  Recently I have done a transmission swap from SMG to manual on my E46 M3 at Zealous performance, the results were amazing!! Thanks to Daniel !! I brought the car there one day in mid March, and I picked up May 1st. But here is the great part, other than transmission swap he took care of a whole bunch of other mechanical issues , small little issues, but a lot of them, which I believe a dealer would never mention that all this things should be done in preventing way bigger issues! First time I can say that I can trust a mechanic! Daniel has great knowledge on European automotive and I encourage everyone with European cars to trust Daniel !! You won’t pay the dealer price for sure, but what you will pay will be worth each penny!!! Keep doing the great job Daniel!!!!

  Daniel and Zealous Performance is my go to when I’m looking to do something with my car. From lowering springs (VW GLI pictured) to a JB4 tune and regular maintenance (Audi A5 pictured), I can’t recommend him enough!

  My R35 GT-R was throwing lean codes and misfiring. A previous shop had diagnosed the issue as spark plugs and O2 sensors, but after completing that repair, the problem persisted — in fact, it showed up again on the drive home. My experience with Daniel was completely different. He worked closely with my tuner to properly diagnose the issue, which turned out to be leaky injectors along with multiple exhaust cracks and leaks. He provided clear documentation, including photos of cracks in both the midpipes and downpipes — issues that should have been caught by the previous shop. The work was completed a couple of months ago, but I intentionally waited to leave a review until I had time to drive the car and review logs with my tuner. After multiple logs and thorough review, I can confidently say the car is now running properly and reliably. Thanks, Dan, for the fair pricing and thorough, holistic approach to the repair. I highly recommend Zealous to anyone looking for a shop that is detail-oriented, transparent, and reasonably priced.

  Dan has always done a great job on my 2006 M5 to include suspension, pulleys, tune and rear end. Charges a fair rate, way below dealer and backs his work 100%.
