Diamond Bar Auto Care

Great customers service.

Great service, honest and caring

Honest work, great and fast service, ask for Joseph or Alex..

They have reasonable pricing...saved me almost $200 on my F250 transmission fluid change + 4x4 differential and crankcase service, and they are honest! When I picked it up, Henry informed me that my cost was LOWER than the estimate because my truck only had one filter instead of two. Apparently, the early 2008 models used two and the later ones only one. Last time I took my wife's Lexus in for a problem, I asked them to check the brakes, since she had over 100k miles. He told me they looked good, still had about 25%! Most places would recommend changing them, don't find that too often.

Always honest! Always fair!

Harry Sr and Jr are 2 people anyone can trust for their cars

Harry and Junior were attentive, knowledgeable and genuine. The work was completed in a timely fashion.

They do quality work at a reasonable price and don't try to upsell you for stuff you don't need.

I have been coming here for years and it’s GREAT! Good service, and good people you can trust!

I highly recommend Honest 1 Auto Care, Diamond Bar. I have been having my vehicle serviced here for quite some time. The work is done efficiently and my vehicle is ready within the estimated time. The employees are always pleasant and helpful. The waiting area is always clean which is a blessing when you are waiting for your vehicle. Something you don't usually find in most auto repair facilities.
