In rare circumstances do I wish I could give more stars... A prime example of excellence, professionalism, dedication to craft, and just great people is the guys at Extreme Motor Sports LLC! Every car I have ever owned was serviced explicitly was EMS Waltham. They have always been upfront with the work, time, cost, and ability! Never have I seen such transparency in a shop before! If something is going to cost more, or take more time I am notified immediately! All my friends have been sent to them as well with no remorse! They take care of everyone as if theyre family! All business have their share of good and bad reviews/ experiences but not at EMS! They hold true to their values and never ever disappoint! I will always be a life long customer! If you need anything done to your vehicle whether its maintenance, or modification they are the guys! True motorsport enthusiasts!

I was recommended to EMS by one of my friends and I was certainly more than pleased with my service. Stan and Alex are a very great team, providing a level of honesty mixed with quality that is hard to find from many other auto shops. Would definitely recommend anyone in need of any kind of car repair or maintenance, I dont know if it can get any better than the team at EMS.

I brought my Chevy Cruze in to check out a check engine light. They were extremely professional and walked me through all the issues and gave me a very fair price. They even helped with the cost of a rental when they determined they would need to keep the car longer then expected. Absolute 5 star experience. Alex is awesome.

I brought in my Honda S2000 for a much-needed alignment to this shop and these guys are absolutely awesome. They inspected and test drove the car beforehand to make sure it needed an alignment before doing it, and they test drove it after to make sure the new alignment was good. My car was lowered and pretty much no other shop would do an alignment on it, but these guys worked patiently and very hard to get my lowered car onto their alignment machine. As I drove away the car handling felt awesome, and the alignment they did even removed a sticky spot in the center of the steering so the wheel turned much easier now. All three mechanics I met here here were extremely friendly too, Ive never seen this before at any other shop. Finally I think the price they charged was very reasonable. I would definitely recommend this shop to anyone who wants quality service on their automobiles, especially those with performance cars, as the guys here really know what theyre doing and seemed very trustworthy. They have recently moved into the space that used to be Donovans alignment after Donovan retired.

I personally recommend this place to everyone ! I met these guys a few years back and they have been a godsend, saving me $$$$ & helping me keep all my cars running & in amazing shape. They do amazing service, repairs, upgrades, they do pre purchase inspections, sell tires along with Mounting & balancing, alignments, they service motorcycles. It’s a one stop shop for all your car needs!They took care of so far 4 of my cars along with my wife’s car. They are honest, hard working & do quality repairs. They go above & beyond to make sure your happy. I’ve referred my whole family to them, in laws, parents, sister & countless friends.

Since I bought my motorcycle couple years ago, I went to extreme motor sports for my scheduled service. I called them first to make an appointment, andwhen the gave the date to bring it, they do a good job in a short time. If Alex is busy, he will not ask you to bring your motorcycle and just sits there in the garage for couple months.The last I did last week or so is to replace my old tires after 13000 miles. Alex suggested to me the Michelin road 5. He explained that they are good for rain and they are good for cruiser. Alex did a good job, the tires are well balanced and the ride is smooth.In 2 words Alex is very knowledgeable

Alex and Stan are a great team. When looking for any kind of service, I look for three key characteristics: Knowledge of their field, Honesty, and Friendliness. Alex and Stan have exceeded my expectations in all three areas.I discovered Extreme Motor Sports couple of years ago when looking for auto shop to replace breaks of my wifes Honda fit.Going by their, at first I thought they only fix high end cars but I called them anyways. I was impressed by the friendly conversation over the phone.After asking few questions about driving habits, Alex suggested couple of choices for brake pads and rotors and to my pleasant surprise the labor cost was very reasonable and obviously way less than a dealer.Since then, I have been using Alex and Stan for all my auto needs. Recently my 5 series had a suspension issue while driving on the highway. Stan was able to diagnose the issue and made the fix and so far no issues.Stan also replaced my 5 series brake pads/rotors with OEM parts, again at a very fair price.When I was at the shop last time, I noticed that they were rebuilding an engine for one of their auto enthusiast customer. This confirmed that Alex and Stan know what they are doing.The only thing you have to take into consideration that this is a two man shop so on days they are very busy, you may have to drop of the car or leave it overnight for them to work on it.Overall, I am glad that I have found the dynamic and honest duo of Alex and Stan for my auto needs.

Our family has found our new mechanic. I brought in a car for a pre-purchase inspection, and Alex gave me confidence from the very start. He looked over the car thoroughly, and took the time to show me various areas of concern while it was on a lift - pointing out both good and bad.He identified several issues through the inspection that I subsequently had the dealer fix before I bought the vehicle - saving me hundreds if not a thousand dollars.Since moving to New England, I have had trouble finding an honest mechanic who will take the time to talk to you. EMS is it for us. Thanks guys!

Great service at very fair prices. Alex the owner is very knowledgable and will give you lots of great tips on your car maintenance. When you need a new part, his prices are very competitive and he will guarantee the quality.

Really great team! I have been using Extreme Motor Sport for over 10 years, serviced 3 cars and followed them in all their locations. The guys are very honest and provide high quality work. Its a rare thing when you can find a mechanic you can fully trust. They take time to explain the issue and I always feel like I am making an informed decision when I need something fixed. I think 5 stars is not enough to express the gratitude I have for Alex and Stan from Extreme Motor Sports!

If you love your car then this is where you will need to bring it. Alex & Stan are incredibly passionate about doing quality repair work but also customer service and making sure you and the car is taken care of. They know a lot of the intricate details that only dealers might know about the cars and can truly diagnose them. From high end sport cars, to suburus to my lifted toyota 4runner they do an amazing job and use high quality parts and are an incredible value.

Fast and reliable! Did the breaks and rotors on my rdx in no time! Thank you!

Great people who seem dedicated to letting you know what exactly is going on and trying to give you the deal you want. Love it!

Extremely friendly and knowledgeable team. Stan and Alex do their absolute best to make sure that all customers needs are taken care of. They specialize in both domestic and foreign cars and motorcycles, with a focus on custom builds as well as regular maintenance.

I feel like, professionally they maintain business ethics of high standard.I found Stan and his colleague Alex reliable and trustworthy.

I know Alex and Stan for three to four years now. I was introduced to their repair shop, when I was towing a motorcycle for a client, to be dropped off there, and I was extremely surprised to see how professional and curious these gentleman acted, and how clean and organized the work area looked. Later, I learned from my other client David, that he used them to fix this Mercedes, and the guys do a great job and are always fare, so Ive also started to bring my cars for service here, including my nightmare ford taurus, which I apologize was a trouble car, but even with that they handled it very professionally!

Thank you!Great tires,great service !

Alex and Stan extremly professional. Explaining to me all things they going to do and no unnecesary extra services been added.Every thing was discussed before doing and no mental pressure about some future work. Simply the BEST.

Courteous service, very knowledgeable about cars, great experience!
