Great people the best in N,California,I'm super happy cheap and fast,try it your self-thanks again Mr David and Mr mike

Same place as the other one listed. Dont waste your time go somewhere else. This place is a rip off! Bait and switch experts! read more

Great work. Had me in and out in record speed! It was a flow of cars being rolled in and out! I would definitely recommend this Smog Center!

Used to come here exclusively because it was the cheapest around. The service here isn't great. I called on 2 separate days, no answer, no voicemail. Went to the shop during business hours and was told their machine was broken and they couldn't do a smog check. went to another place around the way. read more

I've been going to the Smog Center for years now, I've always been greeted warmly and helped promptly. There is a coupon for your smog check in the Contra Costa Times. It doesn't matter if your car is new or old they can perform a check for you! Why pay more? Save time and money and go to The Smog Center! read more

DONT BRING UR CAR TO THIS SHOP. THEY WILL RIP YOU OFF. Guy tried to charge my sister $80 for a smog check. He also refused the discount from groupon. Good thing my sister saw the actual price online and showed it to him and so he dropped it down. But if she hadn't said anything he would've charged her $80. Never bring your wife, girlfriend, kids or anyone who's never done a smog check before to this place. You've been warned. read more

I made the mistake of going to this shop without reading the reviews, low first, not Yelp sort, should have known better. I had a coupon from the newspaper and I asked if they would honor it and as my car was a 2009 it qualified for the $26.99 price plus the $8.25 certificate and I agreed to this. They did the smog check and the car passed easily. Then they tell me that the bill is $50.00 and point to the statement on the coupon that "extra cost may be substantial". This usually refers to 4WD, lifted or some other out of the ordinary feature. My car was an absolutely stock 2 wheel drive and because of the year didn't even require the Dyno. They were done in 5 minutes. They demanded the $50 and since I was naive enough to have trusted what they said on the coupon and not actually get a quote I had no choice but to pay. The bottom line is this place is basically a ripoff shop and they use the "extra cost may be substantial" to charge whatever they want. They have no ethics whatsoever. AVOID THIS PLACE AT ALL COSTS read more

Have been using them for 10 years plus. They had some other guys in there before that were very friendly and remembered me. I have 3 cars and 1 truck, so I've literally brought them TONS of business from just my vehicles alone... (Lexus IS250, Chevy Silverado 1500, Hyndaui Accent, BMW 528i) Not just that but I've recommended and come down to their shop with 2 different people in the same day to get a smog, plus 2 others at different dates. 3 of them passed and 1 did not. I also did not with my 2000 chevy silverado 1500. Nothing major so far, but that's the backstory and the business I've given them thus far (1000's over the years). Well after my truck failed, I was charged $80 bucks. Never bothered to look at the website until a month later after I put my Catalytic converters in my truck. Where things go downhill for me is when I show up in my truck again - fixed and ready to go. However, I mentioned the don't pass don't pay I saw online to the OWNER, he asks "where's your coupon?"... I replied "States that on your website". I then asked him about the payment to the truck I had done and he asked me for the reciept, which was my fault for not bringing, but the same truck should show in the system... no? Either way I was treated poorly by the OWNER and wish the other guys still worked there. The fact they only take cash and check (no one carries checks anymore), plus never mentioned the pass no pay DIRECTLY LISTED ON THE WEBSITE, and then proceeds to make it sound like I need a coupon code to get it = shady and a real money hungry person. Guess what Mr VanDam Smog Center look alike, I'll spend my thousands elsewhere! You're overpriced and don't offer coupons like anyone else anyhow! Not sure how everyone else was treated, but I can't imagine I'm the only one treated like a broke, unwanted guest, that's just wasting their time. You guys SUCK and I'll be happy to say it to your face directly. Just remember the ugly black Chevy Silverado that came in on 10/21/19 and how shitty you treated me. Hope 80 bucks was worth all my future business. I'm sure the other 6 people I referred have something to say about their experience as well. All referring to you as a shady guy - you know what I mean! "leave it here for 6 hours..." Alex- read more

