Been coming here for so many years with multiple cars! Fast service as long as there is no line. You also just stay in your car. All the staff that has helped has been nice. I highly recommend! read more

I went there yesterday. In and out in about 5 minutes. Of course if someone was in front of me in line it would take longer. Fast, easy, not really friendly but not unfriendly either but I didn't go there for conversation. I went there because I hoped it would be fast and efficient and that is what I got. You stay in your car and he does all the work. I definitely recommend them to anyone who lives nearby. If you live further away maybe there is a different fast and efficient company closer to you. read more

Very quick service. Was able to stay in car during test. Got in and out in less than ten minutes . I drove up 5 minutes before opening. Definitely sign up for the $15 coupon (August 2025) on their website or email list for even better price. Fantastic service and would definitely go again. read more

I gave Simi Test Only Smog Center a try since they are local and I needed quick service. The smog check took no more than 10 minutes, and everything was fast and efficient from start to finish. Customer service was great, the associate was friendly, and checkout was quick. Also worth mentioning, they have a $15 off coupon, which was a nice bonus. Overall, a smooth and convenient experience. I would definitely recommend them. read more

I went a couple of days ago expecting the usual long, boring wait where I'd have to get out of the car and just sit around. But wow, was I in for a surprise! I pulled up, and the tech, Kaden, waved me right in to a stop. I rolled down my window, handed him the paperwork, and didn't even have to get out of the car! I was in and out in just 7 minutes. Super quick and super convenient! I would highly recommend it! read more

I'm from Oregon and I just moved in with my girlfriend here in California and I didn't know where to start to transfer my car. She told me I needed a smog check before I headed to the DMV, I had never even heard of a smog check so I was a little anxious not knowing what to expect. It was such a quick process and the owner, Ace, was so personable and helpful and it was a lot cheaper than I expected (only $65). Ace was so super helpful explaining what I'd need to take to the DMV and what to expect. Highly recommend this location to anyone in need of a smog check. read more

Definitely a place I will be bring my car back again.. I moved from the valley in sherman oaks and I had a go to guy every year. Since I really don't know this area well, I was hesitant to take it to a new place and was willing to drive all the way to sherman oaks to smog my vehicle. But for some reason, I decided to just give a place a chance in the area and I'm so glad I did. The older gentleman was precisely that. A gentleman from start to finish. I have an older 2008 vehicle with 178k miles. I was in and out in 15 minutes and thats with a person ahead of me. Don't expect the man to work miracles if you don't take care of your vehicle. He's there to do one thing, and that is to conduct the smog test. He's not a mechanic and he's not your servant. If your vehicle doesn't pass, pay the fee and go pay someone to fix it. I would definitely recommend this place to anyone. Ample parking all around. read more

I had my smog check here today. Quick service plus I stayed in the car the whole time, I like this place !!!

Received the "star smog only "requirement this year for our 2011 Nissan so we found Simi Test Only through yelp, found the coupon and today we rolled in about 1pm and in and out within 15 min with a passed smog test . Frank was a nice guy couldn't have had a faster friendlier service . I would recommend them. Note we did take notice of the previous reviewer who mentioned if we had work done recently to wait until the engine "cycled" or something to that effect , and we just had the 90k service so we waited about 30/45 days and passed like a champ. Thanks for that tip. read more

Went for a smog test. Super efficient and friendly. I was in and out of there in 10 minutes! No complaints here.

Highly recommend going here!! Had a lovely experience. I wish I had got the name of the gentleman who helped me, he was very sweet and knowledgeable. Definitely will be back and will recommend to anyone who needs to get a smog done. read more

Kind people in a a harsh world......He was very good quick intuitive answered all my questions..A good man and Honest.....

Called up to see if they do RVs (which they do) and was able to come in right away with no line. Ace was super friendly and had me in and out of there very quickly. Will definitely come back for smogging my other vehicles. read more

Always fast and straight forward with pricing. They'll even get you your tags (a fee) if you don't want to wait for the DMV to send them

These guys are always quick & courteous.....have taken many vehicles there without a problem.

Super nice owner, great small business. In and out quickly without having to get out of my car. Honored coupon, great value. Conveniently shares the building with Oilchangers.com. Open on Saturdays! read more

Rolled right in, was immediately helped and got the smog check test going! These guys are fast and incredible! Pricing is very fair!

Easy peasy. Owner was super nice. Had me out in 15 minutes. Highly recommend. Super convenient location.

