This is by far the best mechanic I have been to in NEW ENGLAND, I’ve gone to over 5 different mechanics and still haven’t received the quality, clarity, professionalism, and care that I received with Josh and his employees over at peak performance bmw, these guys know exactly what they are doing when it comes to fixing German automotive, weather it be simple maintenance, swapping out broken parts, to even adding some of the most brutal performance enhancing parts on the market. Whatever you need done I can 100% guarantee that you will get the satisfaction you are looking for when you hand these guys you’re keys. I have been trusting josh with my car for over 4 months now and I could never see myself going anywhere else but here. I can promise you these guys are the real deal, Everyone I’ve sent his way has said nothing but positive things and continue to be an ongoing client of his. This guy build cars on a weekly basis that are pushing well over 500-600hp, as DAILY DRIVERS so if that doesn’t already say enough I don’t know what does, by far the best mechanic around!

Josh, Sam and Cole are by far the coolest people I have ever met. They’re always willing to go above, and beyond! I love when they always add a little spice up on my car! The build I have currently is on a big single turbo conversion precision 6266 by Speedtech kit and builder was done by Josh.I live 1hr and half away from their shop and you know what I don’t care because they’re by far the best shop out there for our cars!!These are the guys to go for your aftermarket performance, and maintenance!!

Peak performance is the best BMW shop out there or any European car in fact, they just did my single turbo conversion on my car to make it 800hp ready and the work is more than beautiful even did more work and never charged me for it, work came out clean and the car never had issues after I got it to them, very honest people and prices are great for what you are getting!!

Great car upgrades and auto mechanic! Josh and his team go to the outer limits to make their customers happy and perform high quality service. After discovering a manufacturer’s defect with our upgraded CarPlay unit, Josh and his team worked diligently to guide us through the replacement process and took care of everything soup to nuts. He’s one of the last mechanics we have worked with that actually cares about his customers and making sure the job is done right. We will definitely be back and recommend him highly!

These guys really know there stuff. I high recommend them for anyone who has a BMW with an N54 or any other euro car. They are knowledgeable and have amazing customer service and will treat your vehicle as if it was one of their own cars. I recommend this place 10/10. I won’t be taking my car anywhere else but Peak Performance.

Peak Performance is your premiere performance and modification as-well as repair and diagnostic facility in the Boston/NH area. Josh is as knowledgeable as it gets when it comes to any BMW and is a pleasure to work with. I took my car there originally for a small oil filter housing repair which went flawlessly, then ended up ordering all the components for a big single turbo kit through them. The work they performed on my vehicle was second to none and I couldn’t recommend them enough.

Awesome shop! Josh the owner seems like a great dude. Very friendly and knowledgeable. I would definitely highly recommend!!

One of the best places you will ever visit in your lifetime. Josh and crew will tell you exactly whats wrong and not beat around the bush. They offer amazing service, advice, and cost.

I store my E36 M3 at Motorloft (also an excellent business!) in Derry, NH and I mentioned to Tony that my car needed service, Tony referred me to Josh at PP&D and Josh and his team did a fantastic job of diagnosing an engine misfire that two other well known shops could not!Suffice it to say that I would highly recommend this shop to anyone who owns and loves BMWs other foreign exotics!

The team at Peak Performance know their stuff. Joshua Perrault is an awesome car mechanic. His attention to detail about BMWs is impressive. He went out of his way to explain everything that was done on my E90 335. I would recommend to every BMW owner to checkout Peak Performance if they ever have any issues with their BMW.

The guys over there at Peak Performance are the real deal. I was having all sorts of issues with my e92 335i and a friend mentioned there name to me. I have since gone on a crazy journey with this shop fixing my now incredible e92. The only drawback to the shop is that it has very limited staff. With that being said I was still able to get a hpfp installed as well as my injectors and numerous small here and there’s. I’m very pleased to say my car is now running as it should and I couldn’t thank Josh, Sam, and Cole enough. I would highly recommend this shop to anyone in the area that owns a BMW and doesn’t have time to deal with shops that tell you the problem can’t be fixed or even worst the “stealership”. They even took the time to make sure I was happy with what they had done and even while I waited I was able to bounce ideas and questions off of their knowledgeable minds. This is the shop I will always bring my baby too. Without question!!!! Keep up the good work guys you are very much appreciated!!

One of the best shops to get your cars needs done. totally would recommend going you will be happy to get services done with them easy to work with trained professionals

Josh did a wonderful job installing a VRSF exhaust on my 335Xi and that exhaust wasn’t even supposed to fit my car but his a wizard with fabricating stuff to make it fit your car!!

Have heard nothing but great things from 5+ buddies that get serious work done here. If theres anything I cant resolve on my own, I know where to take 335 without worry.

Look no further, josh at peak performance is simply the best cleanest work around and very knowledgeable!

By far one of the best Mechanic shops I have ever been to in a long run. Josh makes sure everything is done 100% right the first time and never has to look back at it. He goes out of his way to do all the little things and it’s just crazy to see how much dedication he has just from talking to him. 100% recommend Peak Performance to everyone and anyone for your Euro needs! You won’t regret it I promise that!

Fast friendly and knowledgeable. What more can you ask for. My regular BMW service tech closed his doors and just my luck the following week Joshua happened to stop my work when he noticed my 535i and introduced himself. I didn’t need anything at the time but kept his business card in my wallet. Fast forward to two days ago sitting in traffic and the temperature outside read 98 degrees and my climate control was on 67 but it was blowing warm air not cool. Josh had it fixed in two hours and changed my oil too and informed me of some future work I might need. Great guy

Excellent service, very professional, clean shop. Josh is amazing he will probably diagnose your BMW and guarantee his work. Literally dealership grade and almost half the cost! Saved my E92 N54

Josh will go above & beyond to make sure you’re more than satisfied with your car after he’s done.

Great costumer service, Josh is awesome to deal with. Would highly recommend!!!
