Modderman changed the timing belt on our 944, replaced the clutch hydraulic slave cylinder and as a bonus solved an issue with the complex sunroof that didn't want to latch. Dave showed me the removed parts and made sure I was happy with the work performed. The car has been great to drive since then. I plan to bring in my 911 next- very happy to have such an experienced and helpful shop team in the bay area.

Dave and his team are excellent! Great service, knowledgeable and helpful. If you need a Porsche specialist they are your guys.

My 1985 Porsche 944 timing belt was replaced perfectly and the team at Modderman even sorted out the malfunctioning sunroof for me. True experts!

Worked with David and the experience was awesome. He quickly took care of the interval service I was scheduled for, we added a front brake job once he looked at them and to my delight he told me some of the parts that were scheduled for replacement didn't need to be replaced yet. I just moved to the area and this is my first interaction, but very impressed overall.

Outstanding service, communication and professionalism. I'm a first time customer and will most definitely be back and recommend Modderman's team to anyone.

I have been a customer for the past 13 years. Dave and his crew are the best.

The crew at Modderman is outstanding. I have a GT3 and there guys are experts with that car.

Great service as always!!
