Diamond Bar Auto Care

Excellent customer service and very reasonable pricing. They are there to help and not rob you like other repair shops and dealerships

Im a customer and so are my kids. We’re always grateful for the thorough and trustworthy service we receive from Harry and his crew. They go above and beyond always exceeding my expectations.

Everything was done that needed to be done, Did a great job on my car

They to very good work and let you know of any problems that may occur during your auto service

Always great service. Friendly, knowledgeable and honest.

Great work.

I would be lost (and quite literally) and stranded without this place. Harry & Harry Jr are great -- all of the mechanics here genuinely care about their customers and the work they do. They take their time to explain what's going on and in a way that makes sense to people like me; cars & parts to me are complete rocket science. I never want to go anywhere else!

As always Honest 1 Auto took care of my vehicle for me in an expedited manner. Everyone is always friendly to me and my children when we need to stop by for routine oil changes or other vehicle maintenance. I appreciate the hospitality and would continue in the future to give them my business. Thanks again to Harry Sr., Jr and Jommy who gave me a ride home this last time around. Keep up the outstanding service.

Very respectful staff, actually went out of their way to point out that my splash guard was broken and down and brought me back to show me how he could try to fix it himself. I offered to pay him extra and he insisted he couldn’t charge me and asked for a very reasonable price for an oil change. Also went out of his way to explain my oil filter and how it works. Had a great visit would absolutely come here again.

Best mechanics I know.
