It’s 4:00pm on a Friday night and we are traveling in our RV thru Ontario Or … the check engine light is on… John ran a diagnostic test and determined it was a battery problem. He made a call, had a new battery delivered and installed it now after hours!! He is a thorough and great guy and a great mechanic!! Thank u john for saving our trip!!
Great clutch repair on my ram truck. Excellent, very knowledgeable mechanicsJohn's is a very busy repair shop, but the wait is worth it. John gave me a verbal quote and final bill was real close. No B.S. just honest, quality work.
