Great service provided by Mission Smog Test Only, although they were busy they were courteous and…read morestraight forward about the wait and what costs were as well as info if car didn't pass. 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. The attendants were great, thorough, polite and they did an awesome job! Thank you guys! ;)

Cheaper than most, considering I wasn't trying to drive 17min for 38$ I paid 58$ for the convenience since it was in my way home and I had other errands to run. Update: the other errands to run were an oil change but connected to this place next door they do oil changes. Synthetic blend was their cheapest they don't do regular, but it was the same price as Lenny dykstras and saved me the trip. Although it didn't come with a free car wash like Lenny's, still very convenient.

Like some of the other reviews mentioned, the service was pretty fast. On the phone he said there was only a short wait. Maybe due to location, a smaller street off main street Magnolia, so there was only one person ahead of me and one person after me. I got there 3:08 pm Wednesday and finished the smog check at 3:25 pm so really about 15 minutes! I liked the two open seating areas, could walk through to front waiting room or stay by car in back seating area. I paid cash and he even confirmed over the phone that it was ok that I misplaced my car registration paper (he could send the pass results electronically). Yay! Thank you, I already told family about this hidden great customer service and low-cost place!
