Gary is knowledgable, courteous, fast and efficient. I recommend his service and plan on returning. Great job! read more

The service was great! I went to the DMV and they told me i needed a smog, I came in with my nissan and the owner had it in and out in less than 15 mins, if I am being honest it was probably 10! Smog was 49$ which is a great value considering I payed 60$ at another place with a different car. read more

Super fast and nice guys. They gave me a cold bottle of water and told me where to go to get my engine block steamed cleaned to get rid of the rats. Only $52 bucks! This is also my place to get my car washed as well with a $9 drive through. Thanks! read more

This place is great - not counting my small talk with the owner (Gary), I'd say the job was done in probably 10-15 minutes tops, and there was fortunately no wait when I arrived (no appointment). Because this facility is located within a gas station, maneuvering my car in and out for testing was not challenging at all. Only $45 cash (out the door) for the smog check (4D mid-size sedan), and unlike a nearby competing shop (that shall go unnamed), the owner of this shop did not attempt to elicit a gratuity (said unnamed competing shop also charged quite a bit more in 2023 for a smog test of the same vehicle - $58). Electronic submission of my passing smog test result was confirmed by DMV the same day, allowing my registration renewal to proceed unhindered. Probably the best smog test facility I've ever been to, and I'll definitely be back here for my next smog test! read more

Great and fast service. Gary performed the test I was in and out in under 20 min. Best price in Pasadena

Gary is a very kind man. Quick and wonderful service. Price was good and gave me what I needed. Thank you!

This smog center is within a shell gas station. I called in advance asking if I could still get my smog done without the paperwork(the answer is yes). The Owner made everything easy enough and i formed me of next steps for the whole process. The DMV reporting is also handled and takes around 10-15 minutes to finish a confirmation (after your smog is done) read more

This place was great. The service was quick and the tech was super kind and helpful. Highly recommend!

Gary helped me. In and out in 15 minutes, and I called him while in the area roughly 10 minutes prior to showing up. Friendly and quick service. Also gave me recommendations for a place to maintenance small fix ups for cheap to a nearby repair shop! read more

Went to get my car smog checked here randomly while I was running errands and I'm so happy I did! Gary was so friendly, quick and went above and beyond with his customer service. I really appreciated his knowledge of cars and overall kindness. Great pricing too. Definitely come here if you need a smog check! Thanks so much Gary! read more

I just had my smog check at All Smog Test Only and couldn't believe it only took 10 minutes- I didn't even get out of the car. Gary is just the best.. most helpful and all around nice guy. If you are in need of a smog check, he's the person to see. Thank you Gary read more

Fast, experienced, cheap, and convenient. Will definitely be going back when I need another smog check done.

Best experience I've had. No appointment was necessary when I called so I drove straight there and Gary was very kind and got the job done within 10 minutes. You get $20 off any smog check and it worth the service and expertise. Gary is a gem and I will definitely be coming back! read more

I showed up for a Star Station Smog test in the morning, I was in and out in 10 minutes. Great service, awesome job done. I have no complaints. No issue with the pricing too. Very reasonable and I definitely did not feel like I got ripped off and shaken down (like a lot of other reviews say for other places). Highly recommend! read more

No need to make an appointment, Quick service Friendly knowledgeable owner Price is extremely competitive read more

Found this location near me when searching on apple maps with great reviews. I came to have a star certified smog test to renew my vehicle. It is kinda connected to a Shell gas station. I came 30min before closing and asked first if I could get taken in and he kindly agreed. Gary really cares about people and has outstanding character. He values honesty and fairness. He told me the things I needed to do for my car's specific needs, and my car passed the test! Truly a gem because of him! The cost was a great value! Bonus: it was late afternoon on a hot sunny day, and his cologne still smelled great! read more

I came here after work, it was already closer to 5 which was closer to closing time. I spoke to Gary and let him know I was 15 minutes away he said that it was fine and that he would wait. I arrived a few minutes before 5 he was very kind and super fast! I was out of there within about 10-15 minutes. I was expecting to pay a lot but when he told me the total super affordable! From now on I will be coming to Gary for future smog checks! read more

Gary is awesome! He took really good care of my car as I brought it for a smog check. He knows a lot about cars. Fair price as well. In and out in 10 mins. I highly recommend it. read more

