I did have to mention that I was using a Yelp coupon, but once I did, it was applied without any issues and helped significantly with the price. The smog check itself took about 20 minutes. Everything was efficient and smooth, and the staff was helpful and professional throughout the process. I got my paperwork quickly and was on my way in no time. Overall, a quick and easy smog check experience. Would definitely come back again.

SG smog check center got back to me pretty quickly and offered me a great deal that I could not refuse. I stopped by today and followed instructions and and showed the message to the front desk representative regarding the price. She unfortunately stated that they no longer do that price so I'll have to pay an additional $10. At that point I felt a little unhappy, but I'm already there so I need the service done. To my surprise when my car was finished with its smog, happy it passed, they honored and gave me the price that was quoted in the message. The facility itself is pretty quick. There were a few people in front of me, but it felt like I was in and out in less than 30 minutes from start to finish . I'll definitely use them again because the pricing was great and the efficiency and quickness of the people that work there are awesome. They are also STAR certified!

Jazz was wonderful to us on the phone, and you got the feeling that these guys were proud of what they do and they were genuine people, not a shop trying to scam you out of your hard-earned money. They were honest and straightforward in what they did to our car. We have a 2010 Honda CRV and the AC compressor needed to be replaced, which is a very expensive job. We knew it was going to be expensive, but we also wanted someone that we could totally trust so they didn't charge us another $1,000 more. I had a good feeling when we walked into the waiting room. Jazz greeted us right away, as well as the mechanics walking in and out; they all greeted everybody in the room, telling them hello. You just don't get that at normal places. We have never been here, and because of the wonderful reviews, we thought we'd definitely want to give them a shot. We do not regret using them to repair our car. When it all came down to the total $$$, Jazz was able to save us another $300 off the initial cost because he was able to source a slightly less expensive AC compressor for the car. They also follow up with you a week later to see if everything is okay; you get the feeling that this is run by some really good, honest people that don't want to rake you over the coals like some of the other shops. I would highly recommend giving them a call and talking to them if you're hesitant about it. You'll probably have the same experience I did. I would definitely go back to them for any of my car issues in the future.

She called me within 2 hours, agreed to meet me at the shop at 7p, arrived promptly and retrieved my bag, all with a pleasant demeanor and smile. And the contents of my bag were I disturbed.
