Engine replacement
I had an excellent experience with the team at Route 66 Automotive. They handled a highly complex engine replacement on my Land Rover with exceptional professionalism and expertise. From sourcing … More the engine to installation and final delivery, the entire process was seamless—and the vehicle now runs like new. I’d especially like to thank Isaac and John for their attention to detail and consistent communication throughout the process. Their updates and transparency were greatly appreciated. I’m also grateful to the entire team for their support and commitment to quality work. Highly recommend Route 66 Automotive for anyone needing reliable and skilled service! Less

Definitely my go to mechanic. They have helped me out greatly both times and done so in a timely manner as well as saving me money all the while. Isaac is always super helpful and knowledgeable … More even when he doesn’t know the answer he is thorough in getting it. I recommend them to everyone I know and once again I give them 2 thumbs up!

Great Interaction
My name is Percy, and I had my vehicle serviced at Route 66 in Fontana on April 2, 2026. My initial point of contact, Issac, was professional, knowledgeable, and fast. He communicated all … More pertinent info to me and he got my vehicle squared away. From a financial aspect, the company really worked with me to make it as easy as possible. My overall experience with Route 66 has been very positive. Less
