Steve and his staff went above and beyond on a recent service on my Mercedes. He was fast and accommodating. I would recommend him to anyone :) read more

My place closed so I found a new place. Get their coupon from their website. It took a bit of time but in the end, everything worked out. I'll definitely recommend this place to my friends. Since I have an older car, it cost me, $35. It still a good deal. read more

This place is hard to find which is probably why they gave the cheapest coupons. Having said that they did the test on my car very quickly and I was in and out in about 25 minutes. read more

Friendly service and unbearable price. Don't let those few bad reviews turn you off. Pretty much all of them were the result of customer error and failure to do what you should always do when you get your car serviced, ask questions! He is quick and efficient. They are very good at what they do. read more

Smog N Dash is the place to go for smog checks at a great price! I've visited multiple times and they have always been friendly and provided quick service (about 15 minutes). Also, look out for their coupons in the mail or online which state the price you'll pay. (And don't be fooled by competitors' coupons that make statements such as "$20 off", since you'll only get $20 off the competitors' exorbitant rates!) read more

There was no waiting when I went on a Monday afternoon. The process was very efficient and quick. I was able to use the online coupon for the discount. Will recommend to a friend. read more

This place was great, very quick & easy. The staff was friendly, funny and nice to work with. Everything you want when your looking to get your car smog'ed. read more

Bring my cars here all the time, one of the best spots around. I love the staff and they always take care of me! Ask for Steve he will handle everything read more

Steve and Matt are awesome, took my challenger Srt8 in for a clutch. They did on time and now runs better than ever!! They even went out of their way to pickup some parts!! This place is awesome, they do everything!!! From VW's to Lamborghini and at less than 1/2 dealer price!!! I just can't say enough. Thank you, Ed read more

Made an appointment for Saturday AM. Everything went smoothly and they could even change my windshield wipers which were in dire need of changing with projected rains coming. They were professional yet personable. The shop while small was clean and able to efficiently take care of business. Price was very very reasonable as I'd called around. Couldn't recommend their business more. Made you pleased to have to smog your car with such great service/outcome. Thanks. read more

Excellent service-- quick and efficient. My only complaint is that the location is extremely difficult to find, and there is no useful information on the website for finding it. If it hadn't been for Yelp, I wouldn't have known what back road to go down. read more

Fast Friendly Service at a great price. I called to make an appointment and they said I could come whenever it is convieint for me within their hrs of operarion, no appointment required. I showed up at 3:00 and was out by 3:30 and that was with 2 people ahead of me. I'm glad I asked for directions ahead of time cause it wouild have been a little tricky. I will defintilty refer my family & friends. read more

This place was fast and professional. Got my wife's car in and out within 20 minutes. A little off the radar, it's behind the pho' place. Doesn't look like much but these guys seem to know what they are doing. read more

Took my car in for a smog, but will be back for any future car needs. The best and courteous service I have ever gotten. Ask for Jason. He's the best of the best! Fast and friendly. Good job! Laura read more

The service is quick and OK since no one is in front of me. Get in and done in 10-15 minutes. But don't know why they charge $2 extra if paid by credit card. My car required a star station and there is another $20 extra. Don't know if its standard or ? read more

James was fantastic, best Smog Service I've ever had. I was in and out in less than 30 minutes, with a reasonable cost to boot. Cheers!

I had a very bad experience here and would never go here again. First off, I have five cars (mine and my daughters) and for many years have always brought my cars here for smog testing, with great results. I know a lot about cars, so no newb here either. I scheduled an appointment, had to wait a week, but figured it was worth it, loyalty and all. I showed up for my appointment today, just before my registration is due, and was told "you didn't get the message, your appointment was cancelled"! What?? I said I had an appointment, did not get any cancellation message, and need to get my car smogged today, so the lady went to talk to the owner and he said OK, he would smog the car. I handed her the coupon, same as always, and was told sorry, we are not taking any coupons. No warning, no info when i made the appointment. etc. It would be almost $50, more than I have ever paid for a 15 minute smog check. Up against the wall, I said OK. He hooks up the car, I wait around, and 15-20 minutes later the girl comes and says my car did not pass, that it failed the evap test. I walk over to the car and check the gap cap, all OK, just like new and tight, then I talk to the owner, and he says the same thing, it failed, and the system said it was the gas cap. He also says the engine light was on. Now I filled the car up the previous day, drove a hundred or so miles, and the check engine light was not on when i drove into the lot 15 minutes earlier. So either this was an incredible coincidence that the system failed and the light came on just when I got there, or something else intentional happened. So now my car failed, and this is an Acura that never has had a single problem for the 14 years I have owned it, I had to pay this guy for the test, and now I have to drive it around for a few days before I can take a retest and pay him again. What a total rip off! I checked the system with my OBD reader when I got home, reset the error codes, and got a clean bill of health, all without making any changes. Figure it out for yourself, but the only possible answer is that this was intentional. read more

