I would definitely recommend Modderman. I brought in a 1996 911 with various issues, and they quickly diagnosed and fixed the problems. They also provided great service.

Dave is the man. My Porsche’s battery was dead, and he hopped on the phone with me while he was at a party and walked me through the process of opening the front trunk and jumping it when there was no power. Highly recommend

The transmission on my VW Golf was reporting Emergency Mode. I took it to another shop that recommended a replacement transmission. Dave and his crew found an electrical fault that only needed a $90 part.

The place to go for independent Porsche service in the Bay Area 👌🏼

Dave and the team at Modderman have worked on a number of different vehicles for us, the service has always been professional, efficient and well priced. Modderman is our goto place for Porsche maintenance.

Dave and his staff are great, and the range of Porsche cars they service and repair is everything since 1953! A great shop that I will rely on.

I finally took my 2015 981 Porsche Boxster S to an Indy Shop for work outside my skill scope and Porsche dealer maintenance. I am very happy with Modderman with the PDK and gears set differential fluid change. David even told me I didn’t need a new oil pan with its built in oil filter as I had only 22,700 miles on it and it was very clean still. I am very picky where and who performs on my Porsche and David made feel at easy after talking to him and asking a few questions. The whole personnel is very professional, polite and really listens to you. And Modderman did it at a fraction of Porsche Dealers price. There is no doubt about it, when ever I’ll need any work done on my Porsche that I can’t do myself I’ll be calling Modderman! Thank you for a job well done!
