Honest and very high quality automotive service and repair.

Highest quality parts, excellent diagnosis skills, no upsale and job gets done the way it needs to get done, the right way!

Javier is an honest straight forward mechanic. I don' t take my vehicles into shops very often, as I prefer to take care of my own repairs (on account of my experience with a lot of mechanics doing shotty work, or overcharging, or trying to up sell repair work, I have some horror stories...) I called to drop off my Audi at JM Auto to have my A/C system evacuated and recharged after I had replaced some HVAC components. Javier made time for me that day, and even stayed late to make sure I had my car back later that evening. His price was very fair, and he went above and beyond by printing out a complete diagnostic report for my vehicle (the dealership would probably charge $125 for that report). He took time to chat with me about car repairs, and knew quite a bit about my specific vehicle. After talking with him and looking around his shop it was obvious he knows a lot about nearly all makes and model of vehicles. I will definitely do business with JM Auto Performance in the future. My A/C is ice cold.

Great repair shop! Like ourselves they are a family owned business that prides themselves on providing excellent service! This may not be the cheapest shop around but the head gasket repair was accurate, on time and our vehicle is back in business. Thanks again.

Best shop un town

I brought my car to Javier after calling several shops about my rack and pinion which has been off centered for several months and not driving right. Out of all the shops I called, I decided to follow my instinct and go with Javier. Javier was not only professional, but took the time to explain what would be done to correct the problem . He also inspected the car for any other potential concerns and explained them to me which made me feel at ease. It is very rare to have a mechanic be willing to take the time to talk to you about your car and answer any questions that you may have. I will definitely refer anyone to him.

I was referred by Gran Turismo East to stop by here for a battery calibration on my Porsche 991.1. The owner was amazingly friendly, and didn't mind me stopping by with short notice. I was in and out in record time! Based on his enthusiasm, and the service I received, I would most certainly return for maintenance in the future.

Great Service! Very trustworthy and dependable.

Javier is a great mechanic!! Honest, knowledgeable, and loyal. I will definitely recommend his services to all of my family and friends that are in need of mechanical service.

Javier is a great mechanic who knows his cars, is affordable and gets it fixed in a timely manner! I've taken my car to 2 other mechanics who just ran a whole bunch of diagnostics and my car continued with the same issue for a year! I told Javier the issue and quickly knew what it was, he made sure to confirm and within hours had it fixed! My car has not run this smoothly since I purchased it, definitely will be sticking with him for any future issues.

Javier is a true professional ( engineer) and he knows cars! He can fix anything from a Ford to Ferrari, while charging a fair price.

Excellent attention, quality of work and delivery on time! 🥇

Javier is the absolute best! Would not trust anyone else with my vehicle.

Javier is the best of the best.

They were able to put my lift kit on I got online. Great shop!

Javier guy was awesome to work with, very honest and to the point person and uses OE quality parts for our car. He worked on rtabs on my '97 M3 and did a great job with it. I would highly recommend JM Autosports for you car repair/maintenance.

GO TO JM AUTO PERFORMANCE!!!! Don't try to fix your car yourself. The hub assembly on my truck was rusted together with the knuckle. Initially I tried to replace it myself, but after beating it with a sledge hammer, I took it to Javier. He asked me when I dropped it off when I needed it done...I replied, "Last week!". Unfortunately, he said there was an additional charge to go back in time, HOWEVER, literally in a few hours the truck was done. Great guy, great shop, great prices. If you're in some car trouble, don't go to a big chain, go to JM Auto Performance.

EXCEPTIONAL customer service. I was greeted by Javier with a smile and warm spirit and immediately felt like I was in good hands. He quickly found the issue and got to work, he even showed me the faulty pieces and new ones he replaced them with. It’s not often you find such trustworthy mechanics. I will definitely be back but hopefully not too soon.

I moved to Atlanta just a year ago and, whenever I move, am nervous about finding a good mechanic for my little car. Javier is great and incredibly accommodating. I've taken my car in twice now- one emergent issue with my window that he fixed that same day (a necessity in december right before heading out for the holidays), and another day he came in early so I could be to work on time. Great service, reasonable prices, and highly knowledgeable!

From the first time i spoke to Javier about taking a used car i was thinking about buying to get inspected, you could tell he is honest and truly cares about customers. I was able to make a same day appointment and take the car in. It was not found in the greatest condition and Javier took his time explaining why the car probably would not work for me. I definitely trust his opinion and never felt rushed out of the door once we found the car was not a good buy. I've already referred him to a couple of people I know because i feel as though he is a mechanic that can be trusted and knows his stuff 100%. He will definitely be my new mechanic from now on 👍

The Best Service, and fast!!!

As a single female I was not intimidated into any services. I felt as though I was respected and all of my options were provided to me in an HONEST and COURTEOUS delivery. I would recommend Javier and his shop. He was able to walk me through the "BIG PICTURE" for the state of my car. If you are looking for a auto repair shop, you have just found it!

A big shout out to Javier at JM Auto Service for figuring out why my AC compressor quit blowing cold air. He is to cars what Cesar Millan is to dogs. My AC quit blowing cold air was told that I needed a new compressor by another tech. After driving around with no AC I decided to get it replaced. I talk to Javier and he encouraged me to come in the same afternoon I called to check it out himself. I really appreciated his genuine concern about my driving without a working AC. He meticulously took the time to check every possibility for the problem and then resolved the issue. What was going to be a $800 job cost me the time of day to visit Javier. My compressor is working perfectly and I am now chillin like a villian.

Great honest work at an affordable price. You name it and Javiar can work on it! I was first referred to him by the guys at Gran Turismo East and have had no regrets about going there since! A good and honest mechanic is hard to find but with Javiar you are in great hands!

He is a very thorough and trained mechanic he patiently dealt with my warranty and they sent a not so good transmission and he declined it and made them send a better one he cares about his customers

Javier and the guys at JM are the best. Took my Mercury to 4 places trying to solve a front suspension issue and these guys nailed it. Best the car has ever driven and the work was done quickly for a fair price.

I honestly cannot praise JM enough for his honesty, pricing, integrity, and overall great personality. There is a reason why his place is 5 stars.. The only reason why I am writing such a long review is because he deserves to get the same respect in return with a great review!

I'd been to several mechanics to repair my emissions issue and none of them fixed the problem or even knew what the problem was. Javier at JM Auto Performance was the only one to find the issue and fix it. In addition, he is also very thorough, knowledgeable, and honest. From now on, I will only trust my car with Javier at JM Auto Performance. Pam

JM serviced my car last week from a breakdown. Javier went above and beyond the call of duty to help us in unfortunate situation. My fear level of car trouble...OVER. The service was excellent, Javier was on point in what was wrong and the price was worth it's weight in gold. I can't be happier with this company. I have finally found a Star mechanic. You can keep looking but sometimes it's time to trust the a true professional. Highly recommend!! Glenda

I'm happy with the outcome and customer service highly recommended. A bit steep for the cost ,but understanding for a job that wasn't easy. Thanks,

Javier is a professional who understands and appreciates his customer's various situations and cost options when repairs are necessary. He is accessible for phone calls, open to questions, and offers complete service from written estimate thru repair and billing.