I had my 2008 Acura TSX smog tested last week. Quick service, less than 30min with one car ahead of me. Clipped coupon ($28.99) in East Bay Times. After all paperwork was done and results transmitted to DMV, $40.00, cash only. I'll be back. read more

Awesomely fast and friendly service! I walked in and there were no wait, in and out in 15 mins. They honored any competitors coupons but you need to make sure that your competitor's coupons have no hidden fee. I have this coupon and my Out the door price was $35 (STAR, not Test only) as they advertised! The gentlemen there were very friendly and helpful. He helped me uncovered all the hidden fees of the coupon. I am going to post a picture of the coupon that I used. I think this one is the least confusing. Other additional fee may be applied for truck. (We brought our truck here too and it was not much difference. maybe $10 more) Anyway, this place is very reasonable, legitimate and get smog check done with certificate automatically/electronically sent to DMV. I am very happy with the service. I'll attach the coupon here too. The gentle man said he'll honor this on your phone too so download it and bring it in. No need to find any newspaper. read more

D Smog Center - Auto Repair Near Me - Concord, California

I was here twice, first time two years ago with a coupon from their website. It was not friendly but quickly over OK. This time they tried starting to work while denying to give a quote/price. Very shady communication. I was sure to pay $5-10 less somewhere else but wanted to move on quickly. They regularly charge 80! but where nice to offer me $50 for my "SUV". I'm sure my car was ok because it's in good condition, the test however took no longer than 3 minutes. When I paid (only cash) he snatched the money from my hand/wallet so fast that at the end I couldn't even be sure how many 20s he took from my hand. Honestly I was speechless. IF I overpaid 20 be happy with it. I'll never come back and I hope many others don't fall for the fake reviews and look for the real ones of real people. There are ways to determine between them. I like a tire shop nearby that is really really good. This smog check center here levels the performance of the area back to average. What do they say above? MEH there is better around! read more

Bad service. When I got there had to look around for the technician. When I found him he asked me To drive by car into the stall and open the hood. Went there because of the a coupon which said 26.99 + 8.25cert. But they charge you xtra for Star + 10 and test only + 10. Ended up paying 55 buck for a 06 toyota. They're not upfront with the price either because they will not say anything until the service is complete. You will also have to drive your car out of the stall. read more

Quick and easy process. A pleasure to work with these gentleman! No wait and was complete within 15 minutes.

No bullshit smog service. Tell them you have the online coupon from their website and it's $45. Never had to wait, always in and out in 10min. Have brought four cars here, Lexus ISF, B7 Audi S4, Golf TDI, Subaru Impreza. Also, if you don't pass, mention the online ad because it's only pay if you pass. read more

Fast, efficient, and friendly service at a great price. I'm so glad I found this place!

This place gets ZERO stars...avoid at all costs! Dishonest, False Advertisement, HORRIBLE customer service, and way overpriced. I went to THE SMOG CENTER (address should really be 2241 Monument blvd, Suite R & S, concord) today and had the most horrible experience ever. Gave them a coupon my dad found for a smog chk, saying its $26.95 + 8.25 for the certificate...expecting a total of about $40. The guy tried to charge me $80....then finally believed that I had a coupon...so then he charged me $60 because they added on extra charges ($10 extra for being test only even tho their business is a test only center...wth? Also $10 extra for some part of the smog test that was not included?). First of all, who the heck charges $80 for smog chk? Are they serious? I'm still annoyed about paying $60 for a smog check with a coupon applied, I could've gone elsewhere w/o a coupon and pay less than that. read more

