They are very thorough in explaining the situation and what it will take to remedy it. Competitive pricing. Great customer service. State of the art diagnostic equipment.

Took my car here after the VW dealer tried to charge me $1,000 for something that Quantum found was not even the problem! Since I first spoke to them on the phone they were super kind and took the time to talk with me through everything. Will definitely be coming back for my future car needs.

I've gone to Quantum Mechanics for over two years and have sung their praises because they have always provided excellent service. I tried scheduling an appointment a week ago but was told I could not wait on my car. This was not for major work. Waiting was never a problem until this past December. Their new policy takes no consideration into the inconvenience to loyal customers. When off I usually have several errands to run. It is very poor customer service to have a "waiting room" and REFUSE to let customers use it! With hours ending at "5:00 pm" and only open Monday-Friday you make customers pay extra money to rent cars or use Uber. I rented a car last December due to an extremely busy day with a Trunk Show that evening. After having to rent a VAN I get home, start getting ready for my show and in less than 3 hours after getting the rental they call.... my car is ready. The manager at Enterprise was kind enough not to charge for the rental car due to the short time but that was luck. The amount of unnecessary STRESS ruined the entire event. I have NEVER known a business WITH A WAITING ROOM REFUSE TO LET CUSTOMERS USE IT! This is the only place I've taken my car since moving here and I find it very sad to know I either have to start over looking for new mechanics or rent a car and add that to the cost of any repair.

These guys are rad. I came in since my '05 4Runner had a loud squealing noise coming from the engine for the last few weeks and I assumed it was going to be another expensive fix. They discovered it was a power steering bottle that was left under the oil filter drain (!) that was placed there during the last oil service and forgotten at Savannah Toyota - which is where I would usually go to have my car serviced. They ended up not charging me for the service inspection and the removal of the bottle! The customer service was second-to-none (thanks, Ally and Tim!) and they didn't hesitate to walk me through everything. I just moved up to the Atlanta area and I'm glad I found these guys - I'm coming here to get my car routinely serviced from now on.

They were expecting me as scheduled, understood my concerns, and did the work efficiently and effectively. In addition, they accommodated me with rides to and from the MARTA station so I could leave my car with them, and they carefully explained their recommendations for service both that day and in the future. I will DEFINITELY be a repeat customer.

QM Auto has been my go to mechanic for over a decade. They've always gone above and beyond to make sure my vehicles, and family are taken care of and traveling safe. I'm very fortunate that I've never had to worry about quality car maintenance. Its nice to know you can trust your mechanic both in an informative and hands on capacity.

You guys did an amazing job fixing my husbands BMW X5. We had just moved here and of coarse something would happen to one of our vheicles. We had our vehicle towed to Quantum and they took great care of the car. Alli would call us with updates and walk us through what was going on and what the options were. Very honest. No pressure or trying to get money out of you just because. We will definitely be bringing our vehicle back to them when it comes time for service and maintenance. Thank you Alli and thank you Quantum.

This was my first time visiting Quantum Mechanics. I felt respected and comfortable here. The shop is very professional and frankly the cleanest auto shop I have ever visited. I still do not trust mechanics but on the sliding scale, I trust this place more than others.

They are always friendly and take the time to explain what repairs they would like to do. I appreciate how up front they are with pricing and their advice on when to wait for repairs as well.

These guys are professionals. By that I mean that they do solid work, at reasonable prices, they communicate clearly and are friendly. I dealt primarily with Spencer and they made it easy for me to drop off, pay and pick up my car on my schedule. I'm a fan.

In and out quickly and positive marks all around. These guys are serious professionals and the atmosphere is very genuine and facilities are quite nice. They give you an honest answer and let you decide on what needs to be done with absolutely no hassle. I will only go here from now on.

As always, we received top-notch service from the QM team, starting with ease of scheduling, through diagnostic and cost transparency and finally to the timely return of our car. We've always found them be honest in their assessments and willing to work with us on determining the best solutions for our needs. It's great to have this much confidence in one's mechanic and to be able to recommend them wholeheartedly.

I've taken my Toyota Yaris here twice, and I can't recommend this place enough. They are honest and friendly, and I'd recommend them to anyone with a foreign car. With Quantum Mechanics, it's been very easy to keep my 10 year old on the road.

