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.

As…read moreI'm new to the area of Cordelia and right in the middle of either going to Fairfield or Vallejo as they're about the same distance, I sent out a quick project request for a smog check, to business to see what the costs are. 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!

When I left the shop around 2:30 today I forgot my backpack which had my work laptop, chargers, portable power bank, and keys. By the time I realized my mistake the shop had closed for the rest of the weekend (they close at 3:30p on Saturdays and reopen 8a Mondays). I called and left voicemails, emailed and texted, hoping to get the owner to return to the store and restore my bag to me. 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.