I was at the Rosemead DMV location and called several places but decided to come here and it was a very good choice. He was fast, detailed, and took me immediately. From start to finish it was no more than 10 minutes. He was even clean and I could stay in my car with the AC blasting on this hot day. AND he brought me a cold bottle water. It was $45 cash. Best price always wins! I'll def be coming here again!! read more

I went to get a SMOG test today at "All SMOG Test Only Star Station" located at the intersection of San Gabriel and Colorado Blvds within the Shell gas station. I was told it would cost $48 (via credit card) for the test and after about 10 min, the test was complete. The attendant wanted me to make payment, but I noticed that the report said that I needed a retest. When I asked why I needed the retest, he was unwilling to explain and insisted that I make the payment first. After some back and forth, he said the computers would not connect and that was not his problem (which made no sense to me). I looked at the report which indicated that after driving 50 - 100 miles, I could retest for another $35. It almost seemed orchestrated that he was trying to get more money from me from the get-go. Reluctantly, I still made the payment (even though I felt that I shouldn't have) but we exchanged unpleasantries and he told me not come back. I got charged $39.75 for nothing - I guess the cost is $8.25 less if you have to retest : 0. What a rip-off! I would give this SMOG station "zero" or even better "negative" stars, if possible. No way to run a business IMO. It would've helped if the guy was able to communicate in English properly. read more

They did not properly file paper work to the dmv about my smog test pass and my car got towed and was impounded. I will be suing this business. read more

830am on a rainy day, I called and Gary answered. He is kind, quick and easy going. Gave me a good deal for a Smog Star Cert. Really appreciate the promptness! read more

It's Saturday 3pm and I needed a smog check done ASAP for my registration, most smog locations were already closed at 2pm but not this location! Got me in and out of there in no more then 15 mins !! Sheesh not many can do that but they can! Best price in town 48$ can't go wrong! read more

Getting my car check can be so stressful. However coming here is a positive experience. You are treated so well so respectfully. Owner is just a lovely man. It's my second time coming here. He is still so nice so helpful. So happy I was told about this place. read more

Fast, fair and great service. Owner let us know my vacuum hoses are deteriorating so I will replace it accordingly. Thank you.

Getting a smog check can be every bit as stressful as a visit to the dentist. You never know what they are going to find. Well, this is my first smog check experience in like seven or eight years, and now being far removed from my old favorite place, I looked up Nearby Smog Check and this was the closest to my home as luck would have it. Open on a Saturday! Open until 4! Experienced and efficient Gary attended me, and what a great thing it is to know a great neighbor and business is only a few blocks away. Helped me out with my last minute smog check. read more

Great and friendly service. Gary helped me today and was very kind answering went above and beyond.

I have been coming to this location for 8 years now, every 2 years to get my car smogged. Gary is absolutely wonderful technician who has always taken great care of our vehicles. Not only is the service quick and easy, but he always offers great advice on how to keep the cars running well and how to prepare best for the life of the car. He is very honest and trustworthy - I will not go anywhere else. On top of the wonderful service, it is the lowest priced smog test place around. I very highly recommend this Shell station!!! read more

Gary is amazing, friendly and efficient. I want to thank you my friend for great service today, I really appreciate it.

Gary is such a nice person, and he got me in and out in no time. We had a nice conversation while he performed the smog test, and he offered me some water while I waited. The price was far better than anywhere else, and it's good to know that one is supporting a good guy's business. Highly recommended. read more

I needed to get a last second smog check, and decided to come here. I was not disappointed! It was my first time going in for a smog check, and Gary made it very easy. I was out of there in 20 minutes tops. He was very kind, quick, and efficient. Highly recommend! read more

I'm leaving this comment so that next time I need a smog check or my friends need a recommendation, I know where to go. I went in for a smog check today. The owner didn't greet me with a smile or try to do small talks or whatever, not that I expected him to...but he was fast, the service was inexpensive. Everything was smooth. It was a warm sunny day and while I was waiting inside, he came over and handed me a bottle of ice water. Very unexpected and very much appreciated. I thought I should write a review as a thank you. read more

Found them online. Super quick and easy. Very friendly service - definitely return.

Gary is the best!! Gary makes the smog test enjoyable and fast. My family and I all take our cars here and we've been taking them here for years. He has the best prices and offers $20 off all smog checks. He's given me plenty of car and life advice that was worth way more than the cost of the smog check. Great guy, highly recommend! read more
