They are not BBB accredited! They do not abide by their warranties/ contracts! They are sketchy! I was recommended to P&G from sals auto mechanic in fontana, I have a toyota celica Gt 01 that had sucked up water into the intake. I needed a new engine. Sal had told me that this was the place to go. Alex, the owner had quoted me a fair price to install a new 1zz motor (the same kind my car comes with originally) he also said he could switch the position of my intake so that it wouldn't suck up water again.(He didn't) The job was to take 7 days and cost me $2200 with a 1 year or 12,000 mile warranty on all parts and labor. However, upon initial payment of $1100 and 12 days later. I called Alex and he said I needed a new air control valve because the car wouldn't idle right, he also said he needed to install a new "knock sensor", something I've never heard of before. It would cost me an additional $250 and another day of work, I said okay. I just wanted my car fixed. Finally after about 12 days and after I paid the $1450 I got my car back, I understand that cars with new engines have a "break in" period of 3 or 4 months for it be in top condition; so I made sure to drive with caution and made sure not to accelerate over 3000 rpms in between gears. After 1 month, my check engine light came on and my temp was spiking. I took it back to Alex and he said I needed a new temp coolant sensor. I paid $125 for the part and he installed the part. The problem did not go away. Not even a day later the light came back on and he said it was suppose to be a different sensor. He told me he charge me for this new mystery sensor, but after he installed it the problem seemed to be gone. I drove my car for 2 months before I got an oil leak. I took it back and Alex told me it would cost $600 for a new head gasket and seals, he also said that he would not cover it under the warranty because it was because of overheating due to the temperature coolant sensor, the same one that he installed 2 months before! Be warned! This company is not BBB accredited! They are sketchy! And they do not abide by their warranties/ contracts!

1 year ago my brother-in-law referred me to Midas Diamond Bar after I told him I felt the Toyota dealer I had been going for 3 years up-sold some unnecessary services to me. Since then this place has been my go-to shop for all my car maintenance and repair. The staff (Nitin) was really nice and very honest. Doesn't try to push some unnecessary services to you. They make sure that they take care of you nice and fairly and that you feel comfortable with them so you will come back. And I will def come back. -Jared Wu

Got a flat and got it towed here because it was close to Cal Poly. People here are really nice and they fixed my tire for free! Brian was really cool and we had a friendly conversation while Mynor was fixing my tire very quickly. Probably the best experience I had at a car service location. Highly recommend! Jose Jimenez

Always warm and friendly, excellent service. Like the new outside seating area, for waiting if necessary.

Absolute best experience I've ever had at an auto shop.Terry was extremely friendly and most importantly: honest. I will take any business I have in the future to his shop.I recommend it a thousand times. Whether you're 5 miles, 20 miles or 50 miles away I suggest you take the trip and get your car serviced here.

LOVE Nobert's Auto Service! Nolbert himself owns and runs the place! VERY VERY....did I say VERY HONEST! GREAT friendly service....They get the job done right......The price is so fair.....and DID I say HONEST? LOL Highly recommend! I drive almost an hour to have my car serviced here! Been going for years and a lot of my family and friends now go too!

I have been doing business with ABD and everytime it is a pleasure to know that my car is always well taken care of. Adrian is very knowledgable when it comes to parts and cars. He goes above and beyond for his customers. Thanks again guys great work.

We used to have a family friend fix all of our vehicles but when he moved out of state his brother didn't do much for us. So we started to see Paul at American Tire Depot on Magnolia and he and his team really took great care of our vehicles. Thankfully Paul just recently came back here and I don't think I would ever take a car anywhere else. Chris Zmolek

I arrived and asked if they could SMOG my truck and it was done quickly and efficiently. Going to bring it back to have it serviced on a regular basis. James Pinmental

RIP OFF! These guys repair cars like junk. Stay away from this them. They miss numerous bolts and my engine was falling off. Even the battery was not bolted on. They break things as they are going through and do a horrible job. Rather than taking care of the Engine light problem they simply just reset it and I drove off with the engine light still on. If you love your car, go somewhere else.
