Honest old school shop. Very few honest places out there but this is definitely one of them. Hard working crew. Very helpful. Went in for exhaust repair. Turns out it was engine issue. Shop could have easily charged me for exhaust repair and diagnosis but they were honest and did not make unnecessary repairs or charges. Would definitely recommend these guys.

Phil does great work and is as honest as the day is long. He explains everything he will do in great detail, and he also explains what he will NOT do, and why. He actually talked me out of having some work done that the dealership strongly suggested must be done soon and he showed me why it was not necessary right now. He will not take your money for the sake of taking your money and his rates are much lower than the highly inflated dealership rates. I cannot recommend ATM Automotive any more strongly. I would give 6 stars if I could.

ATM Automotive recently underwent a name change to Waldorf Muffler & Suspension - FYI. I was looking for a reliable & quick car repair in the Waldorf area today & found this place which had very good reviews. I took my car in at about 3:30pm this afternoon due to a grinding and shaking when using my brakes. I was aware the shop would close at 5pm and was prepared to leave my car overnight and come get it the next day (and if I had taken my car to any other repair shop - I am almost positive this would have been the case). To my surprise, the mechanic on duty was able to do a quick diagnostic of my brakes/rotors/calipers, ordered the parts needed very quickly, and told me they should be done with my car before closing - same day! I sat in the air conditioned waiting room and he periodically came in to show me the degraded parts from my car to explain the issues I was having. I had a nice conversation with Brittany, the front desk attendant, and she also gave me periodic updates on the status of my car once they were on a roll. Before I knew it, my car was serviced and I was ready to go - at 4:45pm on the DOT (literally 1 hour and 15 minutes later). This experience was hands down the quickest, most efficient, friendliest, and most reasonably priced car repair I have ever been through. Especially for having just walked in about an hour and a half before closing! I highly recommend this establishment to anyone looking for a quick & affordable quality car repair. Thanks so much to Waldorf Muffler & Suspension!

Major Respect! Just the right amount of professionalism... I came to the shop on short notice... The guys knocked it out with no hesitation... The guys here gained my interest quickly. They’ve just gained a loyal customer. Also the prices are very reasonable.... Not cheap! Reasonable!

I recently had my catalytic converter changed by ATM. I checked the installation price from several mechanics offering the same services. I purchased the parts and it was installed with no problem. ATM took the time to explain their diagnosis before, during and after installation. Also ATM has great prices.

These guys are amazing! Been working on my car for a few years and have always taken the time to explain issues they see coming and anything they see that needs to be fixed. It’s always nice to feel comfortable with the people fixing your car and this shop is wonderful! I would recommend them in a heartbeat.

I cant say I recommend them enough (and sorry for the delay on a review, Phillip). I got my windows tinted by Supreme Tint, just around the corner from ATM, and I saw a small flyer for them (ATM). I had been wanting my exhaust done on my 14 Dodge Ram, so I jumped in to get a quick quote. Not only were they friendly, which is always a huge plus to me, he was explanatory when needed. I think I took it in the very next day (maybe two days after), because Phillip said he could get it done early and quick. I dropped my truck off around 10:30, and I got a call by 1:00 saying it was done. It was quick, correct, and very well priced. I definitely will be going to them in the future (likely sooner than later because my damn wheel is squeaking, so I think my bushings are fried >:(Thanks, ATM.

I was calling around looking for a mechanic. I felt very comfortable with Phil from the 1st call and have not been disappointed. He is very honest about what needs to be done, very efficient and timely. Always in and out same day. Very reasonably priced. Good honest work. Much needed in a mechanic. I refer everyone i know to him

Phil did a great job on the exhaust for my superbee Charger, he explains information to make you understand, as many of us are inexperience Customers to the car repair world. He is very professional and the work is great quality. I would recommend this shop and will return for future work

Phillip was recommended to me from a friend who raved about his work ethics as well as his honesty towards his customers. He gives you recommendations on what he thinks is best for your vehicle. I took my Lexus LC 500 to get exhaust work done to it to make it louder and I don’t think I could be more satisfied than I already am. He charged me less than other shops I got a quote from and he did it with a smile. Overall, the modification came out superb. I highly agree and would refer all my friends that needs help with their piping/muffler/resonator/exhaust system kits. Excellent service, Thank you!

My exhaust pipe broke off flush from my muffler. Took it to these guys and the fabricated a solid fix that Im sure will no longer cause me any issues. Fair price and easy to work with. Will definitely be back next time I need some work done!

Been in talks with Matt about some suspension work I had planned for my mustang. He got me in ASAP once Id settled on the parts I would have him do vs the parts I would do myself.Had him do my springs. Got a great price and was in-out in under 2 hours. Great guys there, him and Phillip both. They know their stuff for sure.

🗣Awesome guys! Best price I could find in town. They took care of my baby, she don’t squeak no more.. 😉😁🙌🏼

With little notice, I was able to have my muffler replaced in a very timely manner. Staff is courteous, professional, and knowledgeable. The bill was fair, and the car runs fine.

Matt is an excellent mechanic and knows his stuff. If you own a mustang or any performance car, or just a regular car, Matt can take care of it. Phil runs a great shop and has the best in the area.

Top notch service at all times. Extremely knowledgable, Excellent turn around time and quality work.. Have recommended and will continue to recommend this hidden gem

Phil was down to earth and worked with us on coming up with the most practical and efficient solution. Thats on top of completive pricing!

Phillip and his staff were great. Very professional. Excellent service. Thanks for everything.

Dropped off my truck on a Friday morning for some extensive exhaust work, and had my truck back the following Saturday night sounding better than ever.

Went to Matt at ATM for a downpipe install on my Mustang Ecoboost. Matt knew exactly what to do and got the job done quick but did not sacrifice on quality. Great customer service and pricing was very fair! Will be back for all my mustang needs.

Phil was honest and fair, and Ill definitely be back! Highly recommended!

Took my car in to get an intake and throttel body installed and could not be happier with the results or the service. Phillip, did an amazing job, on time and at a great price.

Real helpful friendly reasonable price been looking for a mechanic since I moved to waldorf now Im happy to say i will do future business there thanks for the great service!

ATM was professional and knowledgeable as well as eager to solve my dilemma in a timely matter in order to pass Maryland inspection. I would trust them again for any automotive needs and you should as well.

Called in for an oil change the day of, was in and out within 30 minutes. Good service.

Excellent service I am sorry for my previous post in the email.

Needed to upgrade my intercooler, Matt had me in & out on a second. Honest pricing and amazing work.

Exellent work, took my Z28 to the shop and dropped it off to Matt. Very proffesional and neat work. Ill be bringing more cars to him.

These folks really know what they are doing when it comes to performance equipment and tuning. I would recommend ATM Automotive to everyone.

They do great work and prices are great
