Be forewarned, the basic fee has taxes and stuff that walked it up to $77 out the door, which was disclosed up front, so kudos there. I also made a reservation online but the guy took me early when I arrived, and in about 15 minutes he announced my car passed and provided the paperwork and scanned myDMV form. It's imperative that you bring that to your session. Nice guy, very friendly and professional. They offer a $32 service for expediting payment for the registration same day, but if you have a computer at home, you won't need that. All-in-all, a quick appointment, and unavoidable, but I would definitely come back if or when (probably next year). Pro tip: Fill up your tank and use a fuel injector cleaner from Autozone or O'Reilly's. Most importantly though, if your check engine light is on, you won't pass.

Pros. *There were several forms of posted literature regarding services offered, expectations of the businesss and what the customer could expect. Very good job! *Sam explained the life expectancy of a smog check per DMV regulations. *I scheduled an appointment for 11am, arrived ar 1030 am for a smog check. I arrived early and appreciated, that despite the busy customers, I was serviced by my appointment time. *I can attest that you are able to see your vehicle serviced (if you choose) through a window while you wait. *Water available to drink while you wait. *Service was efficient, quick and Sam did a great job explaining the DMV processing. *You are able to leave same day with new registration & stickers. *Excellence in quality of service to the smog. I am pleased, and currently awaiting my stickers in the mail (as I had already paid at DMV and just needed smog) Cons Restroom needed cleaning. Myself and an older woman both felt uncomfortable at the sight. In all fairness, this is a smog place, not department store. Still, she was elderly and I have disabilities. Clean facilities help us. *Pricing was not clear. On the website was a price that matched a posted paper in the office. However, on the official receipt were additional charges I was not made aware of until payment. Overall, they did a very good job. This business had a constant flow of customers and I could see why. I too, will be a returned customer for my next required smog.

And I do feel bad for showing up right at closing, but I'm being grateful that they helped me out and were so nice about it. Thank you N & K Smog

I was in and out in under ten minutes, and the mechanic even took the time to point out a rat nesting issue and showed me exactly where it was in my car and how to fix it. That level of transparency and care truly impressed me. When you meet people who are sincerely kind and generous, it fills your heart, and this experience absolutely did that for me. I'm honestly blown away. Thank you so much for such a wonderful experience!

Didn't mind as I had purchased Groupon deal--I will be honest at times buying a deal on the Groupon site could be like shooting craps but not for this offer--it was worth it, they did a good job and the equipment they use is up to date. They may not have a fancy, air-conditioned lobby--which is located outdoors under a tarp--it was fine for me as "little heat" on the 25th of August wasn't going to bother me or detract me, nor do they have a big property with lots of parking, which wasn't going to get in the way of me getting my car smogged the same day so my car could meet the DMV requirements. Overall, if you want quick, clear, great service without the frills or gimmicks, Mission Smog Test Only is the place to get your car smogged and get your certificate.

I passed my smog check and was in and out in no more than 15 minutes. After I left, I noticed they even match coupons from other places, which was great to see. Honestly, with the level of service and quality of work, the $50 price was well worth it. Excellent customer service, quick turnaround, and an overall great experience.
