  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.

  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!
