Best and most honest car mechanic I ever dealt with. Wish I knew about him earlier. I needed a set of new tires, David found a deal with Costco that beat his prices, so he sent me there, saved me 60$. On other occasions he is detailed and honest about his work and prices. My family's cars get repaired only with him. read more

Okay so many of you know that DAVID from ENGINE DEPOT left. He started his new business and it is SMART AUTO. What can I say? Same great service with low prices just like before. David is always honest and will tell you straight up what you need and what you DON'T need. You will always be treated right and will always leave happy. I am very happy my go to mechanic is back with his new store front! Congrats to him, and I am very happy that my car will be taken care of my a honest and reliable meachnic. read more

Only pay for what you need. Treat you fairly. Always honest. Hard to find a better business person. David's policies are always consistent. Go here!!!!! read more

David was recommended to me by a friend and I have not found anyone more honest, helpful, and friendly in helping me maintain and repair my car. David and his team are responsive and quick and the quality of their work is top notch. David clearly explains everything he sees to you and even shows you photos! He lays out all your options and tells you exactly what he thinks for each one. David's prices are reasonable and fair. I drive an 12+ year old car which has been running great with no issues since I started going to David regularly. Even after moving into Chicago, I still go to David for all my car repair and maintenance. Highly recommend! read more

I've been in the search for an honest mechanic for the longest time and I know after I met David that my search is over. David is incredible, he goes beyond his duty to satisfy a costumer. Not only is my car in good hands but I also know I'm not being ripped off by anyone. Ever since I met David I haven't taken my car anywhere else, nor do I plan to. He's been great and and has taken the time to teach me how to care for my car as well. If you're in the search of someone to trust and give business to, David is the guy to go to. read more

Recently brought my Toyota Highlander in to fix a vacuum leak that I was having. Before I even handed my keys over David was already walking me through how he planned to diagnose and fix the issue. From the beginning I felt like my car was in good hands. If you're looking for an honest and knowledgeable mechanic at a very reasonable price point then I highly recommend smart auto! read more

Let's face it it's so difficult to find a decent honest mechanic who isn't out to squeeze as much money as possible. But then you have David Bang owner and mechanic who is trustworthy and honest. He doesn't push to get things fixed unless he would would do it himself. He is straightforward and explains the options well. I'm just sad that I don't live closer but am driving up from the Near West Side of Chicago just to get major fixes done here. Yes I'm driving from United Center area, paying two tolls to go in the suburbs because this guy is the real deal. Thanks David for all the years of service I recommend you to all my friends. read more

David is very honest person. He is not like other most of the mechanics who want to rip customers off. He is very experienced mechanic. Would advise him to have bigger shop and add tire services as well. read more

I trust David whenever anything goes wrong with my Mini. I had a horrible experience with another mechanic (had to get my car towed 3 times within a 2 week period)! That's when I found David and he was able to identify the issue, explain the problem to me, and fix it at an affordable cost (no more towing involved). He never tries to sell me anything that I don't need and is very straight forward. HIGHLY recommended. read more

David has come through again Axel broke, got me in first thing and had me back on the road that day. My family is now visiting smart auto also. Thank you David for your honest and spot on work! read more

probably been having david take care of my 2 civics for about 10 yrs or so and have sent a few friends his way. david is super honest and fair and doesn't do work that isn't needed. super great guy and a great business. i totally trust david with my car. it's a shame more mechanics aren't like this. honest, trustworthy mechanics are worth their weight in gold. david knows how much i rely on my car for work, so he always takes care of me and explains what needs to be done now and down the road. he won't ever do work that isn't necessary. read more

David is Really friendly and experienced. and people can get advice and service with affordable price. Highly recommended.

Smart Auto is a repair service YOU CAN TRUST! David, the friendly and down to earth owner, is not only a very professional, courteous and honest businessman he is also a well trained and highly experienced mechanic. After my Mazda 3 was damaged by one of thousands of Chicago's notorious pot-holes, my car needed a new lower control arm for my right front wheel. David patiently showed me parts prices and gave me repair options and worked with my schedule to perform the repair. My car now drives like new again!!! I am 100% satisfied!!! I can't say enough about how pleased I am with David's excellent service and professional friendly personality. My friends and family will continue to recommend anyone who needs auto care to go to Smart Auto. Make the smart choice. Choose SMART AUTO!!!! !!!! ( " )b Thank you David! All the best to you and your continued success!!!! read more

David is an honest and expert mechanic - what more could you ask for? Never tries to up-sell you anything and will give you a fair price. When I moved to the area a little over a year ago I asked a bunch of friends on Facebook who the best local mechanic was and his name was referenced repeatedly. Now I know why. When I complained of some vibrations in my car at higher speeds he took the time to get in the car with me so we could talk through it as we heard the noise together (who does that?). read more

