Brought 2 cars in and had both serviced and priced at a good deal. They don't use any after market parts only straight dealership parts so you're getting the best quality for your car. Vinny is a great guy and was recommended to me from another mechanic. If another mechanic is recommending you to Vinny just know they're doing something right! I'm coming back here and only here. Thank you again Vinny and D V smog pros! read more

Super honest and very helpful. Highly recommend this place, all my family and friends that I recommended have trusted Vinny. read more

D V Smog Pros - Smog Check Stations Near Me - Walnut, California

I stopped by Friday afternoon for a smog check. The staff were friendly and I was in and out in 15 minutes. The price is the same as others in the area. The lot is small but there's street parking around the corner if you want to check in before bringing your car around (that's what I did). Plus the waiting area has a nicely kept fish tank. Very satisfied with how it went and will come again. read more

I called a few smog check places and this one is very close by and they told me that it's $38 for smog check with certificate! Some places charge $50 or more for smog check so I would say this is the best deal in the neighborhood. I got there when they opened at 9 and they took less than 20 mins to get the job done! easy peasy! FYI: there's a small fee if you pay by credit card. I didn't know coz they didn't tell me but it's no big deal. It's close to $40 total. I would go back if my car needs smog check again. read more

Quick, efficient. People friendly environment. Great bedside manners. Mr Vinny Is the most honorable, compassionate and intelligent mechanic I know . There hasn't been a question or a Repair that him or his staff at his shop could not repair. As of yet, of course I have four cars all of which he has worked on when I mentioned he it also includes his staff and have never had to take anything back, even though the option was presented and available as he stated . Also to mention that he has such integrity and honor in his work that he does that they even wash the car before he calls me and tells me it's ready. For somebody to go the extra mile these days is a rare find God bless you, Mr Vinny and your whole crew May God always shine his light upon you ! read more

Vinny was a great help. Brought my car in because of the catalyst monitor shows that it is not ready. Will not pass smog. Drove it myself trying the drive cycles mentioned on the internet still no use. Brought it to Vinny and he got it monitor ready and passed the smog for me. It saved me a lot of time and trouble. Very efficient. Strongly recommend if smog didn't pass, let them handle it. read more

As you can tell from the rest of the comments, Vinny is a trustworthy mechanic. I've been coming here for decades and refuse to find another mechanic even though I have since moved away. He's not one to tell you to tell you to do nonsensical repairs. His team that works with him are also outstanding! I've taken older cars (89' e30) and newer cars and his expertise in diagnosis and recommendations truly shine. He's patient, honest, and knowledgeable. DV Smog Pros is a local family establishment that I will continue to support and recommend to friends and family! read more

I called 3-4 smog check places in the area and places ranged from $45 to $60. I used to get smog checks done at whatever place my dad has been going to without second thought, but after reading some bad reviews of the place I had been going to for the past few years, I decided to take to Yelp. Lesson learned: definitely price shop for a smog test, because all it is is a measurement hose being attached to your car to read smog/emissions levels. Nothing fancy is done, and the job is a quick one. It should NOT cost as much as $60...ridiculous. D V Smog Pros charges a total of $38.20, which is significantly lower than competitors in the area. Mind you, this price INCLUDES the cost of the STAR certificate. Most other shops start at like $35 for just the smog test itself and charge $10 for the certificate. The service was quick too -- I was there for like 10 minutes probably (I went on a weekday morning though). Will be back here and recommend this place to people in the area. read more

We have been bring our cars to D V Smog for at least 20 plus years, and words cannot describe how much we are satisfied with Vinny and his team. We have had BMWs, Mercedes, Mazda, Kio, Corvettes, and my current Tesla and Vinny has worked on ALL of them, including replacing the Bushing Arm on the Tesla. They are an amazing team of professionals, always pleasant and they will go out of their way to make sure your vehicle is serviced in a timely manner. Their prices are excellent competitive but should be more because of their quality of work. Prior to meeting Vinny and his team we would go to mechanics every where, argue, fuss, fight, continue to bring the cars back because of bad service. read more

I failed my smog check at a test only location due to a non responding sensor. Took it to my regular mechanic & they confirmed a slow responding sensor. Came to DV Smog Pros to get it fixed. Vinny checked it out & said it would pass smog now, that the sensor was responding. Went back to the test only place to re-test & it passed, no problems. Thanks Vinny for being honest & not trying to do work that was not needed! It's great to find an honest repair shop! read more

As long as Vinny remains the owner, I'd highly recommend to anyone. read more

Very good service and honest with their customers. Thanks DV Smog Pros .will be back next time!

Five years ago, I was looking for an honest repair shop and was referred to DV Smog Pros. Vinny, the owner, does not try to get you to buy additional repairs by using scare tactics, like I've encountered at other shops. Fair prices and my minivan is always ready when they promise. Vinny has properly diagnosed (the first time I asked) about some repairs that the Dodge dealer said they couldn't find anything wrong (of course it was under warranty and the Dodge dealer just didn't want to do the repairs) My daughter has been taking their Lexus there for the past year and is very pleased too. Highly recommend! read more

Great service by Vinny. Fast, honest, friendly, and competent. Highly recommend for anyone looking to get a Smog Check.

Service and prices are great. Very professional mechanics. Different family members recommended them to me and now I see why

They did smog check for my car very fast and it's cheap than the other store. I recommended this store for everyone.

Expensive smog check. They gave me a quote of $52.99. Instead, I went to a nearby smog check station and got it done for $30.

Best, most reliable and well trusted shop you can take your car to get fixed. Honest people who do a quality job. Have been taking all my cars to Vinny for 10 plus years and have never had a problem! Thanks guys for caring about your consumers. read more

This guy Vinh is not to be trusted. Gave diagnosis on repairs needed to pass smog and one; price was outrageous, two; took car to another more trusted shop and they discovered repairs needed were not of what was diagnosed by Vinh. He not only will reimburse for the misdiagnosis but there is no flexibility whatsoever on his price and won't even waive the diagnosis fee if we had done the work at his shop. This is so customary in all shops and he wouldn't even offer this, which is why I took the car down the street in the first place. read more

Vinny is one if the most honest mechanics around. He fixes only what needs repairing. I've been going to him for 4 years and have no complaints. He and his crew are honest, hardworking guys. read more

This is not about their workmanship since I didn't let them work on the car. This is more about thier price and maybe ethic and honesty. Wife took her mom's car in after it failed smog check, and received state $500 voucher for low income subsidy. Wife's language skill is not the best, but I sure hope that was not the reason DV tried to take advantage of people. DV Smog quoted her $1800 to repair "Smog Check Failure" related issues, so her out of pocket will be $1300 after State $500 voucher. I declined his service after I talked to him(Vinny, I think). I contacted another CA DMV listed approved smog repair shop (Mobile in Diamond Bar) for my in-law, and explain my situation, and he said $500 voucher should cover the cost of the repair with a co-pay of $130. 3 hours later, car was fixed, and passed Smog Check. If you go DV to do repair work, make sure you know what you are doing. Do you due dilligent research. read more
