  I had a top-notch experience with Peak Performance in Derry with my VW. Everyone there was extremely knowledgeable, professional, flexible, and honest. You can tell they genuinely have a passion for what they do and take pride in their work. They took the time to clearly explain everything and were very confident in their recommendations, especially when it came to safety and preventative maintenance. I never felt pressured, but I also appreciated that they were direct about what they felt should be addressed and why. Their pricing was very reasonable, and I truly appreciated how straightforward and trustworthy they were. It’s not easy to find a mechanic you can feel confident in, and I would absolutely recommend Peak Performance to anyone looking for reliable and honest service!

  They treated me like I've been there before on my first time there. Great group of dudes loving what they do, they tell you whats what and will work with you on what needs fixing and what can be skirted. Will go back back at some point

  I gave Peak Performance several opportunities to earn business, but the experience was disappointing from start to finish. An appointment was scheduled for my vehicle, yet when I arrived there was no clear plan to properly diagnose or repair the issue. Over the following weeks, we reached out multiple times, shared information that might help identify the necessary parts, and tried to work collaboratively toward a solution. Instead of receiving clear communication or a defined repair strategy, we were met with inconsistent responses and ultimately made to feel responsible for the shop’s lack of progress. After weeks without a diagnosis, repair plan, or meaningful updates, Peak decided they would no longer work on my vehicle. Professionalism means communicating honestly, setting realistic expectations, and taking ownership when problems arise. Unfortunately, we experienced the opposite and an utmost lack of respect. Based on how this situation was handled, we won’t be trusting Peak Performance with any of my BMWs in the future and nobody should trust them with their vehicles.

  Extremely unprofessional and genuinely incompetent. After an appointment Peak scheduled, they were not prepared to properly assess my vehicle and never identified a clear repair plan. I made multiple attempts for weeks to communicate and even provided information on possible parts, but instead of working toward a solution, I was blamed as the customer and no accountability was taken. After weeks of poor communication, despite accounting for personal limitations, Peak ultimately refused to move forward with repairing my vehicle. There was no clear diagnosis, no plan, and no effort to resolve the situation. Honesty, transparency, and respect are everything in customer service. Blaming customers for scheduling issues, lack of preparation, or an inability to properly manage the business is unacceptable; after this experience, I will not be returning any of my BMWs here.
