In addition to great car service, I want to highlight how Mrs. Mercy and her team have been, not only, friendly but made me feel like I was dealing with my own family-loving, kind, and patient enough to explain issues and my options. As a (metro) Atlanta transplant, I have struggled to find a local mechanic for an older model Toyota. I stumbled upon M&M via google, saw the high reviews and that it is Black-owned so decided to give them a try. My first point of contact was with Mrs. Mercy who, very politely and efficiently, invited me to come by to get the problem diagnosed. Upon arrival, I received a bottle of water. Within minutes, they took my car, assessed the problem and gave me a very reasonable quote without a bunch of random line items. Only because two parts needed to be ordered did I need to come back a different day. The part arrived quickly, they let me know it arrived and when I could come back. They promised to be finished within a certain, quick, time frame. I brought my mobile wifi and laptop then worked in the few chairs they have within the shop-all while I waited. They fixed it within the time frame and my car is running better than she has before. ;) This is a neighborhood-friendly shop, welcoming and you can tell my the flow of customers, trusted. Consider them for your next repair and tell them Jonica sent ya!

Jerry Jr slammed into my car on the highway a few years ago and begged me not to call the police because (among other reasons…ask your son about that one) he didn’t want to involve his insurance. He said that his family owns M&M Muffler and that he’s a manager there. He said M&M Muffler would make sure my car was put back in the same position it was before he wrecked my bumper, since I was generous (and gullible) enough to do this without insurance. Behind the name of M&M Muffler, Jerry Jr. dishonestly dragged me along for a full YEAR (literally a year), lying about ordering my bumper, then having my bumper but needing the right paint to be ordered (white paint, nothing complicated), and so on. I was patient with him the whole time, even when it was becoming more and more clear that this is a dishonest person and a dishonest company. Eventually, he told me that I should’ve called the police and there’s nothing that I can do about that. This was a huge letdown and I really battled with whether I should write this. But the fact is, he used M&M Muffler and being a manager there as credibility, and M&M Muffler was fully involved with this SCAM. I wouldn’t trust this shop for a second, and anyone who does will learn the hard way not to a second time.

This place is a life saver! I broke down in the middle of the street a couple of times. An AutoZone associate referenced me to come here. The associates of M&M came to AutoZone to review my car and advised of the issue. Once getting my battery charged at AutoZone, I made my way to their shop. Mercy and her crew are amazing. They took care of me even though they were swamped with customers. They made me feel like family and took very great care of my car. Thank you Mercy and crew for being awesome! I'll be referring you to anyone who wants excellent car care, professionalism and southern hospitality!

M&M Muffler is not in the nicest part of the city nor is it the cleanest auto body shop I've been in but the owner and staff were honest, respectful, and timely. I called in the morning, the owner asked me to come by, she lifted my car and told me the problem within 5 minutes of my arrival. She gave me 2 options and told me which one she would do if it was her car, which wasn't the most expensive option, and I was back on the road within the hour. I would highly recommend, just know that it looks like a junk yard and the waiting room is the parking lot.

Ms. Mercey and her team were amazing from start to finish. Getting my car serviced is my least favorite task - I’d rather get a tooth filled or have a home repair done - so I had put off my repair for a few months. She saw my car an hour after I called and had it done the next day. They have great communication and never left me guessing as to my car’s status. No trying to push extra repairs on me - she listened to me and fixed the problem. Very reasonable prices and they take card! Definitely my new go-to auto shop in Atlanta.

Once you explain too them what you experienced in with your car they do a diagnostic test once it's completed it's plain to see the results you decide what you want repaired they can order the part are you can pick up the part before they get started they let you know the total cost of the repair work I take my vehicle and most of my friends vehicles and the work is always satisfactory also you don't know how long it's going to take to do the job and when you can pick up the car sometimes same day

Well that was just the craziest phone call ever. I have a car and the two mechanic's ive had work on it (family friends) cant figure out why it wont crank after a timing belt and waterpump replacement. I call a shop...THIS shop only to be told they wouldn't do work on it...not even provide diagnostic. ...well how the heck am I supposed to have it repaired if the shop wont even take a look at it? Bad frigging business. ..my money is just as good as everyone else's ma'am.