I took my car somewhere else- BIG MISTAKE. Don't take your car elsewhere. David is passionate about cars and I have never met someone so knowledgeable and loves your car just as much as you do. We need more people like this guy!!! David and staff care for each car as their own. What an enthusiastic, reliable, caring man. Highly highly recommend. read more

I messaged through Yelp for a quote for a repair for a friend. He eventually took his vehicle here; I don't know the details but he was quite happy. He referred me here when I had some car problems. Turns out, my car problems we're mostly annoyances and not a risk at all, David assured me of this and said that they could fix it, but he wouldn't recommend it as it would be a waste of money; he could make the noise stop, but the noise wasn't hurting anything; at worst it was a slight annoyance. Additionally, they detected a faulty sensor, again, they could resolve it, but it wasn't critical. I had to go to emissions soon, so I was concerned about the sensor/dash light, but he explained that the ABS light was not a concern for emissions testing. David only charged me for my oil change, as I recall it was quite reasonable. I had to ditch my last mechanic because I believe he was pulling a fast one on me, my friends, and my family. Don't do business with shady mechanics. Take your vehicle somewhere that cares about doing the right thing! read more

David is honest, reasonable, and knows what he's doing. I have been going to him for all my car issues since finding him on Yelp. Once finding him they were closed for a little due to the pandemic. Me being impatient I took my car to a friend of a family to work on my car. I still regret it to this day not being patience. My car started to leak oil after a week taking it to this other mechanic. That is when I took it David. David was kind enough to take my car on the lift, clean it, and told me to come in the next day to see where the oil was coming from. He showed me the next day exactly where the oil was coming from. I ended up taking my car back to the other mechanic to have the work redone. But ever since then any issue with my cars I take it to David. I have complete confidence with David and his team and know they will get the work done correctly. read more

Just found Smart Auto reading Yelp. Top Notch. Quick, reasonable & will for sure go back. See David. read more

The most trustworthy mechanic I've ever had the pleasure of working with. David always gives honest feedback about your car when you bring it in for service. My car wouldn't start and I took it in for repair. I was told it could be an alternator issue and I just about cried because I know a dead alternator = $$$. Fortunately it was a dead sensor, so it was much cheaper, but he also checked my alternator just in case as well as the other sensor and battery. In the end, he suggested only replacing the sensor, which I did, and now my car is fine. David always tells you exactly what needs to be repaired or replaced and doesn't make unnecessary repairs just to get extra money. I also hadn't noticed my car had no gas when I brought it in, and he even put gas in my tank for me. I cannot recommend this shop enough. I'll be a loyal customer. read more

David is AWESOME. Efficient, reliable, honest, diligent, and fair. My car needed a repair far from home and good thing for Yelp, I was able to find this place. He definitely deserves the 5 star rating! Thank you very much for servicing my car! read more

One of the hardest things to find is a reliable and trustworthy mechanic. I have known the owner, David, for almost 5 years as a customer and could not write a more glowing review. I recommend all my friends and family to go see David. He is knowledgeable and HONEST. It is clear David has the best interest if the customer in mind and doesn't screw people over. He has saved me hundreds of dollars in repairs and helped me pass my state emmission test multiple times. He also takes great care of my mom and family. I will continue to go to David's shop as and will follow him wherever he goes. Thank u david! read more

This is a great place to bring your car. David is friendly, accommodating and honest. His prices are reasonable, and his work is top quality. He explained everything, was offered knowledgeable solutions. I would recommend to anyone. read more

David is very knowledgeable and very honest. I would highly recommend this place for you auto repairs.

Went there to have brake work done. They found the problem very quickly, and repaired as necessary. Skilled technician and. reasonable prices. read more

David has always been a trusted mechanic and great person with very fair prices. He is very honest with what needs to be done and never suggests anything unnecessary. I have had our cars serviced by him for 7 years now, even before he opened his own shop. I've recommended him to many of my friends and family, who are also now repeat customers. read more

The shop owner, David, is honest and is very knowledgeable which are traits hard to find in a mechanic. I can say a lot of other positive things but I think those two things are the best advice you hope to hear when you're looking for a place to fix your car. read more

David Bang has been my mechanic for exactly 6 years. I have been going to him since he was employed @ another mechanic on Golf & Arlington Heights Rd. I wouldn't trust my Jeep with anyone else. David always explains everything that needs immediate repair / replacement and let's me know which repairs I can hold off on. He is knowledgeable, his services are priced fairly and he is SO honest. He has replaced my brakes, replaced a serpentine belt, replaced my alternator, installed my battery, and replaced both the front and rear window lift plate regulators (my Jeep is old!!) and he does my oil changes, too. David is an automotive genius and I highly recommend him to everyone in the Northwest Suburbs. And FYI, he is the most cheerful, friendliest mechanic that you will ever have the pleasure of dealing with. I am so glad that I found him. His waiting area is teeny-tiny, but he offers his customers some dynamite Korean coffee!! Powerful stuff. Drink a free cup of coffee and scroll on your phone to pass the time, while the repairs are being made. Your car is in excellent hands with David Bang & Smart Auto. read more

