After several drive cycles, Rich was able to perform a final test and the truck passed the inspection. I am very pleased with Rich and his team a Machado's and highly recommend his service. Having experienced bad service in the past, I can say that my experience with Rich was a pleasure and I will be taking my vehicles back to Machado's in the future.
