I have been a customer of Mr Massoud for over a quarter of a century. He is honest, trustworthy, competent and reliable. And he is fun to talk to, too. I am always looking forward to taking my car in for a smog check, and that is saying a lot! read more

They only do smog so I don't know why it would say Service in the question. Yes my car does require service, but that usually means oil change. They don't do oil changes. They don't do any of that except for a smog and I will say they were very fast promptand because I had a newer car it made it easy. All they had to do is just plug in one of those gadgets value I can get it cheaper, but my husband wants me to go to this place. That's why the four star is cause they're overpriced but then again so is everyone else? read more

Rate to find such an excellent business and proprietor. I got in and out quickly with a professionalism and honesty that is rare these days. Will never smog my car anywhere else. read more

Great service. Very informative and super nice guy. No appointments, first come first serve.

Hardest working guy ever! Honest, friendly, quick. You're not going to be served tea and cake. If you want a smog test, here's your place! I've been to another shop in Simi and got gouged unnecessary fees. His sense of humor can be dry and I've seen another review or two mention that. He's a great guy! read more

Avoid Valley Smog at all costs. This place is shady and dishonest. I took my 2007 Jaguar XJ8 for a smog test after driving it over 900 miles to ensure all monitors were ready. I personally checked with my own OBD scanner and confirmed that everything was good to go. As soon as I arrived, the owner was suspicious and hesitant to even test my car. He asked a bunch of unnecessary questions and made it clear that he was afraid of being audited because he didn't want to pass a car that had previously failed. That is not how smog testing works. If a car is ready and meets emissions requirements, it should pass. During the test, he restarted my car three or four times, which was extremely unusual. I have smogged multiple cars before, and my regular smog tech never does this. Then, mysteriously, my check engine light "suddenly" came on during his test, and he failed me. Coincidence? Absolutely not. He clearly triggered it on purpose to avoid passing me. To confirm my suspicion, I took the car to another smog station three days later--without making a single repair--and it passed with no issues. This proves that Valley Smog deliberately failed my car for no legitimate reason. This place is a scam operation run by someone more concerned with covering his own tracks than conducting honest business. I will be reporting Valley Smog to the Bureau of Automotive Repair for this shady behavior. If you value your time, money, and sanity, go somewhere else. read more

I have a few vehicles in my collection that unfortunately still require a smog inspection and test. I take them to Massoud because of his now familiarity with them, after many years of repeated tests. He still does the required inspection, not wanting to get in trouble with any potential undercover state investigators from BAR (it happens often). He has good ears, once noticed the idle on one of the cars sounded slightly high and recommended lowering it. He was right. read more

As a younger woman, I respect the shop owners honesty and thorough explanation of all details. Will be happily returning!

We drive from Northridge to get our cars smog tested here. The owner is so efficient and so kind. It's worth the drive for the great customer service. Highly recommend this business! read more

Always fast and responsive- bring all my cars here Great service and very friendly. Best value overall in town. read more

second time here and again, great service all around. Massoud is very honest and quite efficient. It's a one man show and man, was he moving! definitely recommend if you are in need of a Smog Test read more

Wow, we loved our experience at the Valley Smog Test Only today. We brought in two vehicles and the owner Massoud was welcoming, kind, fast, and very professional. Our 22-year-old truck didn't pass the first time so Massoud told us why it didn't pass (unplugged battery) and what we needed to do (drive around) and within two hours we were back and it passed. Massoud does an OUTSTANDING job managing the customer flow and making sure everyone is comfortable. I loved his end-of-transaction process and the explanation of the paperwork and what to do with it after we leave. Bravo to this one-man show! Run don't walk to Valley Smog Test Only! read more

Coming up on my 5th smog test and always efficient, punctual and to the point. A pleasure to go there.

Oh my god, Roya and Massoud are SO nice and friendly. They were also attentive and communicative. The parking is easy and it's off to the side so you can sit and relax. Took no time at all for them and they're just lovely people. Highly recommended. I'd give 6/5 if I could. read more

Valley Smog Test Only - Car, Massoud, fans - Smog Check Stations Near Me - Simi Valley, California

Friendly. Fast. Efficient. Doing your smog isn't fun but the gentleman working there makes it an easy experience.

