    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.

    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! Joey very unprofessional with the profanity

    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.

    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 very knowledgeable, and their work was top notch. I'm looking forward to having them do some performance work on my M4 F83. 5 Stars is not enough; they need more stars than 5.
