I feel confident that Dave aims to provide excellent quality service. He suggests only what is needed to maintain the reliability and joy of ownership for the classic cars he services.

top notch service with a smile!

Outstanding service. My first using their service and will continue. Would strongly recommend to any Porsche owner.

Dave and team at Modderman were great. I had an unexpected service light and needed my breaks done. They cleared the issue and replaced the brakes and rotors. The delivered the car on time and met every expectation. I would highly recommend Modderman

Always great service and I really value their in-depth knowledge of Porsche cars. I appreciate the drop off and pick up at my house.

Modderman Services were friendly, communicative, accurate and on time. They are my go-to shop.

David, He is great and the service and personality makes me feel like I am at home relaxing knowing that my daughter's car is in good hands. The staff very friendly and very fast on response with questions I stopped going to the dealer sense I met David he will actually do what he says on your vehicle and very well priced. David thank you again GO SJSHARKs

Amazing customer service. Highly trained and courteous staff. Hands down the best Porsche service in the Bay Area!

Dave has a deep knowledge of Porsches and it is evident as you walk into his shop. I like his professionalism and great customer-centric attitude. Highly recommend him.

My father took his vehicles to get serviced there back in the late 80's, early 90's. Fast forward to today, I now take mine, and it is still, excellent service. I would recommend them to anyone.