I have been to smog and go's in other parts of the state and this ranks near the top. The quote was accurate, I was in and out in 15-20 minutes, and the tech was very friendly. He also knew what he was doing. 35 bucks on my Toyota truck, that is a good deal. The place was a little hard to find but we all have mapquest. Also his girlfriend brought a plate of fresh home made muffins. mark alamo 4-25-13 read more

The employee managing the operation is not only fast and efficient, but is friendly and a great businessman. His work ethic is so strong, I thought he owned the business. He takes a personal, friendly interest in doing the best job possible. This is the best place I have ever visited, to get a smog check. I highly recommend this operation. R O Walker read more

Owner really knows how to run a successful business. Fast & reasonably priced. I would highly recommend.

I paid $80.95 for my smog inspection even though the coupon that I brought in showed that my smog inspection would only cost $44.20. I came in with a Smog N Dash Coupon which clearly states the smog inspection for my 1997 Toyota Camry would cost $44.20, ($35.95 for passenger cars older than 2000 plus $8.25 for the state smog certificate). So, I expected to pay $44.20. Unfortunately, they added a $20 Star Cars Fee, $15 Dyno Fee, and a $1.75 credit card transaction fee. So, I ended up paying $80.95 for the smog inspection, which was $36.75 higher than the price advertised online. I don't like to do business that way. read more

Smog n Dash truly does not care about customer satisfaction. I just got my Honda serviced with a new catalytic converter. The dealer neglected to tell me to drive over 100 miles before getting a smog. I drove 15 miles to Smog N Dash and my car failed. Their coupon said they match competitor's prices. I pointed out that most of the competitors offer a free retest. He said that matching prices only goes for the initial smog test. Yes, I should have made sure re-tests are free. However, if he says he matches prices he should mean it. I told him I would write a bad review....he said he didn't care. I think he was so mad at me that he parked my car as far away as possible for me to retrieve it after the retest. There were plenty of parking places at his business. He parked in somebody else's parking place that had a sign that parking was for that business only or it would be towed. Really. What a spiteful, disgusting man. I will NEVER go back there. For less than $5 more (with a coupon), Horizon Smog on Pacheco in Martinez offers free re-tests. 1 star is too good for the one I chose! read more

Had my car smog at Smog-n-dash today. Quick, efficient and friendly staff. Awesome experience!

I have showed Smog N Dash Coupon which clearly states the smog check would cost $26.95. Then I was told because my SMOG certification is required a STAR station they'll charge $20 more. Coupon clearly didn't say anything like that but I decided to stay anyway. As result my car didn't pass test and they said they will do retest for another $20. The next day I stopped to another Smog Check Stations and my car passed test with no problem. Make your choices, people, and be clever not to do business with Smog N Dash read more

Watch out for these guys. I will not take any vehicle here again, and I do not recommend using them unless you like feeling like you are being ripped off. First off, I was quoted $34.95 plus $8.25 on the phone so I decided to give them a shot even though they were not the most convenient place to me. I was told on the phone that $34.95 plus $8.25 certificate filing fee was the everyday price for any vehicle and that I did not need a coupon. I gave them my make and model and I asked twice because the vehicle is older and I know that most places charge more for older vehicles. I ended playing $90, twice what I was quoted on the phone. I had to bring back the vehicle because it had not been driven in a while since putting in a new battery. James told me that I needed to drive it for about 100 miles and bring it back and it should pass. On the second time back after driving the vehicle for 100 miles, it passed because the vehicle had to "reset itself" (according to James) so that meter readings could be taken since it had not been operated for a while. I was charged $50 on my first visit, and $30 to retest plus the $8.25 certification fee and $1.75 to pay with debit. So, I paid $90 when I took it there expecting to pay approximately $43.20 out the door based on what I was told initially on the phone. I'm just saying that I not real happy with these guys because they seem to have inconsistent pricing. For instance, the "internet/phone call pricing" is completely different from what they post on the wall of the shop and is also completely different from what they arbitrarily quote off the top of their head once you are in the shop. Note. I was originally quoted $59 out the door when I brought it in the first time. They charged me an extra $30 to retest after I already paid them $50 the day before when they said they could not take my meter readings because the car had not been driven. Most places retest for free if it does not pass the first time and I thought it was pretty lame of them to charge me and extra $30 for the retest because they could not get the meter readings they needed the first day. I felt ripped off. DON"T USE THESE GUYS. And, please, anyone from SMOG AND GO of Walnut Creek, don't respond with a lame apology/explanation/excuse about the bad experience I had here.....Own it, because you did it. SKETCHY PLACE...SCAMMY VIBE...ARBITRARY OVERCHARGING FOR SMOG TEST! BUYER BEWARE OF THIS PLACE! I PAID DOUBLE WHAT I WAS ORIGINALLY QUOTED!!!!!!!!! CON ARTISTS!!! read more

