The knocking sounds were very quiet, and I honestly did not believe it would be possible to find the problem. But these guys were able to find it, and I am very happy. Thank you very much to them. It took longer than expected, but that is completely understandable for such a complicated diagnostic like mine.

It took me no more than one minute to see that they were way overcharging me for aftermarket parts. I then decided to call the dealer (most expensive parts you can buy) and in fact found out that I could get an original dealer part for less expensive than they were charging me for a cheap aftermarket part I encourage you to Google your estimate and see this for yourself before getting any work done here Another misleading thing was the manager up front seem to know absolutely nothing about cars or the automotive industry don't think that's a confidence builder to want to get my car repaired at a shop where the manager up front knows nothing about automotive repair. Do your own research and see I speak the truth

As soon as I pulled up to their garage this afternoon a whole team of people came to work on my vehicle. I was the only client there this morning. You could hear the technician calling out "right tire good" while someone else was checking my lights. It's such a breeze to get through here and the cost is affordable, For an oil change on standard Toyota Corolla was about $108. They also reset my dash to make sure my maintenance light was off. This will always be my go to for future oil changes!

One of the employees explained that I could simply drive through and remain in my car, so I didn't have to do anything besides sit inside while they changed my oil. They did ask me several questions about additional services, such as whether I needed new tires. I told them I only wanted an oil change. Just be aware that they may suggest other services, which can add to the total cost, so make sure you clearly state what you need. Fortunately, they offered a first-time customer discount, so I got a good deal on the oil change without adding anything else. Overall, I was satisfied with their service. The customer service was great, the employees were friendly and welcoming, and they greeted me and thanked me before I left.

One of the attendants got me started on the paperwork almost immediately. By 10:55am, my car was already being inspected, and by 11:05am, everything was done. The total, including the state paperwork, was $58--about $15 less than what I paid for my last smog check at another shop. I was really happy with the quick turnaround and the price. Highly recommended! BONUS MATERIAL: - They are a STAR certified station. Smog check was $49.75 (with coupon found on their website) + $8.25 for the CA paperwork.

When I went to the dealer, they quoted really high price and added a bunch of unnecessary services. I was able to get an estimate from Vuong which was much more affordable, and it was great to be able to text back and forth to make sure I'm only getting the services I really needed. It was also super easy to make an appointment. They were able to get me in and out in the same day even with all the difference things being done to my car. It was also really convenient that they have after hours dropoff available. You just park your car in their lot, and they have a safe place to drop off your keys. This was helpful because I had some work meetings I had to take in the morning at the time they opened, so I was able to go in before they opened and drop off my car. Highly recommend Vuong and his team if you're in need of any maintenance or repairs for your car!

I had to get new tires for my truck and so I went around to get a few different estimates. After…read moretalking with Erik, he was able to find me the best deal for my truck, which requires a larger size tire. During the process of swapping out the old tires for the new, 3 out of 4 of my wheels got chewed up a little. Erik called me down to take a look and offered me a few different options to make sure they corrected the mistake. The wheels I had on my truck were extremely nice (I liked them) but they were discontinued. So we tried to see if we could get someone to repair the scratches/gouges but unfortunately they would look the same. The would end up being painted completely black, losing that milled look. After a couple weeks I called Erik back and suggested we have to go another route, which would be for them to purchase new wheels for me. And so he did. (Not the same, but some very nice ones). They took care of replacing my old wheels with the new ones and everything looked ok. A day or 2 later Erik called me because he noticed something I didn't. The lug nuts. My previous wheels had a cap over the lugs so you didn't see them. However, my new wheels don't have that, so you can see the lug nuts and they didn't look that good up against the black wheels. Erik called and offered to order me some black lug nuts to soften the appearance on my new wheels. All in all, Erik went above and beyond to take care of me and make sure all was done correctly. Great guys. Great to work with and over all i highly recommend this place.

Excellent service - fast, great value, friendly, easy to work with…read more We had caught a nail in one tire and need routine rotation as well. Pulled in and was warmly greeted, they had me in and out very quickly and the price was very very reasonable. I had purchased the tires from Costco (they offer free repairs and rotation), but scheduling to get the vehicle in can be a very long wait. When you have to get it done NOW, yeah, it's worth paying a little to get it done immediately - and Big O took care of us with very little out of pocket...and quickly.

First time I came here was for a basic oil change, since then it has been about 3 years now trusting these guys. Ken is the owner, him and his team are quick to respond and have a great system when getting your vehicle worked on. They will send you a link with a break down of the work and cost before proceeding you will have to sign it. I had a couple of my trucks with an oil leak, their mechanic Jimmy is the man. He has fixed a couple of my trucks and I just couldn't be happier. If you are looking for a good auto service place this is the place you can trust. Give them a try and I promise you won't be disappointed. Thanks again Ken and your team for always taking care of me.