I own my first Mercedes Benz and I knew when I purchased it, it would be costly to maintain. Because the car is foreign and I am over protective of my car, I only wanted specialist to handle my car needs. So when I found this place I was super excited. They are truly specialist in foreign cars and know a lot about a lot. However, I think they take advantage of that and charge wayyyyy too much for nothing. If you go to them, prepare to pay a ridiculous price for simple fixes simply because your car is foreign. You could easily go to any other well respected car shop and pay half the price for the same issues. I'm only speaking from experience. Unless you're rich and can afford to pay whatever they ask, then I would recommend going elsewhere.

Best auto repair shop in Atlanta! Period! I had an ABS unit failure in my BMW with a projected cost to fix by the BMW dealership and 3 other premium repair shops in Alpharetta area for 3.5K +. No one offered to get it repaired. They only offered a replacement. Quantum Mechanics folks shipped the part out for repair and backed/warranted their work for 3 years! They didn't even charge me for diagnosis. All the other guys charged me 100 bucks plus for diagnostics! Quantum Mechanics customer service is the best I have seen for this class of business. Found them through a sponsorship they did on NPR. I paid less than a 1000 bucks to get the ABS unit working perfectly.

Terrific customer service with clear and accurate diagnosis. I received frequent updates on diagnostics, parts, and pricing. Would recommend Quantum to anyone and will be a return customer, but hopefully not too soon.

I wanted to share publicly my experience with "Quantum Mechanics" of Decatur Georgia who recently repaired & serviced my vehicle. When I think about these guys there are 3 things that immediately come to mind... "Exceptional Treatment, Honesty & Customer Service!!" They were so detailed with the information that they gave me about my sixteen year old 2001 BMW 530i. They went out of their way to answer the many questions I had. When my automobile was returned to me the repairs had been done correctly and the car was as clean as when I brought it in. I Trust Them!! How often can you say that these days? I'd recommend them highly to anyone.. BH (Atlanta Georgia)

I'm a longtime customer of Quantum Mechanics. Honda and Lexus. They handle all my new vehicle warranty checkups and work as well as tires and all maintenance. The staff are knowledgable, trustworthy, reliable, efficient, clean...I can't say enough! I will NEVER go back to a dealer for servicing, ever.

I’m very particular about who I trust to work on my car; I’ve been in Atlanta for a year and only recently stopped driving down to my long time mechanic in Florida because I finally found a shop I trust here - Quantum Mechanics. The mechanic completed a comprehensive, detail oriented inspection of my entire vehicle. Then Spencer called and communicated the mechanic’s findings and the recommended maintenance in a clear, knowledgable, and professional manner. I’m absolutely confident nothing will go wrong with my car because of neglect or oversight on their part, nor will they oversell me on unnecessary repairs. For something as valuable and important to me as my vehicle, it’s not worth using a cut rate service to save a few bucks upfront because shoddy workmanship (or worse, dishonesty) always ends up costing more in the long run. An excellent and trustworthy mechanic is priceless, and Quantum is the best.

I've been going to Quantum Mechanics for 7 years and have always had a great experience. Most recently, I have called upon Matt Swaim who is very knowledgeable, efficient and friendly. And the shop is impeccable. I highly recommend Quantum Mechanics!

These guys are great! Matt Swaim assured me they could work me in for an oil change and tire rotation on my 2016 Honda. I swung by and dropped the keys with Spencer, and before I knew it, they had called to say it was ready. QM checked the entire car over while it was there. Top notch!

I had recently purchased a used car, so I decided to bring it in to Quantum for a checkup, having heard of the shop from friends. After the inspection, the shop's representative, Spencer Tondreau, called and informed me of all the potential work that needs to be done, which are: a battery replacement, belt replacement, and changing the air filter. After doing some research online, I elected to forgo the air filter service to do it myself, and was met with no pushback or opposition - being a salesman in my previous job, I appreciated that. I did get the battery and belt changed, and the car was finished and returned to me by the end of the day. Overall, my experience with Quantum was very positive. I was assured that the people working on my car knew what they were doing, and I had the peace of mind knowing that I wasn't being charged for extra service I didn't need. There's not much else you can ask of your mechanics.

I've been going to Quantum since I got my Highlander a few years back and I can't express how great the service is. Working with Spencer is smooth and painless. He is very knowledgeable of what goes on in the shop and does a great job giving you the information needed in a timely manner so that you know what to expect. The facility is great and am never disappointed after get my car back.

I have been bringing my cars here for the last few years, and every experience I have is better than the last. The team is always very professional from the first point of contact, scheduling, and all the way through the work getting done. The waiting room and shop is the cleanest you will ever see, too, and that is the icing on the cake. White glove treatment all around. I can't say enough great things about Quantum Mechanics.
