Richie and his crew always does a great job on my car and at a reasonable rate.

Best shop. The guys have been fixing my car, my parents car,and my grandparents car for over 15 years and their still the best.I would definitely recommend this repair shop. I send all my friends to this shop and they also love the guys.Very honest mechanics.

Honest mechanics that tell you what’s really going on with your car and who always get the job done right! Always go here and will continue to always go here!! Lawrence Taylor

Dave and his staff at Diamond Auto do exemplary work, honest and done right the first time...always. Never an issue and always on time and often under estimate, I couldn't ask for a more professional and skilled shop. In a world where it is often lacking, Diamond Auto has integrity.