First let me say that these people are very nice but unfortunately they are not always knowledgeable about the cars they smog. After waiting an hour I was told that my car did not pass because of a visual inspection for the catalytic converter. He did not know where it was. How can a licensed repair shop not know how to find a catalytic converter? Sorry you give the two stars but you should really know how to inspect something or at least have the courtesy of letting me know sooner. I ended up at WEST VALLEY SMOG, who got me in and out in 15 minutes. Also super nice but really knew his business and the car. read more

OMG!! Can this guy more rude?!?! You would think business is booming!! I arrived at 1 PM on a Tuesday and he had a car inside already. He hadn't even said hello when he saw the coupon in my hand and immediately declared my F150 ineligible. He asked me thrice if it was modified and apparently STILL didn't believe me because he said he would have to check before he could give me a price. After a few minutes I realized I didn't want to give him my business. Went to R.A.D. instead. Do yourself a favor and don't waste your time with this guy. You can do better. read more

Love this place . Went to get my smog with my little kid and he is a great human being. I would greatly recommend him. Fast job very clean and a great guy. read more

Owner explained process before hand, and was upfront about price. Quick and easy. Highly recommend!

Masood was very friendly, professional, and the smog test was done quickly. My friend was concerned about some water puddling beneath her car, and he took the time to explain to her that it was coming from the air conditioned and was not a problem. I'll be going back to Valley Smog Test Only Center. read more

very pleasant!! Massoud was pretty quick and tried to attend everyone as quickly as he could, in an efficient manner. Thankyou Massoud!

Extremely professional. He took extreme social distancing measures and disinfected his counter after each customer. Finished my smog test quickly. Definitely recommend. There are no appointments, so it is first come first serve, but he finishes each customer's vehicle quickly. Business is slow for him now due to the pandemic but many people still need smog tests and if you do, I recommend this place. read more

Massoud at Valley Smog is amazing. The friendliest most knowledgeable individual. He will advise what is wrong with the vehicle if it does not pass Smog the first time. I cannot say enough about Massoud and his professionalism. If you need to get your vehicle smogged, this is the place to do it!! Thank you Massoud for all that you do for us!! read more

This is my third time here and I won't go anywhere else. I've recommended so many of my family and friends. Fast, friendly and efficient. Still the best place in town. read more

Came to this place on account of tag renewal without an appointment. It was Saturday and they had been very busy. The owner was making sure everyone was at the very least greeted if not checked in and queued. There was enough seating for four people to be socially distanced and comfortable. When I was queued up, the gentleman asked me how my day was and what brought me over, and welcomed me. After waiting for the three others ahead of me to be helped it was my turn. There is one thing I noticed amongst all the people here: smiles. Everyone knows this guy or he must have a lot of friends I thought. Maybe he does but a lot of the people here where first timers as well and he treated everyone with respect and made sure he was efficient with his time as possible. When he was working on my car, he explained what he was doing, and what he was checking for. After he was done and I passed, he explained the DMV side of the process and what to expect. Charged me and I instinctually reached out to shake this man's hand because this man knows how to talk to people but caught myself and just thanked him for his work. If you need to get smog checked, come here as you won't forget it. read more

FAST, FRIENDLY and a FAVORITE. small and clean local business...my type of place. he gave me great information about the process and went over my registration payment options when the test was done. he offered my kids and me some chocolate and we were on our way. great experience. read more

Massoud is a honest, hard working, straight shooter that I appreciate. I've been coming here for about 8 years, and he is very consistent and fair. read more

Always good service here, but yesterday was above and beyond. I had to take our RV in, by myself, for reasons I won't get into. I didn't know how to get the engine cover off, and it gave Massoud a lot of trouble. He took a lot of time and got everything to work so that this stressful (for me) task could get completed. I will be forever grateful. read more

Called to ask about the price and got a clear explanation. Went in and the owners were super friendly. No idea how anyone can consider them anything but nice. The whole process took 40 min with two people ahead of me. I'm taking all my cars in the future and recommending all my friends and family go here. read more

came here based on previous yelp reviews. Was in and out in no time. Guy gave me a discount since I was not working. Pleasant, easy to work with. No problem. Will go again if I need another smog check. Highly recommend. read more
