A True BMW Specialist & Dealership-Alternative In Derry, NH

After dealing with cylinder misfires on my A3 for four years, Peak Performance diagnosed and took care of the problem. I’ve been to 3 other shops but none were able to resolve the issue. I was impressed with amount of detail they shared with me throughout the process. Highly recommend.

After being disappointed recently with another euro shop that I had along time relationship with I thought it was time to give another shop a try. I chose Peak Performance to complete a seasonal tune up on my Porsche Boxster, I found the shop just from an online search and decided to roll the dice based on their reviews. Making an appointment and dropping off the car was relatively easy. Communication was out standing, Peak performance completed a full inspection of the vehicle documenting every

George Contis

Such a good experience with the guys here. I was pressed for time on a repair on my wife’s x3 and they managed to squeeze me into their busy schedule same day. Having worked in the auto industry for years I am very picky about what shops I trust, especially with a modified vehicle. The crew here are true enthusiasts, and will now be my trusted shop for any maintenance or mods that are over my expertise level. I’d give a sixth star if I could.

Daniel Bullock

Excellent customer service from these guys! I came in with some questions about work on my car and they walked me through the process and gave me a fair quote. On the day of service, they kept me in the loop and were very helpful getting me back into the vehicle after the work was done. I haven’t had a chance to drive it yet, but I’m sure they will be right there with me if anything needs to be addressed.

Recently moved to NH, and have a 2020 BMW 330xi. This place came up and Peak Performance has been my go to spot for routine services since. Highly recommend, efficient and communicative.

I bring my VW Tiguan for the multiple checkpoints and oil change. The service at this shop is very professional, and timeless. My car runs again like new after Josh and his team worked on it. I recommend 100% their professional services.

I. Perdomo

Have been here a few times now, and each time I was impressed by the attention to detail, communication, and how knowledgeable the service advisor was. They don’t try to pressure or upsell you, the suggested repairs are an easy accept/decline button with all the details and costs clearly explained in the link they send you. They are clear and honest about what repairs are/aren’t urgent/important. I trust these guys more than the BMW dealership to diagnose and repair my cars correctly.

Daniil Toropov

Josh and his team at Peak Performance were excellent from the beginning. They walked me through a few different options with the repairs I needed on my Volkswagen. Great communication throughout the process. Would 100% recommend.

John Mawson

I went to Peak Performance & Diagnostics to have an aftermarket exhaust installed in my X6 and when I went to pick it up, I was amazed and in awe at the work they have done, especially installing the carbon fiber exhaust tips that was very difficult to install and align according to others who have installed these exhaust tips on their vehicle. Josh and his team (Joey, Jose, & Nick) did a fantastic job. It was a pleasure talking with them and we could have talked ALL day. These guys are

Nick Nguyen

Peak has worked on my 17yo son’s car a few times now. He purchased it about a year ago and we knew then it needed some work (it’s a 2002 lol). The guys at Peak are great. They went thru his car and made up a punch list of things that needed to be done. Some more urgent than others, some could wait. We’ve been chipping away at the list and have gotten quality work done each and every time. They are fair, honest, reliable and fun to chat with!

I couldn’t be more impressed with Peak Performance! They did a fantastic job on my car — fast, efficient, and at a price that was more than fair. Highly recommend to anyone looking for honest, top-notch service!

Tina

After a many month fight trying to solve an incredibly difficult to find problem with my car and several other shops, even BMW service itself, not being able to even diagnose the issue I decided to bring it to an independent shop that specializes in BMW and I’m very glad I chose Peak Performance & Diagnostics. After a thorough search they were able to find my issue within a single day, provide a quote and even show me in person the things that were causing the problem. After the diagnosis t

Steven Wright

I went to Peak Performance to get a second opinion on my BMW X1. I had been informed by a different repair shop that my engine block was cracked and that a new engine needed to be installed, GASP! Josh, Joey, and the guys at peak were nothing short of amazing and they discovered that the engine block was indeed NOT cracked and they saved me over $9000 in repair bills. Yes, you heard me right… $9000!!! I would recommend that everyone owning a BMW bring it to this shop! I know I will be a retu

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

I only trust the team at Peak Performance to work on my G80. I really appreciate their attention to detail and perfectionist approach. They take pride in their work and I appreciate that. Just had them install KW springs and downpipes. A+++ job!

