Why Porsche owners choose us over the dealer
Diagnosis before parts
We find the actual cause first. Most complex diagnostics and second opinions are resolved in 1 to 3 hours, which costs less than replacing parts on a guess.
OEM or equal quality parts
We prefer genuine OEM parts, or parts that match their quality, along with factory spec fluids, so every repair goes right and lasts.
Photos and video of everything
Every visit includes a free 200+ point digital inspection with photos and video sent to your phone, so you see what we see.
24 month / 24,000 mile warranty
Our workmanship warranty covers most repairs. Ask us about the details for your job.

Porsche service FAQ
Will servicing my Porsche here affect the factory warranty?
No. You can have maintenance done at any qualified independent shop. We follow the factory schedule, use OEM parts and fluids, and document every visit. Every maintenance and repair visit is also reported to CARFAX, so your service history stays complete for resale, just like a dealer.
Can you get my Porsche ready for track days?
Yes. Brake fluid, pads, alignments and a thorough inspection before the season are all part of what we do.
