Friendly and fast service, Star certified Smog testing done right. Despite Google, the business is still open! They switched fuel brands from Shell to Marathon. Same company read more

The guys here are awesome! I come here to fill up my bbq propane tank as it's the best deal in town!

Service was excellent, fast, friendly and reliable! Definitely recommending this place to everyone I know!

Smiley's Shell Service: A Gem for Smog Inspection A big thank you to Smiley's Shell Service station for their excellent smog check service! Everything about the procedure was really easy, fast, and efficient. The encounter was enhanced by the staff's friendliness and warmth. The reasonable pricing also took me by surprise. Finding a location in our area that continues to provide this crucial service is a comfort. Strongly Recommended for Smog Service. read more

All the guys here are respectful and conduct business as it should be done from filling up propane tanks to smogging a car/truck . Only place I've gone for years! read more

Great service super helpful and friendly. I go back every time and would recommend to anyone.

In and out in 10 minutes. Very reasonable price from a STAR Certified Smog and Repair shop. Staff knowledgeable and no superfluous chat. Results transmitted to DMV after 2 hours. read more

Smiley's Shell Service - North of 99 freeway on Martin Luther King. - Smog Check Stations Near Me - Merced, California

Over priced, bad service and availability, and place is run down and crappy. Go elsewhere

I had previously used another local shop for STAR smog. Last year, I was refilling my propane tanks and remembered I needed the smog done. I decided to give them a try since I was already there. I have been going back for my vehicle smog since (3x). Smiley's shell service is my favorite spot now. They have always been professional at doing their job. They are also cheaper than the last spot I was going too, for the same service. read more

Have been bringing are Toyota Tacoma and Corolla here for the last twenty years.Great fast service.Both vehicles have always past with flying colors. read more

Great people. Was able to smog vehicle that no body else could because they said there computer didn't have the newest software. Smileys did! read more

I recently had to take my two vehicles in to get the smog checks done and I've gone to Smileys for years because of the great service. The tech, John, is very efficient and had both vehicles done in about 25 minutes including the paperwork. Due to my past experience with John, I knew it would be done quickly and once again he proved me right! We got there on a Saturday morning at 8:08 and we were done at 8:33 and that included all the forms and the payment. They start taking vehicles at 8:00am so if you want to beat the normal line, get there early. When we left there were four waiting but I'm sure they were also out quickly. Thanks again, Smiley's, and I'll see you in two years! read more

First come first served. Very good service but all employees unmasked. This should change because social distancing was difficult in the office area.' Price was reasonable and the tech was personable. read more

Went in to get my car smogged, pulled in front of bay to ask if they had time and instead of greeting me or listening to my question the old man pointed at a do not block bay sign and told me when I parked in their lot he could answer my questions. Service is a person to person action and this location simply failed at human interaction. read more

Just smogged my car. In & out in 10 minutes. Only $48 for my vehicle. Been getting our cars smogged here for many years. Service folks are always friendly & professional. read more

Guys here are very knowledgeable. Was nice enough to help me with getting my dad's chevy truck smogged and letting us know what was going on with it so we could get it fixed and then again with my bmw z3. also probably the cheapest place in merced to get your car smogged. read more

I have been taking my vehicles here for smog tests for the past six years. I stopped by yesterday and the place was packed. I went elsewhere but because this was not a Star Station I had to return Shell. My experience was great as usual, they had two technicians working and I was in and out in no time. Thanks to the Merced Sun Star coupon I only paid $35. Keep up the good work everybody! read more

Great service and very helpful. They get you in and out and make sure you understand everything on your smog results. Would definitely recommend to others. read more

Cheapest in town. Very affordable. In and out in good amount of time for smog check. Would recommend it.

I went to get a smog check, I have a severe tremor disability which causes me issues to fill out forms. when told to the man clerk, he said to bad you have to fill it out, I couldn't even print my name. Needless to say, I had to go somewhere else. If you have a disability, they aren't nice. read more

The smog test was good. The coupon was no longer used ( 11/24/2021) but the price was still good. No mask was used with all employees there.

