Diamond Bar Auto Care

Took my 05 Ram in thinking my transmission was going out. Harry and team had it diagnosed in 1 1/2 hours. While I waited. Turned out to be a sensor causing misfire on a cylinder. Literally their name speaks volumes.

I've been going to Honest 1 for a while. Awesome people! Awesome service! I highly recommend them!

Love this place! I took my car to another service center in DB. The mechanics said I needed $2500 in repairs including new rear brakes. So, I went here for a second opinion. My brakes were just fine...nothing was wrong with my car. Thank you for your honesty. Thank you for saving me thousands of dollars and for not charging me for services that were not needed for my car. I appreciate your services. I will absolutely return for future car repairs.

Honest 1 was quick and timely. Thank you for valuing my time.

Can always count of Honest 1 for quick, reliable service. Thanks!

Great service great mechanics!

Everything was great

I brought my car in for a oil change on a Saturday. The office was clean , pleasant and there's even an area for kids to play in. The owner and employees were very courteous and responsive to questions and willing to go the extra mile for us. Everyone left the shop with a smile. The work was done quickly and efficiently. Definitely will come back.
