Diamond Bar Auto Care

A mechanic who is competent, honest and fair is one of modern life's blessings! And right here in Diamond Bar, too!

I came in with my commuter car that my wife was worried about suspension wise, I was greeted by Harry JR. And Jimmy inspected my vehicle, both men were straight shooters and even told me that there was no real need for any large repair as the car was older and had almost 200K mi on it, and didn’t charge me a thing. The fact they didn’t try to sell me on anything and kept things straight I truly appreciate! I will be coming back here in the future for sure!

It was not honest something that could be fix so simple I got charged $49.99 and they told me I did not pass smog. I should get back my money I am disable I don't have that much money. Thank you.

Great customer service. Serviced our mini for a fraction of what the dealer charged. Informed us that there was one service recommended by the dealer that was not necessary. Thank you for your honesty. We found our new mechanics for all of our vehicles.

Excellent service and friendly staff I appreciate. My car running great 👍 Thank you so much. Lana hue.

The name says it all... I am a certified mechanic, however every now and then I don't have the time to work on family vehicles so I Honest-1 Auto Care do the repairs. They are very fair with the prices and great quality work.