Yikes! I went in into "The Smog Center" to get a copy of a certificate the previous owner of the car I had just purchased had failed to provide. I had called prior to coming and said he would print me a duplicate, but seemed to disdain me. Either it was a different guy or the same angry guy when i got there who seemed resistant to speaking english. When i explained what i needed, he said "no no no, it's not theeese simple my friend". I mentioned I had called earlier and "may have talked to him". He was interrupting me halfway through to say that indeed, I was wrong about... I'm not sure and walked away. (?) I persisted and asked again. Despite no one else in the entire shop, he gives in and looks at the CA.GOV printout that said I had the test done at that shop, then asks if "I had used the lost test results to wipe my ass with or something?". Well, no... But I am using them to write your Yelp review. Additional notes: the sign "Smog Center" was written in red electrical tape in the window), and the other half of the shop was selling strange persian artifacts and what looked like knock-off persian rugs. The guys cat appeared to be wearing false eyelashes and had dandruff. read more

I received a letter in the mail from DMW that I need smoke check. I was at my CPA's office and drove by another smoke check station but the mechanic was lazy and didn't want to take me so I went to this place. I had been here before with my friends car and had no problems. Today the owner was very busy but squeezed me in. I saw him running around trying to minimize the wait time. I appreciate when somebody shows they care about their customers. I will be a loyal customer of this station. It's kind of hidden so you need to know where you going. Parking can be though and there is a limited space read more

Great customer service and price. You can't beat any other price out there. No scams or hassles honest workers. Planning on going back there when smog is needed again. read more

Had my father go here for his older Nissan and was told his car wouldn't pass. The initial test showed really high (PPM) numbers to prove it. They offered to get it to pass for $390 if he left the car and maybe they would have it done by the end of the day. He tried to negotiate with the owner, but he was only willing to lower the estimate to $350. Luckily, he declined the service due to the high cost and no explanation what they would do to fix the car. So he took his car down to street to 'A Perfect Smog'. My father explained that the car might not pass due to the last test, but within 15 minutes the car passes SMOG! They also gave him a competitive price with no haggling. I DO Not recommend going SMOG Center. Seems like they prey on those who don't know much about cars. read more

Only take cash or check. Place seems to be ran by sketchy people. Also there price is expensive compared to other local smog places within the vicinity of it. read more

Coupon from pennysaver said "don't pass, don't pay" and so I took my old truck there. It did fail and they did not charge me a dime. Fast service, spartan waiting area. There was a cat in the waiting area and it's fur covers the sofa, if you're allergic (I sat in the leatherette chair since I am very allergic to fur/dander; there's enough ventilation I didn't have any issues). They have two bays and had two techs when I visited. I found them friendly enough. If you want fake smiles, wireless, and free coffee, maybe this isn't the place for you but I was pleased with the service and shall return. Another reviewer complained that their final bill was higher than the advertised baseline price, but on the ad it clearly states the additional fees: 1) EFT (electronic transfer to DMV), 2) certificate fee, 3) +$10 for trucks/vans, 4) +$10 for EVAP (pre-95 vehicles), 5) +$10 for test-only -- however all SMOG places charge this way, I did not see any misinformation. FYI, there are a few restaurants within walking distance. There's also several auto mechanic shops in the same building, including RedLine auto which I use and have rated 5-stars here on Yelp. read more

Excellent and FAST service. I was in and out in 10 minutes and, while I was waiting, everyone there was super friendly. During the week is definitely the best time to go. Great pricing, especially if you bring your coupon! read more

Hello Everyone Ive been coming to this Smog Station for at least 10 years now. I will NEVER even think about going Anywhere else. The Man who owns the smog station Is VERY TALENTED! I've had a few different vehicles newer ones, older ones, many makes and models. And of course they needed smogs. You get the BEST SERVICE HERE!!!!! Hands Down This Man does everything (He legally can) to pass your vehicle But if it doesnt :( He will let you know what is needed then gives you the "failed read out paper". And tells you to come back when youve corrected the issue. THEN YOU PAY ! its a NO pass NO pay station !!! I always get the coupon in the Penney Saver online But actually HIS PRICES ARE ALREADY REASONABLE!! I HIGHLY RECOMMEND THIS SMOG STATION BECAUSE THEY ARE THE BEST BY FAR . GUARANTEED AAAAA read more