Easily pass hundreds of repair shops on my 20 mile drive to Smart Auto from downtown, won't take my vehicle anywhere else and servicing my vehicle with David & his crew is worth every penny, as well as, peace of mind. Recommend calling in advance to discuss your vehicle concerns & coordinate the best day & time to visit, then they can best support your needs timely. I've saved a bunch going with Smart Auto and more importantly know my vehicle is taken care of professionally so I can zoom around safely on the road with less time in the shop. Thank you! read more

Recently got oxygen sensor replaced on my Corolla. Spend like $ 600. Waited for some time before posting this review. The check engine light is gone. So this issue is fixed. Happy about that. read more

Everything that's been said about David is true. Very knowledgable, honest and overall stand up guy. Will tell you up front what issues are and will provide his recommendations. I will be using his shop for all my car needs read more

Answers the phone or returns calls promptly. Got me in sooner and at a more reasonable cost than the other 5-star shops closer to me. Doesn't charge extra for reputation. Explains things thoroughly without condescension and has a plan for watching the iffy things (it's a 2003 vehicle). Worth going out of my way for and will continue to do so. read more

Found my new auto guy! David is super knowledgeable, friendly and honest! My oil change had a quick turnaround. I will now use Smart Auto for all my car needs. :) read more

I've been a satisfied customer of David's for a few years, since his days at Engine Depot. Always reliable, friendly, accomodating, knowledgeable, and most importantly, honest and fairly priced. Now that he started his new shop at Smart Auto, I'm happy to follow. It's rare these days to be able to trust your service people. At Smart Auto I know my cars are well taken care of, my schedule and budget are respected, and I'm only paying for the work that's needed. If you are looking for a good and fair car shop, run by a trustworthy professional, your search is over. read more

Used to go to Engine Depot because of David Bang, and now my business will follow to Smart Auto. Honest mechanic used to be an oxymoron, but David has restored my faith in the profession. He's the most honest, transparent and fair mechanic that I have ever been to. Need a new fuel pump on your car? David will patiently explain what happens if you don't replace it - what it will cost if you do replace it and he can find an aftermarket part - what it will cost if you use OEM -- can you do part of the work now and part later? He finds a way to get the work done for much lower than the competition, and I've never had any problems with the repairs. Can't recommend David highly enough! read more

Great work by David! Takes good care of his customers. I've been his customer for over seven years and I had nothing but good experience. I had my own crv with bad power steering axle and he replaced it at reasonable cost. Now I have a forester and he fixed my air conditioner. I do the recommended maintenance through him as well and he makes sure he checks everything throughly each time. You get more bang for your buck since he does high quality work. read more

David is an angel sent from the sky, after he fixed my car he drove himself to the emission testing station and pass it. Who would do that?!! read more

I've had David as my mechanic for years and when he moved here we followed (and even people we've referred to David before followed as well). We take our cars here even though it's a little out of the way now. They fix what needs fixing and they tell you what to expect in the near term as well so that you can plan accordingly. I've taken my car here more than once only to be turned away because there wasn't an issue (or it was something that needed a quick adjustment). It's actually a feel good experience even though no one likes spending money on auto repairs. David's gone out of his way to offer the best experience and service. read more

Thank goodness for good people like David. We had our car towed to this shop, after taking it to a another shop that claimed to have run a full check yet somehow our power steering went out. Same day car gets towed to him he gave me a call to let me know it was something as simple as the alternator. David had access to alternator in nearby warehouse and was able to get my car repaired day of and even changed my oil because he noticed we only had about a hundred miles left on it. Then he stayed late because we were stuck in horrible traffic to pick up our car and was so kind about it . That is going above and beyond in any case and we're so grateful and so appreciative. read more

We have had David work on our cars for many years. He is a great guy and without a doubt the most honest mechanic you will find! The needle on our speedometer stopped working yesterday. My husband called and talked to David and we were able to bring it in mid afternoon. David explained the possibility of what might be wrong and what the cost would be. We received a call at 5:30 letting us know that it was done. It turned out to be something easy to fix and we were only charged a nominal diagnostic fee. Congrats on your new shop David!!! read more

I knew David from Engine Depot. He has been my mechanic for both my cars for almost 8 years now and he is by far the most honest mechanic I have ever met. I am at a point where I do not need to discuss prices because I am sure that he will fix what needs to be fixed and he will not charge more than he has to. His Dad, John is pretty good guy too, he recently replaced rotors and brake pads and did a very satisfactory job. I have referred many of my friends and colleagues and they all are now a regular customers of smart auto. Keep up the good work my friend ! read more