Mercy is a beautiful person, her professionalism is excellent, she repaired my car in the same day with no problems, compared to other automotive shops, that make you wait 2-3 days for a simple repair. My car was running like new once she finished and she also made me aware of some others things, she could repair. The service was great! Mercy and her crew will be the only automotive shop that will service my cars moving forward!!!

God I thank you for this shop! The most amazing people I’ve ever encountered, I came in with my car driving terribly. Mercy was patient and thoroughly checked all my spark plugs and coil packs. We found that they needed to be replaced. She replaced them and my car is driving like new. She didn’t overcharge me and she was transparent about everything I needed! I have found my cars home!!

Great customer service! I never review places, but this was so good that I had to. Went in because my tailpipe support rod snapped and they got me in and out in less than a half hour. They were straightforward and upfront about everything including how long the repair would take and what it would cost. Not that far from downtown, if you need a repair, then I highly recommend it!

I've only been here once and there wasn't anything super complicated going on, but Mercy gave me great service at a price that I think I'd have trouble matching elsewhere, never mind beating. She noticed that I walked home after dropping off my car with her....and actually came and picked me up when my car was done. Like...what?? Who does that? A+ for Mercy and crew.

Saved a lot of money previous mechanics in my area quoted higher prices and gave a different diagnosis surprisingly this female mechanic repaired my car with a fraction of the cost and she had a totally different diagnosis ...my car has not ran this well in YEARS I plan to take my car back for repairs and refer others Thank you !!!

Today was my very first visit and I must say I was very impressed. Not only are the friendly you feel like you’re amongst family. The part I needed that actually had in stock! They fixed my car promptly and at a fair price! I will most definitely be back and I’ll spread the word! Thanks for everything Junior …

I was able to get my car's spark plugs checked and replaced quickly. I left my car there and walked to a food truck lot...sat down and ate a quick snack... Walked back to M&M's and picked up my car. I like Ms. Mercy...a woman mechanic!!!!!... who's reputation precedes her. She Is an excellent mechanic. The price was right also!!

Have been to Thai location a couple time since I’ve been living in Ga . Found this place on a humble in like 2012 . They about the business they very honest they professional work in a timely manner. Good vibes every time I have to go to . I love it here even tho I hate to come lol . But over all great 15/10 always !!!

The absolute best muffler shop. She is a female mechanic and knows her stuff. I visited 2 other mechanic shops prior to her and I am so glad I went with her. She is professional, fair and did great work on my muffler Hands down the best . I made an appt she was able to get car repaired same day with in a few hours

Ms. Mercey is very friendly and knowledgeable. She explains the importance of staying on schedule with your vehicle maintenance. The staff is very professional and helpful. They provide quality service to all of their customers. Thank you for being a staple in Atlanta M&M Mufflers Automotive Repair.

I want to Thank Mercy and JR for being professional great mechanics. Their service is wonderful and I’m glad a good of friend of mine referred me to their shop. They replaced and fixed my break pads in less than 15 mins. They are a great family car service company! Thank you all!

Jr. & the family provided great customer service and got us in and out! He took care of our issue and also made us feel at home. We were sent here by another mechanic and we are truly thankful for them. We will definitely be going back for any other mechanical needs! …

The people here is awesome and amazing! They are very kind and very responsible. The starter of my car was broken, then my car was towed here to fixed. Mercy and her workmates gave my car a very good service and gave me a very good price. I appreciate for their service.

super quick/available, brought my car same day i called, they immediately started working on replacing piping around my muffler and were done in under two hours. Extremely nice, hardworking, efficient work and VERY fair pricing! Up front, good people. will come back!

Was charged only $20 for diagnosis and work on my truck! Mechanic Jerry Matthews even did some free welding and engineered his own solution when it turns out the exhaust manifold couldn't be fixed without spending hundreds. Highly recommend these folks.

Honesty is the best policy. And I feel like that’s their policy. I feel very comfortable taking my vehicle here. Fair price good service. Tell them Bryan sent you :-) ( don’t mind the pictures. I just added some random ones that I thought I liked.

Mercy was very reasonable. I used them 3 times to fix a few problems on my car. They were very fair with price and were able to fix it the same day.i use them when e ver i have an expensive problem to get a better rate and great service.

Mercy and her family are lifesavers. My sister's alternator died Labor Day, not only were they open but they got her fixed in under 3 hours. This is a good family owned business. I will be supporting them for the foreseeable future!