I don't usually leave reviews but wow - worst experience ever. Called frank and asked him how long it would take for my car and he said 45 minutes and would cost 79.99. Came down and he began to work on it - about 10 minutes in a second car with a lady driving came in and he completely stepped away from car and started working on her and completed her car and then came back to my car. I didn't say anything and continued waiting. 1 hour and 30 minutes later frank finished. In my marathon of a wait I found a 15$ coupon on his website and when I ask him to redeem it - he said that is for 2000 or newer vehicles. I asked where it says that and he said look how long it took to do your vehicle. I said that's not really fair frank and he said I know it's not fair and SMACKED HIS HANDS TOGETHER AT ME THREE TIME said give me the card right now 65$ and never come back again. Got angry with me and said it took me all this time and this is the last time I do work for you. Took my paper and left shocked at how he treated a first time customer. Will never be back. read more

Great service. You can get smog,register and get you tags . One stop shop. Great hours

I had my RV serviced a Smog Test pre checked and it was running great. It passed the under hood visuals and emissions tests no problem but the unfriendly guy acted like he was determined to find a way to make it fail. Having me remove the engine cover inside the cabin and spent a few minutes looking around then about 20 minutes with a mirror and flashlight in the engine compartment and the underneath and then repeat a few more times. How many times do have to see the factory exhaust and catalytic converter? Then the prick charges me double ,$99 "because it's an RV" nobody else does. read more

I always go here for my smogs on my vehicles and today I met the owner Ace who was by far the nicest, down to earth guy. He not only took care of me in a very timely manner, he also chatted with me the entire time as he performed the smog on my truck. he was polite, friendly and great to talk to. Thank you Ace for A+++ service, I will always come back here. Highly recommended. :) read more

Went in a week ago to get a smog test and my car didn't have enough "data" due to sitting not driven in awhile. We drove it around for 100 miles & it passed! David was super friendly & helpful! Will use this place again if we need another smog test. read more

Wonderful experience!!! Super friendly and professional services. I had to get the Called ahead and I had no waiting time.

I went in and was done in about 10 minutes. Was the only customer. Didn't see any mention of price until I checked Yelp and saw the invoice. Even with a $15 coupon, it was almost $50. There's places a lot cheaper out here, but they're probably busier. Not sure the speed made up from the extra $19 I spent. Without coupon: $64 With coupon: $49 read more

I am giving 2 stars because they did a good job with the smog check but they advertised the price at $29.75 in Savings Magazine and I paid $45. All Smog Check ads say + Certification & Transfer fee. Certification currently costs $8.25. The transfer fee is to cover the cost of transmitting the data to the State. Online it says that this can be from $1 to $3. I think everyone has Wifi now and that there really shouldn't be any Transfer cost but even if they charge me $3 for that, I was overcharge $4. I shop around and would have gone elsewhere if I knew they would be overcharging. Get a price before they start if you want to know what they are really charging you. read more

Had an amazing experience here. Super helpful and very quick. I was in the waiting room for less then 10 minutes. The cost of my smog was $65 read more

Many other places are cheaper but I came here to get in and out which I have done before and was somewhat satisfied to pay the extra fee. But this time I bought a used car and after switching out starter I had to disconnect the battery. Which means the Cpu resets to factory in cars and I didn't know at the time. You have to drive about 50 miles before being able to smog check the vehicle to be read. An honest man would have told me right away to come back after seeing it not being able get readings on vehicle instead I paid the price and I was told it passed the emissions but then when I went to register it I was told I failed the functionality part. It was due to the cpu not being readable. I went back, was told he was sorry, and that I had to pay for another smog check after driving 50 miles. A second check is free at many other places. He also told me my vehicle probably needs a new cat and recommended me to his neighbors shop which was probably someone he knew. Either he doesn't have a clue what he is doing and/or he is just trying to just make more money off people. Either way I'm never coming back again. The guy seemed nice but I felt robbed. I also passed my smog check at another location for a cheaper price and was told beforehand if i didn't pass the first one the second one was free. read more

Very good service!!! It was so fast & he give me discount. Save time & money!!! Thank u so much

Relatively fast in and out . . . everything you'd expect from a smog check center. HOWEVER, his price for a smog check is $64! The only mention of a price on the website is the printable coupon for $15 dollars off. Foolishly, I never inquired about what price this $15 would be taken off of. Fool me once . . . read more

a lot of complains based on untrue facts . technicians are all state licensed and they sign the certificate under penalty of perjury and this no jokes if the cars failed for pcv system and repaired ; it will extend the life of the engine ; additionally if gas cap leaking and replaced it will save the consumer money . usually the above item are the most ignored items on the cars . consumer should thank the technician based on the above facts . my car is 97 and passing like 2005. read more