If you're a substance over style kind of person you won't be disappointed here. I stopped by on a Friday afternoon and was taken in almost too hastily and within no more than 20 minutes I was in my car driving with all my smog papers signed off. Yes it's cash only, and I didn't even attempt to use a coupon. read more

I took my car to the Smog Center for the second time. First time 2 years ago and just a few days ago to have the car smogged. I was greeted very warmly. The owner and mechanics are very friendly and efficient. I was #2 in line and my car was done in no time at all. Since my car is an older one, DMV required a Star Station to smog it, which the Smog Center is. Their price is also reasonable, especially if youu have one of their coupons which you can find in the CO CO Times. I would recommend them any time! Gabriele O. read more

Just had my smog done, I've been coming here a couple of times. I like it. It's fast and has always been an easy process. My car passed and I got a good deal. Every time I've come here there hasn't been much of a wait. It's also close to the Mexican food spot so you can walk across the street and come back and your car is smoged. Five Stars read more

Waited till the last minute called at 430 pm and asked for help with my smog he said come on down I was there in twenty minutes and fifteen minutes later I was driving away with my certificate very fast and affordable would highly recommend. great job and I will return with my other vehicles in the future. Thanks again for the prompt service a person like me does not have precious time to waste!!!!! read more

I've been going here for years because of the coupon price and the "No pass no pay". I was there on Saturday 12/1/18 and I was out of there quickly. One downfall is they take cash only. read more

I've used the Smog Center for over ten years, but the last two visits involved their taking my car to another location to have the smog test performed. This involved a lengthy wait while other customers also stood by. The owner said their computer system was down, on both occasions. Prior to these problems I would have given them five stars. I don't plan on using them again until they get their computer problems sorted out. read more

First he charged me $80,then $60 then when I pulled $50 from my wallet he said, I'll take this. $80 FOR SMOG!

Good experience. Called and got an appointment for a short time later on the same day. Found this place because I was looking for a pass or don't pay offer because I have an older car and didn't know if I'd pass. I passed and the guys at the shop were very speedy and professional. It's a strange location with antiques and cash for gold businesses at the same location. It made for interesting things to look at during the short wait. I'm giving them 4 stars instead of five because their actual price ended up being $10 higher than their initial quote and this was with my coupon. read more

They offer an "Iranian" discount. 40% off if you speak Farsi. We went back with our receipt when we found out this little secret and they gave us $30 back from the $80. read more

Told me after they had done the smog that the credit card machine doesn't work. So I'm on a hunt now for an ATM for $80 smog that also said on coupon $25. pathetic. read more

Came down here on a whim and they did my smog in no time! Signed in did some paperwork real quick handed off my Keys and it was just as easy as that Passed my test got my certificate $80 later These guys are friendly and happy to work with you! I'm definitely coming back again. read more

I have used Smog Center for a few years . They are friendly, fast and efficient. Their price is comparable to other smog station. I recommend them. read more

It only took about 20 minutes. I came here a couple years ago for a smog check. Convenient because they are open until 6 pm on Saturday. Thanks! read more

If you're like me and hate paying for smog tests... look no further. I spent days calling around for the best price. This was IT by far! Grab their coupon from http://www.smogcenterconcord.com/ and enjoy a speedy in and out smog for the best price I could find. Mine was $35 cash out the door. (yours may be a little higher cause it depends on your car) So bring your CASH, call ahead if you want (but drop in was fine for me) and get that smog check outta the way as cheap as possible. Also, while you're there waiting for 10 minutes, you can check out the cheetah painting on the wall or chill on the couch. : ) This was my second time here, and I'll be back again in two years. (I forgot where I went 2 years ago, so I researched again this year, and came up with the same result!) read more