Professional, high quality, friendly, very economically competitive & honest service. I come here for all relevant service that has included emissions testing, electrical system issue, and some-time-soon, shock/strut replacement.

Had to call my main man Matthew he owns the place to get a tow to the shop to get my truck repaired bring cash$$$ they don't take credit cards cash app or zelle or anything like that, that's the only area they need to improve on

Mercy and the guys were extremely helpful with replacing my radiator. I will actually be returning in two weeks to get my wheel bearing worked on. I like the way they do business and will be using them for my future needs. A+

Came in to have exhaust pipe fixed and they made me feel like family I don't care how far I have to drive I am sticking with this shop. Shout out to uncle Junior ✊. And the prices are perfect!!! Thanks M&M …

Fast accurate and courtesy at its finest... Jerry and Mercey is running a Nice ship... My car is running so quietly that I forget it's turned on. So enjoy you are better working car. Today!!! Tell him Debbie sent you....

Mercy was absolutely amazing, she was able to get me in and working with my work schedule. They were also very quick at getting the repair completed! I would highly recommend Mercy to anyone looking for a great mechanic

They are so honest....and the price that they give you is honest & fair...I've went to them twice to have my car fixed and they done amazing work...if you looking for a good and I do mean very good auto place come here

The thing I like so much about this place is the quick, friendly service. I needed to have state-mandated emissions testing done for a minivan, and the folks at M&M Muffler had me in - and out - in about ten minutes.

The service is always professional and friendly, it's a family business with great customers service. Every time I go to get my car service they're all ways great! I would like to say Thank you!! Good luck #.

Mercy, is a beautiful lady. This lady knows her cars. I was advised by another female to take my car to this location, because the owner is wonderful, patient and great at what she does. That was the truth.

The family here always takes care of any car issue I have. I appreciate their honesty and the reasonable cost for repairs. They are experts and I would not take my vehicles to any other shop.

The owner is very knowledgeable and the staff is very friendly and helpful. They explain to their customers what is happening with their vehicle in a way that the customer will understand.

Absolutely recommend. They don't break your pockets and everyone there is customer service forward. The work they did on my muffler was pristine. No going anywhere else for my auto needs.

Mercy did a great job on my emissions inspection and got me out of there fast! Which was a shame because we had a great chat. Definitely going back whenever I need to service my cars.

Mercey Matthews is a genius. Super nice, and knows cars. I never hesitate to drop my car off with her knowing that it will be fixed right the first time, quickly, and at a fair price.

I came here for the first time this week. Jr. was able to help me diagnose what was wrong with my car and get me in and out in a timely manner. I’m definitely going back!

Ms. Mercy is amazing! Awesome experience every time I’ve come M&M. Reasonable prices and fast service. I won’t be taking my car anywhere else. Thank you for everything.

This is an excellent auto shop. The staff was extremely helpful and fixed my car perfectly. Their customer service is A1. The female worker was extremely helpful.

Couldn't be a nicer place to bring your car for a simple emissions check to a complicated repair. Everyone there is very happy to help. Trustworthy business.

Great customer service! I called last minute to get my alternator fixed and she was helpful and transparent about pricing. Will definitely be going back.

Junior is awesome!! May have a little wait, but the customer service and service he provides it is not matched by any other mechanic shop I've been too!!

I am a fan of the atmosphere and fast turn around. It has that personal feel. So when ever I go here, I feel secure my need will be taken care of.

Very nice folks and super quick service. 18 dollars for state emissions testing. Will come again next year for the test again. No line. No tricks.

It's so hard to find a mechanic you are comfortable with. Mercy is really great and makes you feel comfortable. I'm so happy to have found them!

Very nice staff and the mechanic is nice. Pricing is spectacular and more reasonable than other places. All my repairs go through this shop!

Good service! Got my brakes done by them a while ago and they fixed a noise my car was making. Friendly and well run, plan to be back!

Owner is great and has helped my family out a lot with our cars. Highly recommend her business to anyone who needs help on their car.

Jerry is very nice and helpful. I didn't have to wait a long time and I would definitely recommend this place as well as go back.

Mercy was extremely helpful and knew exactly what my car needed. Thanks from Starr and KK. …
