Its not glorified auto service center. No wiating roon withbfancy tv or ac. Its a poor man's auto center. How amazing though. The prices are honest. No crazy labor cost like when you go to service centers. Will keep on going back. read more

I have been here to do the maintenance for three times, Uncle Zhao has done a really good job on my car, he lets me know about my car on some useful aspects, and tells me when to come for next time. Besides, he also tells me how to check the situation of my car, trust him! read more

I used to get a small accident and need to do the spray painting for my rear door of passenger side. I found this body shop because of my friend's reference. I didn't expect they would get the job done that fast until I got my car back within 2 days. The price is pretty fair and their service is a big plus too. The owner of this shop would deliberately and patiently explain all car stuff to you and give you professional suggestions. I absolutely will go back to this body shop if have another car issues. read more

See all

So, my car wasn't starting and I had it towed here because the driver of the tow truck recommended it. It also happens to be one of the very few auto repair shops open all day on Saturdays and Sundays. The owner "Simon" was absolutely amazing. He was funny and friendly and his customer service could not possibly be better. I ended up just needing a new battery and a couple belts, but he went above and beyond to make my car in tip top condition. He checked everything and made sure to show me what he was checking and finding out every step of the way. He also changed my air filter (it was ten years old), filled up my tires, tightened other belts, and put his all into my car. I didn't know a mechanic could be so honest with such reasonable prices. I will definitely be sure to not only return here, but never go anywhere else. :-) read more

The owner of this shop is SIMON!! He's the most honest n trustworthy mechanic I've ever meet. He's also funny along with GREAT customer service.. I come here for everything!! I have an 08 Infiniti G35 and he takes care of my car like if it's hi very own! He also open late everyday including weekends. I stop going everywhere after I found this, not because he's funny or because he opens late.. But his price is also unbeatable!! read more

I've been recommended by my friends to come here to do maintenance, Mr. Zhao is very friendly and professional, he did a great job on my car, he detected some small problem of my car, and he suggested me how often should I send my car to do maintenance. I will definitely send my car to do maintenance or troubleshooting later. Great auto body shop!!!! read more

I brought them a 97 Toyota Camry that a private seller was selling. I didn't catch his name but the manager of the place personally inspected the car that I brought him since Upstar Auto Sales and Services said that they didn't do "mechanical inspections" which is kind of strange considering that all the Yelp reviewers say that they are such a great place to bring your car for maintenance and repair. You would think that they do mechanical inspections but I guess not. So...I had to find an alternative auto body shop and I saw D.S. International Auto Repair right across the street and I thought, why not? I called them up, told them if they do mechanical inspections and they said that they did, so I told them I'll be there in like 5 seconds. Five seconds later, i was there. I get there and told the first guy I saw if he was the owner. He corrected me and said he was the manager. Then I told him that I was the one who called like 5 seconds ago and, he was like, "Ok, so where's the car?" He popped the hood, looked inside for a mere 2-3 seconds and told me that it has been in an accident--most likely a frontal one. He told me that the color of the hood and the inside brackets were different colors. The stickers that were missing indicated this to be the case. Ordinarily, he said, there would be these stickers that are inside a car that shows that it came from the original manufacturer. Those were missing and by California law, he said, they MUST be pasted on the car on the inside of the hood somewhere--unless you're a private seller, in which case, you're simply ignorant of the law. Then he peered over the engine block and told me that there was a massive leak of oil on the surface (he points it out me and shows me the the leak and where it came from) and that means that there must be a massive leak underneath the engine block. Very bad, according to him. He said ordinarily, Camry's RARELY leak oil, if ever, assuming you took care of it doing all the regular maintenance that it needs. He then took it for a test drive and told me to come along. He told me during the drive that the shifting is hard and that most likely the transmission is not the original Toyota Camry transmission. Usually, the shifting is smooth and kicks up or down relatively fast between the 1st, 2nd, and 3rd gear. Then he told me as he was braking that the rear two brake rotors are probably shot or warped because there was shaking when one presses on the brake. That's not normal, according to his diagnosis. He told me that the transmission is not good, meaning within a month or so, it'll most likely breakdown since it wasn't made to fit and for use in a Camry. And then he was like, "it'll probably cost you $1,400 to fix it." I was like, "Good to know..." All throughout, he was very detailed in his explanation. He broke it all down in layman terms and in a way that I can understand him. At the same, he didn't sound condescending at all. He spoke to me as if he knew a lot about Toyotas and it seemed like he knew a lot as well. Nothing in his expression or "aura" that he gave off seemed like he was lying to me. He got straight to the point with no bullshit. AND! He didn't try to sell me anything that I didn't need. I greatly appreciated all of that. After the whole thing, he ONLY charged me a mere $25 for all that. Wow! What a bargain! Man, aside from Chia-In Auto Repair on Garvey Ave who charged me $20 for the whole mechanical inspection on the lift, this is the next time cheapest auto repair shop I've ever been to and plus, he was just as honest as Chia-In Auto Repair, if not more. I highly, HIGHLY, recommend this place if you're looking for relatively cheap, honest, and quick service. read more

Mr. ZHAO is very professional and provided great service with reasonable price! Will definitely recommend his service to my friends.

I've been coming to Simon for the longest of time! He's very helpful, knowledgable and honest. One of our family friend recommended us to him and I was a bit hesitant but he was very funny and has made me feel comfortable. Several years back, I bought an used car, 96' Honda Accord, from Simon and I hardly have to take it in but it didn't last me long due to my drifting but after the end of my first car, I got my cousin's 00' Volkswagen Passat Turbo, I went in for a check up and smog test. The prices here are affordable and he takes good care of my babies :) Whenever there's a problem, I come to him to fix up my cars, anyways.. in the end, I gave up on my white marshmallow (Passat) due to the transmission failure. Since then, I got my baby last year, 10' Honda CV-R. Obviously no problem with my import but you know who I'll go to if there was, besides the dealership.. it'll be Simon. read more

I found Simon (D&S) through Yelp when I was out of town and our van broke down on the 60 fwy. He helped us find a tow company and fixed the van within an hour. Thanks for a great experience...when things could have gone worse! read more

This is the first time I wrote a review on the Yelp because I really think I must to. This is an old shop with a new boss. I bring my lexus to here to do the maintenance. Zhao Gave me a very good deal and the best engine oil. He did it very quick and he is a very kind person. My brake was almost run out, Zhao gave me a good price and let me consider about changing it in his shop. when I got back home, I checked the internet, I found his deal was good and I trust his skill. I think I will go there change it soon. By the way, I love his logo on the namecard read more
