  • A Great Master Technician, Derek conducted an analysis and evaluation of my 530i which was spot on with the recommendations from the half the cost! We would recommend him without hesitation!!!

  • Consistently dependable, knowledgeable on anything-BMW I am OCD, anal as all heck when it comes to my '01 M3. Not only does Derek ALWAYS resolve the issues quickly and thoroughly, he tolerates my need for perfection. And, he never up-sells me, even though I am an easy target. Can't say enough good things, but fundamentally, and what matters most, Derek really has extensive domain expertise on BMW. I trust his work.

  • As a woman I am very reluctant to take my car to dealerships and other garages because I do not feel like I can trust them. When I first met Derek about 2-3 years ago he made me feel comfortable immediately and I knew right then and there that I could trust him. Even though I have purchased my BMW's through a reputable dealer I still go to Derek for everything! His passion for BMW's makes him truly an outstanding mechanic and business owner. I also love the fact that he will follow up with you and stay in touch just to see how the car is running. You will never get this type of service at any other garage/dealership. He provides great service and I believe you will become as faithful to Precision BMW repair as I have!

  • Derek is amazing, thorough, and dependable. He has helped me out in a few binds where I couldn't even get my car to his shop. I trust him more than a dealership, and can count on him to give me an honest quote, he also examines the whole car and let's you know what you might need down the line. It's refreshing to find someone you can trust that has such a passion for BMW's -this is my second and I only take my cars to him.

    All I can say is AWESOME! Mila was very quick to respond to my inquiry. They ARE busy for a reason, but they made every effort to accommodate my schedule to get me in. What I thought was a transmission issue, Derek immediately knew without looking at it was a spark plug issue. They had all parts in stock and were able to fix it same day (I was far from expecting this). To further assist, they gave me a loaner for the time they were working on my vehicle. From first call to payment, they were a pleasure to work with, honest, and thorough in explaining what was happening, why it was happening and other things to be cautious of in the future. Couldn't recommend them! Already passed his info on to my neighbor who will be calling them for future work on his vehicle!

    This is the best place to take your BMW. Derek knows BMWs like no other. They provide great service, underpromise and overdeliver. We had a complicated “check engine” issue among other things, and they were up to the challenge as usual, resolving our issue in a timely fashion and getting our BMW running great again. I wouldn’t take my BMW anywhere else.

    Derek and Mila are phenomenal at Precision BMW. They are true professionals that strive to provide the best service out there. Not only offering excellent service for your vehicle in a timely and cost efficient manor but will gladly lend outstanding car buying and service advice. They will always put you first making you feel like you've known them for years, something most mechanics lack these days. They are true professionals that strive to provide the best service out there 10/10 in my book.

    We brought my daughter’s 2013 BMW X1 to Precision after our mechanic recommended we find a specialist with the proper equipment to diagnose. From the initial phone to the final review of the detailed repair estimate was a very satisfying experience. Mila was great to deal with and she shared video evidence throughout the entire diagnosis. Though the repairs ended up being cost-prohibiting, we greatly appreciated the work Mila and Derek put in to diagnose and provide a very detailed estimate of repairs. They are highly knowledgeable and capable of diagnosing and repairing any BMW. I would highly recommend them for any repair service you may need.

    I was referred to Derek Najarian's service facility based on a customer's recommendation and being extremely knowledgeable on the BMW vehicles. i was very impressed with his friendliness and "can do" attitude and his technical expertise on the BMW. He got the job done at under the estimate and took care of all the things needed to tweak up the vehicle and did it in a short period of time, which very much impressed me and now i understand why he has customers throughout New England who bring their BMW's for him to maintain, take care of, keep it tweaked, and deliver way beyond expectations and not have to take it back a second time. That is hard to beat today. I highly recommend Derek for his BMW service ability. Brad Willette

    I have been taking both of my BMWs to Precision BMW for over 6 years and I will continue to do so as long as I own a BMW. Derek is quick to diagnose any problem and will give you sound advice as to what needs to be repaired immediately versus what can wait and what to watch out for in the future. Precision BMW is a true dealer alternative that provides friendly and convenient service at unbeatable prices!

    I sincerely hope that all BMW owners can have the very good service I received from Derek at Precision BMW. I was pleasantly surprised when I drove my car after getting it back from Derek, simply put - it was fun again - I thought it had gotten too old. Derek diagnosed my car the same day I dropped it off, provided a loaner, and readily returned my vehicle in working condition. The experience was pleasant, fun and informative. I felt as if Derek lived and breathed BMW's from a purist point of view. This guy even anticipated a part I briefly mentioned re: GPS in an earlier conversation - he listens to his customers! I definitely recommend Precision BMW.

    Have you met Derek yet? You should if you own a BMW! I just met him today, he came to my home, diagonsed the problem and fixed my car! OMG I would have had to have it towed. He knew the problem based on my short email. I always had my car serviced at the dealer....not now, he saved me approx. $300 on my repair. He is extremely knowledgeable about BMW's, although I tried many times to get the dealer to discuss the upcoming necessary service items...all I got was "this car is in great condition". Yeah I really want to know what it needs for preventative work, I can tell you Derek will only lead you to preventative maintenance before it becomes a problem. I am forever a fan. Thanks so much! I Love my BMW! CC 2008 BMW 328XI

    My BMW z4 recently had a problem in which I received a quote from a local BMW dealership. I thought the quote to be excessive. I then found Derek at Precision BMW Repair while searching for BMW alternative repair sites. The problem was quickly resolved at a prove far less than was quoted by the dealership. I found that Derek has a passion for BMWs and he is a person who I will trust my car to. I also did not expect to be provided with a loaner car. This was just another part of his great service. We'll be back for sure.

    Having been to many dealerships and repair facilities it is so refreshing to find Derek and Precision BMW Repair. Derek is a true gentleman and his honesty shows through along with his immense knowledge of all things BMW. My car was repaired in perfect fashion with no surprises or upselling. Finally, I have found a repair shop that I trust to do what I need done.

    After realizing how expensive it was for out of warranty repair, I needed to find an alternative. I found Derek at Precision BMW Repair, and am glad I did! Derek did a very thorough job and cost much less than the dealer. He even found a pretty big issue that the dealer missed. The car was ready when he said it would be and the estimate didn't change. Also having a loaner is always a plus! My car won't go to another mechanic again!
