Javier has always taken great care of our cars. His diagnostic work is thorough so we dont install unnecessary parts, plus there is great follow-up after work is completed to make sure everything is as-expected. Would highly recommend.

Javier is the only person I trust to work on my car. Recently I had an intermittent oil pressure light go on. It would only turn on for a second and it was easy to miss. Low or no oil pressure can ruin an engine. Any other shop wouldve immediately replaced the oil pump. After talking to Javier and explaining what I was experiencing, he checked the oil pressure to confirm. There was plenty of oil and pressure which pointed to a sensor. He replaced the sensor and I havent had any lights go on in the dash and the engine is running great. He really troubleshoots the problem so he can find the root of the problem. All other repair shops (especially dealers) will start replacing multiple parts before they find the issue which leads to an expensive repair bill. Even though I now live 30 miles away, Ill still take may car to JM Auto Performance.

Having Javier tune my suspension for Road Racing was the best investment I made for my 2016 Mustang Gt. The Balance of the car now is immaculate compared to before. I will definitely be doing business with him and his team again. Words can’t describe how happy I am! Thanks JM Auto Performance.

I was in immediate need of radiator hose repair on my Porsche Panamera. The dealer wanted to see me a month out and I called this highly rated shop in Chamblee. Not only could they see me that day, they had the part in stock. I believe I saved A LOT of money and was back on the road in under 5 hours. I will most certainly be calling JM Auto Performance for my future needs.

After having the best experience and services at JM, this is the only place where i can have an honest crew to solve any problems that my vehicles could have. Anything that needs to be repaired accurately they will let you know ans get the job done! If you’re looking to fix your car issues this is the place.

If you are like me and have had one horrible experience with a BMW Mechanic after another Please take your car to Javier. If it wont make it there he will arrange for towing by the nicest and most professional towing company ive dealt with. Javier is knowledgeable professional and detailed in repairs needed immediate and what can wait. This is the absolute best experience I have had with a shop and I highly recommend.

These guys did a great job fixing an issue my previous mechanic messed up. I had a new exhaust system installed on my old Tahoe and the exhaust manifold bolts were broke and the muffler was installed the wrong way. Thankfully JM Performance was able to repair the manifold and it did not have to be replaced and they corrected the other issues with the muffler. Javier did a great job explaining everything they did and everyone there was extremely professional and nice to work with. I will definitely use this shop again.

This was the absolute best experience Ive ever had at any auto repair shop. Ms Kunna greets you awesome customer service and Mr O and his staff of mechanics are very knowledgeable and helpful. Now that Ive found JM, I wont go anywhere else and I highly recommend them to anyone.

I live in California and was considering purchasing a Porsche Boxster S from an auto sales lot in Marietta, GA. Thank goodness I found Javier Mendoza at JM Auto Performance to inspect the car first. EXPERTISE, AMBITION, and PASSION are what sets Javier apart from any mechanic you will ever find. Javier provided an inspection of the Boxster S for a fee that was worth every dollar. Javier drove to Marietta, ON HIS SATURDAY OFF OF WORK, took multiple pics of the car, a video while driving the car, and provided his professional expertise on the condition and history of the car which was essential information when I was considering to purchase the car. Javier advised the immediate repairs that would be required and short term repairs as well. Undoubtedly the most knowledgeable, professional, and accommodating mechanic I had the pleasure of doing business with. Unfortunately, the car was a thumb down and Javier saved me from purchasing a car that was in need of too many repairs to consider a viable consideration.

Fantastic local mechanic shop that specializes in repairing all German car brands! I recently purchased a 535d and they just competed a brake fluid flush for me but Doug and his team were extremely knowledgeable having worked for a local BMW dealership In Atlanta. I would definitely recommend them and plan to stop in for my next oil change or whatever repair is needed. Thanks again!

AMAZING mechanics!! I came in to change my cv axle but had another concern about my civic making noise as soon as you turn it on. Javier suggest to take it for a test drive so he could have a better listen. As soon as I turned it on Javier knew what it was! It was my motor mounts! My previous mechanic never could identify that noise but Javier quickly knew. Danny worked on my car, and thanks to them both I can actually enjoy my car rides and hear my music playing! I want to also add every mechanic at this job is super reliable. Doug, Danny, and Javier, I trust them all with my vehicle, and will be recommending friends and family from all over!

My 1984 911 had a mysterious pull to the right which could not be adjusted out by an alignment. I was fortunately referred to Javier who diagnosed the problem as a weight in balance. The adjustment took care of the pull and she drives like new. I have also relied on Javier to upgrade the front shocks and replace the worn front wheel bearings which furtherimproved handling. Its great to deal with someone who knows his stuffcold and is excited about his work. Javier is that guy!

Javier and the team are a pleasure to work with. I had a massive difficult issue with my ECU and Throttle Body. Javier stuck with it over many frustrating twists and turns and solved a problem that most people would have given up on.Recently, I had a straight-forward cooling issue and the JM Autoperformance team diagnosed the issue, called to confirm the repairs with me, and fixed the car one and half days after I dropped it off.I couldnt be happier with the work Ive had done at JM Autoperformance. Keep up the great work!

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 brought my Porsche 911 993 TT with a new KW coilover suspension setup to Javier, since I had heard he does the best corner balancing in town. When he told me he needed to drive the car first to feel the car, and then to discuss what I want the car to do to be able to find the right setup, I knew he was the right guy. 4 hours later I had a perfectly balanced car, improved cornering in the curves, improved handling in any situation, and much better power distribution for acceleration. He also changed the ride height 3 times (!!) until he was happy. Javier is a perfectionist, and his passion for cars is contagious. Thats why I let him now also do the necessary valve retorque after the recent engine rebuild. I can highly recommend Javier at JM Auto Performance!

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. Ive 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 👍

Javier is a great mechanic who knows his cars, is affordable and gets it fixed in a timely manner! Ive 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.

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. Ive 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!

I was recommended to JM Auto Performance by Gran Turismo East. Javier and his team were very friendly when I arrived. The location is a little difficult to find as theyre on the side of the building toward the back.Its a small locally owned shop. I wasnt sure what to expect but I trusted the recommendation by Gran Turismo East. I had all sorts of ABS/Brake warning lights on my vehicle that needed to be taken care of and I didnt want to go to the dealer as I recently found out they were trying to get me to replace rotors & pads that were unnecessary. Gran Turismo & JM both confirmed the rotors & pads were in great shape. Once I got home I read the google reviews and felt comfortable that JM would take care of my vehicle.I spoke to the owner, Javier and he explained how he was going to diagnose the issue. I had already done some preliminary searches on causes of the problem so I felt informed and it aligned with what Javier diagnosed as the issue. Its been a little over a week and everything is working great on my vehicle.The shop is about a half mile walk from the Doraville Marta station which made it really convenient for me access transportation without the need of a rental. I highly recommend Javier and JM Auto Performance. Ill be back and glad to have found both Gran Turismo & JM Auto Performance for my auto repairs. I have complete trust in both. Never going back to the dealer again.

Review №38

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.

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!

GO TO JM AUTO PERFORMANCE!!!! Dont 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 youre in some car trouble, dont go to a big chain, go to JM Auto Performance.

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 didnt 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.

Id 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

Review №55

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.
