I normally don't do reviews. However I have to share my experience with One Stop Auto Service…read morelocated in Brentwood, California.  I had the absolute best customer service ever.  I had a family emergency on a Friday evening prior to a holiday weekend.  I called several shops and Noone was able to help me until Monday.  I was about to give up but I made one more last call and it was to One Stop Auto Service. After explaining my situation with what my vehicle was doing they seemed very happy to help me. They squeezed me in at the very end of the day, diagnosed my car and I authorized the work and shortly was on the road to my family.  The mechanic was very knowledgeable and explained in full detail so that I understood. Ashley, the office administrator was my 1st contact when I called and she made me feel important and was eager to help. The service from my 1st call to the office and then mechanic of my car was 110% Above and beyond my expectations.  I recommend them over any other shop. Call them and you will see, you will end up making them your One Stop Only Shop Go To Mechanic knowing you are receiving the most excellent top knotch service and skills from a highly experienced mechanic.

I called a couple local places, and One Stop quoted me the best price, and charged by the pound on freon when other places in town charged a flat rate of TRIPLE what I paid at one stop. We arrived, and talked to Chad and I went in to do Paperwork as Chad harmlessly flirted with my fiance (I understand Chad Shes GORGEOUS) We headed next door to an Air Conditioned Mexican food place, came back and the car was done. Chad told me, that JUST IN CASE there was a leak, he put some dye in the system! Went to go pay and I dont know how it came up, but the nice lady inside alluded to having some native artifacts.... I checked them out but didnt get any... All in all... Great experience! Glad we found them! Would recommend! Also.... a HUGE THANK YOU!!!!!!

I recommend this place highly professional, very honest business.

I couldn't get 3 different smog shops to just plug in their computer so I can get a VIN number verified by the bureau of automotive repair. However at O'Brien's without hesitation, he was able to get my Vin for me and did not even charge me I really appreciate how easy going and understanding he was definitely going to bring my other vehicles back. It's hard to find help like this nowadays. Thanks again!

He was on time and about the same price as a shop to complete the job, but the convenience of being at home and not waiting in a shop made him more appealing. While he had the wheels off we discussed installing the shocks and struts for my truck. There were full size struts in the front and shocks in the rear. I made an appointment 2 weeks later to install the struts and shocks. David came to my house but did not have a compression spring to install the struts. He said he was going to get some tools and come back. I said ok no problem. He never showed back up at my house. I had to work that afternoon and his assistant said they would come to my job and do them. They had to go pick up the compressor needed and would be at my job. 2 hours later they never showed up. I texted saying that Its safe to assume you are not coming back out tonight. The next day I got a text message apologizing for the mix up and they wanted to do the job. I said Ok Im at work but have money on me its not a problem. My truck is just sitting there. I told them exactly where I was located and they said they were there. I went outside and nobody was there. I texted and call several times but had no response. i finally get a response saying that we were there but you weren't so we left. If the job was too big for David to do I wish he would have been honest up front and said that he could not complete the job. If he didn't want to do the job he could have said that as well. Instead I felt like I was dragged around when I could have found someone else to do the job. So no I won't recommend him for anything other than a simple brake service, and even then I might shop around for a cheaper price.
