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

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

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

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

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!

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!

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.

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

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

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!

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!

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!