The staff at Peak Performance and Diagnostic are top shelf. They kept me informed on the refurbishment of my 94 /740i and helped me with choosing priorities to get her road worthy once again. I couldn’t have landed in a better spot to have the extensive work that was necessary to bring my 30 year old beauty back to life . I wouldn’t hesitate to recommend their work to anyone looking for expert mechanics and top notch service. Russ Sherman, Raymond, NH

Russell Sherman

This is THE BMW performance shop for New Hampshire and Maine. The level of professionalism and expertise shown by Peak Performance is unmatched in the area. I brought my 4 series to them for some upgrades, and a tune. Not only did they competitively price the labor and source the parts I chose, but also made suggestions on alternative manufactures to consider for the build. The work was done on time, within budget, and while they had the car they identified some issues that a previous shop ov

I recently took my 5-series to Peak Performance for a suspension diagnosis, and I couldn’t be more impressed. After a detailed inspection (complete with a thorough report of issues, photos, solutions, and priorities) we decided on a combination of aftermarket and OEM parts. The full suspension overhaul took less than two days. Not only does my car look great, it handles even better. Their transparency, honesty, and professionalism were refreshing compared to the dealership. Josh and his team ar

When you pull into this place and see all the employees cars, you’re instantly put at ease. These guys very obviously have a love of cars and what they do. They went above and beyond to make sure I knew what was happening with my 2023 X3M Competition and that I was completely happy with the work they did. 12/10 would recommended.

Greg Picard

I just had my BMW X3 inspected and repaired by Peak Performance. This shop is the best I’ve found. From estimate to loaner car to repair and finally pickup, these guys are great! I will definitely be a regular customer. Thanks, Peak Performance.

Pamela Whitney

These guys get an absolute 10/10 from me. I drive a decently modified BMW that I specifically bring to Peak Performance for all things maintenance and diag. I always tell them I wish I found out about them sooner because all of their work has been done right, completely, and in a timely manner or earlier than promised. Even when my car had a lingering problem, they were very communicative, honest, and stopped at nothing until they got down to the root of the issue. Not to mention they’re an enti

Joel Karara

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

PattyPsi

absolutely 10/10 blew my expectations out of the water. i brought a recently purchased vw in for a faulty sensor, and they were so quick and honest about the diagnosis and cost. they worked with my warranty as well. i was highly recommended by a close friend and i honestly can’t recommend peak enough. they sat and had a conversation about just cars in general, and i didn’t feel uncomfortable or like i was bothering them at all. genuinely best repair shop i’ve ever interacted with, i 100% r

ava millward

Peak and the entire team went above and beyond on my repairs to get my car back on the road. I can’t thank them enough for picking up a job that another mechanic botched, and making it right for me. I can’t recommend them and their team enough. They were professional, courteous, communicative, and quick. Thank you!

Steven Brown

I’ve Brought my Porsche Macan S into the shop on two different occasions for simple oil changes. These guys beat Porsche prices for the service and found other issues with my vehicle. They really know their stuff and I’ve left with peace of mind each time. Highly recommend!

James Albert

This shop is prompt with responses, completely transparent, very informative, and all around wonderful to work with. They did both performance, and maintenance work on my audi and I couldn’t recommend them more! The whole process was clearly laid out, they had an excellent turn around time on the work, and kept me informed along the way, ill be taking my audi here for the foreseeable future.

Matthew Wallace

I had purchased an Audi TTS convertible from an out of state dealer that greatly misrepresented the car. unfortunately, they didn’t stand behind their car. I almost traded the car due to some mechanical issues that couldn’t be diagnosed by other local mechanics. I found Peak Performance & Diagnostics online and called them to discuss the problems. They did a comprehensive review of the car and provided all the recommendations in writing with pictures of the suggested work based on their

Jeff Gilbert

Josh & the whole crew consistently leave me feeling like my car is always in the best sets of hands when I bring it in for repairs and routine maintenance. My car is (over) 10 years old and they keep it driving like I just bought it from the dealership. I would trust them over a BMW service center any day of the week. I hope to always have a bmw just so I can keep bringing my vehicle to peak performance and have the constant satisfaction of their outstanding work. Thanks guys for all that you do

Kyle E

I recently purchased a 2020 M550i and wanted to get some work done to it. Looked at a couple of places but ultimately decided to go with Peak Performance and I’m glad I did! I had them install a mid-pipe by Dinan. Josh was awesome, super knowledgeable and great to talk to. Their customer service was great, the crew was very cool and their shop super clean. The price was fair and the results are awesome! What else can you want? Thanks guys, I will be back for some more work!

Bonafide Plumbers

Peak Performance & Diagnostics provided Exceptional service on our 2013 BMW 135i. Josh is a pleasure to talk with, very professional, and extremely knowledgeable concerning all aspects of BMW troubleshooting. My level of confidence was immediate. We appreciated the honesty on what needed repair, and what might need attention at a later date. All our future BMW service will be done here at Peak Performance. Thank you!

steve cillizza

Can’t say enough great things about this business. Josh & his team are super professional, knowledgeable, thorough and friendly. They even send you a detailed list with pictures before you approve the work. My Audi Q5 needed a lot of help and I wouldn’t bring it anywhere else. Highly recommend to any Audi owners!

Tiffany Rose

Josh and his crew at Peak Performance have done a fair bit of work on my car and everytime it is of the highest quality. They care about their customers. I trust their diagnostics and repairs. Great shop and I don’t hesistant to recommend them to anyone.
