I've been coming here for years. Never had a problem. He's upfront about what you can expect. Some customers might be unrealistic. Old cars sometimes have issues. read more

My Jeep wasn't ready to be tested, catalytic converter (OBD) wasn't up to working temperature but he tested it anyway and it failed of course. Told me I should sell my Jeep because 4 cylinder Jeeps are too much trouble to smog or go back to the original sized tires, blah blah blah. Maybe he was having a lousy day but he complained about my Impala being a heavy car when he tested it too! Guess they don't have American cars in Vietnam. read more

HONEST QUALITY SERVICE. Come see these guys when in need of a quick and reliable smog check at a great price. read more

We've been bringing our cars here for years and only go somewhere else if the wait is too long here. The owner has a dry sense of humor and it's always interesting to hear his latest take on life in the Inland Empire. I usually drop off the car and walk around the shopping mall for 20 minutes. It's frustrating that California requires smog checks on hybrid vehicles, and the owner said that even electric vehicles will require inspections in the future. Nice job security for him! read more

Whether I am smogging my 2002 Porsche Carrera or my 2005 Ford Explorer truck, Steve handles each as if it were his own car. Flawless customer service. He has never been anything but helpful and quick. I will bring my cars here every time I need to get a vehicle smogged! read more

Steve always gives EXCELLENT CUSTOMER SERVICE- today he smogged my truck AGAIN. I left it with him while I met a friend for lunch at Islands. When I came back, he had put on my sun shades in my window because it was hot out. Please don't go anywhere else for your "TEST ONLY" smog, he truly is no nice and accommodates you while you run errands in the nearby Riverside Plaza. read more

My car didnt pass the first time. He said drive it around for a few days and bring it back. He said he would only charge me for the certificate the second time around. Not true, he charged the full price the second time. Go elsewhere where integrity matters! read more

I was in somewhat of a hurry and I was told about this place. Lucky for me there was no one there. I believe the gentleman that helped me was the owner of the place. He was very nice, helpful, and passed my car! Lol. If I'm in the area, I would definitely come here again. Small corner shop in the ARCO parking lot. Leave the little ones at home. read more

Came to get my car smog checked. The guy is super friendly and had everything done in under 20 minutes. He is also behind the gas station just a fyi. Will be back next time! read more

Great experience. Super quick and easy. Steven was really nice and I barely had to bribe him to pass (kidding). If you are looking for the shop, it shares a building with AM/PM and is on the backside. Look for the smog check flag at the street. read more

Very pleasant and efficient. Great convenient & safe location right at central plaza.

Got a smog check and excellent service. Local spot and you can grab El pollo loco while you wait lol

He has absolutely amazing. I was in and out in no time. No gimmicks no up charge !!! Some smog shop I've been too initial cost $ 19.99 then before I leave it's now $60 for a smog. read more

My normal smog place closed down but I'm glad I found Steven and his test shop. He was really friendly and easy going. Went early in the morning and didn't have to wait. Got me in and out really quickly. Would def recommend him. read more

My car never has a problem passing smog. This time around there still wasn't an issue. Granted, it's $60 now just for a smog; welcome to California. Major issue here is the guy running the shop. He's extremely rude and has a nasty attitude about the homeless. He's convinced that ALL homeless are so because they're "just lazy and don't wanna work". Seriously?! I know several folks out there with actual mental conditions and drug addiction problems that have ruined their lives. I took my car in for a smog and end up hearing a wanna be elitist trying to explain that the homeless are so by choice. Wow. Regardless of how anyone feels about such topics there's a time and place for that. I'll be taking my business elsewhere from now on. read more

Came in this morning for a smog, got it done quickly and had a nice chat with owner. Come here for a quick, reliable, no run around smog.

Bottom line he got another $30 bucks out of me on top of the $50 I had already paid fornothing!!I will be contactingtge BBB on this guy not right! I asked other smog shops & they said no thetesno re-test fee! read more

Steve Thieu has been running his smog-test business at the Riverside Plaza address for years, sharing the building with a convenience-store with gas-station. The latter business has turned over to different ownership once or twice in that time. And Steve has had to replace his expensive testing equipment as mandated by the state at least once to my memory -- I remember he mentioned it. Granted, facilities are a bit cramped with no customer lounge for those hot summer Riverside days. But Steve knows his business, and he knows automobiles. Should I say he gave me good advice as to which later make and model to replace my old SUV? Charges are reasonable; this is an honest and compliant smog-test facility. Steve prefers cash to credit card, but he'll accept the latter. read more

The smog was quick and easy, the price was right, and the owner/tech was actually friendly. You don't get that very often. They are also Star Certified for those of us that are required to get a Star Certified smog from our fine state. read more

Steve is the best ... he has smogged our cars for several years and it is never an unpleasant process. Friendly, fast, efficient and reasonable. In and out thanks steve pam and john read more

RC smog Test only center - Good reviews, Good customer service. I took my car for the smog check. Fast no waiting. - Smog Check Stations Near Me - Riverside, California

There is no waiting room/area or restroom. Waiting outside with the hot weather in riverside was not that pleasant. Note, they charge $60 for smog test on passenger cars. read more

This was the quickest easiest smog check every. Loved it. Very nice, clean. I recommend going there.

I have been coming to RC for years now. Same owner, he is friendly quick with the work and fairly priced. I will honestly never go to any other test station as long as RC is still around. read more

Came to get out truck smogged. I wish the guy would've told us that we had an active monitor before doing the test so we have to spend an extra $40 to do a retest? Jew bag man. Very frustrating. Don't go here. read more

Small place, there is not even a waiting area. Gave the guy the paperwork, he looked at my old piece of sh!t car and said $65 to do a smog check. He said because my car is old so it costs more. Hmm. I called the other place and they said it doesn't matter what year the car is and they charged 45. Not gonna do business here read more

Steve is great. He helped me when I could not get a smog from other smog check places. My previous repair man reset the check engine light and I could not do smog until so many cycles. Steve kept checking the car for free until he was able to smog my 2001 camry--and it passed! Great service and great personality. Thanks read more

Friendly, fast, affordable. I was in and out with 2 cars ahead of me, in about 1/2 hour!

Came here for a smog check based on a recommendation from a friend. Steve was really helpful & provides excellent customer service. I was in & out in no time at all. Steve does a good job & does his best to help out with whatever you need. Will definitely recommend coming here. read more

I highly recommend this place for smog testing. Star certified and he smogs everything. I had an 88' Camry that 5 others wouldn't try. He knew what he was doing and did his job. The car passed. I do smogs, but at the moment my station isnt Star certified and I needed a certificate for my car, because it was directed. So, I come to this place for a reliable smog. read more

Really quick, no frills smog check. The owner is super nice, very helpful, and gets you in and out fast. Price is about what you'd expect ($40-$60). read more

This place is in the back of an arco gas station. I Came here to get my car a smog test and this was by far one of the best customer service. I've been to some and had my car take more than an hour to finish. However in this specific one I was in and out in no time. Steve is the guy and very funny! One of the few honest smog shops. read more

Price was 1/2 of what I paid in Los Alamitos last year. Car didn't pass. Tech explained what was wrong and what I need to do to get it fixed. In and out very quickly, I will go to them in the future, always. read more
