Peak Performance & Diagnostics

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.

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.

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 took my BMW to Peaks Auto Performance for a diagnostic, and they told me I needed a whole new engine — a repair they quoted at around $12,000. That immediately sounded suspicious, so I decided to get a second opinion. The other shop found that all I needed was a timing chain replacement and an oil change for under $700. My car is now running perfectly. Peaks either completely misdiagnosed the issue or intentionally tried to upsell me something I didn’t need. Either way, it’s unacceptable. Be very careful before trusting their “diagnostics” — I won’t be going back. I wish I could give negative stars AVOID BUNCH OF KIDS WITH YOUR CARS DONT WASTE YOUR TIME OR MONEY!