Excellent customer service when I took my van in for a smog check. After being there a week before and didn't pass smog (I was shocked but found out it didn't pass because I had a new battery installed and something didn't reset correctly) the gentleman was so courteous and remembered I was in a power chair. I didn't have an appointment but when he saw me pulling in he met me and instructed me to pull around to the service area and didn't require me to even get out of my van. Everything was handled quickly and efficiently including paperwork and payment while I sat in my van. I wish I could remember his name. Highly recommend Smileys. read more

Always great service. I always take my cars here to get smog'd. Cheap, friendly, and fast service. read more

Smileys needs to train their employees in public relations.I always get all my cars smogged there and usually everybody's pleasant.Today,I went to get my bbq propane tank filled.The employee came out,didn't say squat,no hi how you doing,nothing.I felt like a idiot thanking him when he gave me the tag to pay with.He wanted to get back in the a/c to play with his phone. read more

As crooked as a business gets, they would not pass my vehicle for smog for something I had never been asked for before, keep in mind, I have proof they gave me, emissions wise, my vehicle passed with flying colors. Wasted my time and made me get them information they asked for to pass it and when I come back the same gentleman that told me exactly what to bring him (John) tells me, "Sorry, that won't work." Are you kidding me? You told me exactly what you needed and I went out of my way and spent money to get that information that no other smog shop had hassled me for. Keep in mind my vehicle is a 1997 so this is not my first rodeo. I personally have a friend that would take their Durango to them and they would pass it by putting another similar vehicle on the rack, passing that one and falsifying documents but you cannot pass mine because of something stupid, I had never been asked for before or had an issue before at another smog shop. Mike, from someone who has also been in the auto world, the least you could have done is refunded my money for all the time I wasted going there to begin with (multiple times. Learned my lesson, Merced Smog will be the place I continue to go to, that's what saving a couple bucks gets you apparently, unreliable, lazy work. read more

The guy name Mike who's doing the smog was very unfriendly,could not tell why the car is dying.Our car has been fix by E & J and everything was perfect,I can't see anything wrong on our vehicle. This guys that working for shell need to put their "SMILE" as what is the business names. You guys are grumpy and very unfriendly. read more

I always take my car here when I need a smog check. They're super fast, very experienced and cheap. I had forgot the $10 off coupon they normally run in the local papers and he gave me the discount anyways. Was in and out in 15 minutes. They even have some sort of guarantee that you will pass, but am not sure of the details. read more

My first visit. Friendly, to the point, in and out in less than 10 minutes and a great price. I thought it was all a dream! Best experience ever read more

Great, great place to get your vehicle smogged! I brought in my '94 corolla and there was a little bit of a wait but nothing too long to cause an inconvenience, these guys however gave me $10 off my total and apologized for the wait. My vehicle not only passed but these guys truly made me feel like an appreciated customer. Keep up the great work, I will continue to bring my vehicles into this shop! Highly recommend it! read more

Always a pleasure coming here knowing that I can get my car smogged for a good price and quick. Does get busy sometimes, also the smog techs does help out the customers with what they can. read more

Got to the station at 8:10AM for a smog check. Left with my smog certificate at 8:27AM. These people are quick, efficient and friendly. Been going there for years. Never disappointed. read more

Got the coupon in the Sun-Star for $29.99. Wait not too bad. But failed. So they said drive 100 miles, then come back. Went back next day. They said if it passes it's $8.75 for the certificate (didn't tell me that at time of service but ok whatever) It passed and overall, the technician John was super nice. He took me in like 10 min to closing...very friendly. I'll go back there again. read more

Best in town for smog. Usually busy, so plan ahead.

Went for a smog check with 90's truck, other smog places wanted to charge more because of the year. It was cold in their waiting room and it was nice they run a propane patio heater for their customers. They also have two techs so the smog machine is constantly used so the process of waiting is more smooth. I will keep coming back here. I also used a coupon that I printed online and they accepted it with no hesitation. read more

I give Smiley's a number 2 star rating because on the website it says that pass or don't pay but when I went to get a smog he stated that that was not true it's past or you get a free recheck this constitutes false advertising in my opinion there for netted a number 2 star rating with me read more

Had a smog check and had no issues brought a coupon I printed from the Merced Sun Star. Changed the price immediately, other smog places wanted to charge me extra because of my older truck, Smileys had the same flat rate. I like that they have two techs in the shop so that the work load flows faster. I liked how they accommodate people for the cold weather with sitting arrangements next to a propane patio heater, I will come here again if necessary. read more

I took my truck to get a smog test done. I will say I was pleased with the level of service. From the cashier to the test guy they where helpful and honest. I had my young daughter with me and their interaction was stellar.. I was in and out of the place within 20 mins.. customer service is not hard and very important to my repeat business which these fellows have earned. Now if they had cheaper gas prices I would get gas there as well. Can't beat the smog price nowhere in Merced.. read more

I always come here to smog my car and all the fellas are super nice and helpful. They also respect the customer's time, always being fast and doing a great job with their service. I will keep coming back, thats for sure! read more

best place to get your car smogged. It's super fast and efficient. I thought I would be waiting for like 2 hours, but it only took 15 minutes. They also have snacks inside which you can purchase. This place was recommended by my car dealer, and I will never go anyplace else. thumbs up! read more

BEST AND CHEAPEST IN TOWN! bring a coupon from Merced sun star (or get it online) and get a smog for $29.75. If you don't pass it's free.