The smog inspection itself was done efficiently and the entire wait was only about 25 minutes. However, the marketing and pricing tactics these guys use are pretty sleazy. I found them using a Google map search and the "rollover" touts $15.95. When you go to their website it is $19.95 with a coupon. When I showed up the owner said $37.95. When I gave him the coupon he said "okay, but there are other fees" and the total came to $37.95. It is terrible that they can get away with such deceptive practices. It makes the customer feel like a real sucker. I'll never go back. read more

Poor customer service. Waited over an hour after being promised 15 min. Additional undisclosed cost (older car, dyno fees, credit card fees). Looks good when you have coupon, feels bad when you bay the invoice. Avoid at all cost! read more

Super quick and exactly what they advertised. A rare find these days. I was there when they opened, paid cash and was done less than 15 minutes later. read more

I got my car smog checked. The tech tells me "congrats, your car passed" charged me and handed me a bunch of papers. I asked him how long it takes to report into the DMV, and he said only a matter of hours. I wait days, and nothing, so I go into the DMV and they said nobody reported I passed a smog check. I look through the papers the guy sent me and sure enough, my car failed on one small thing that is easily fixed. So I call up the shop, and tell them what happened and the different guy on the phone accuses me of purposefully messing with my car computer to cause the problem, tells me he doesn't have time to talk or able to even look up the results of the test on his computer until I told him I had them right in front of my face and would happily read it off to him. Turns out the problem can simply be caused by minor repairs that reset the computer, not by me MESSING with my car. Finally he consented that they'd do a free re-test. Um, no thank you, so rude. Waste of time and money. read more

Completely ignored for 10 minutes straight. At one point, someone came into the office to do some paperwork and neglected to even make eye contact. I ended up just walking out because I don't have time for nonexistent customer service. read more

Scammers! Don't trust these guys with your car! they advertise $20, but you'll pay triple that. They charged me $60 then failed my car, said they didn't know why it failed, but if I paid them more they would "research the problem" read more

Got my car smogged and didn't pass at Smog and Dash. Took it a repair shop, got a new catalytic converter and that same place did a pretest, car passed with flying colors. Went back to Smog and Dash for $10 re-test, all emissions had spiked again and failed. They told me that whoever did the repair probably missed something. I asked how can that be. Went back to the guy who did the repair, he does another test and again passed with flying colors. Frustrated took it to another star smog place down the street, and they tell me that my computer has been reset, i have to wait or drive long distance before car can be tested. Long story short the repair mechanic called smog and dash, and they confessed to having reset my computer on car, which sets you up for your car failing, plus they even said that their smog testing machine was not working properly. Hello, how can they be performing tests if their equipment is inadequate. The repair mechanic told them to refund my money or I would report them to the BAR. Walked in today and got all my money back, so I can take it to get smog at a honest establishment! Each year, BAR negotiates more than $4 million in rework, refunds, and adjustments on behalf of consumers.

These guys are the best! Steve and Matt are both very professional and helpful. They also have a great customer service focused attitude. Very fair pricing and fast service. I was in and out in less than 20 minutes. I will definitely use them again. read more

Be careful. Wanted to charge $80 for a test only smog, which is by far the most expensive test only smog cost in the area. However, another reviewer stated he was charged only $57. Appears they will try to take advantage of you if you are a female. read more

James was awesome! Thanks for great service. Fast, friendly and excellent price. Would highly recommend!

Never expected to have a happy experience at a smog check, let alone pleasant, but was completely delighted yesterday when these guys completed our check quicker than estimated, prob cause we said we were hoping to finish a DMV transaction within the hour. They were obviously busy but I think because we (including my 6yr old) stuck around in their tiny waiting area, they made a real effort and we got to finish what we were hoping to before everything closed yesterday!! They are also the most affordable place we've seen around and very efficient and courteous. Note the place is waaaay in the back of the road, same driveway as the Pho noodle place. But now that we know where it is we're coming back here for all our smog checks! read more

Good place to get your smog check for as reasonable a price as you can find. Why? Because they accept competitor's coupons. You literally can't beat that. Got my car checked while I ate at Kevin's Noodle House (smog n dash is behind Kevin's Noodle House). When I finished eating the car was done. read more

Quick & relatively painless. Smog N Dash delivered thanks to Steve.

In and out of here in 10 minutes, smog passed and price was exactly what they quoted me over the phone. Totally happy & will definitely come here again. read more

Went here based on a Google search and it was great. Found it easily and even though they were busy, it took only a few minutes. James really hustles and he's nice and I hope he doesn't have heat stroke hustling in this heat. He's excellent! We'd come here again. read more
