Excellent quality work and prices half as much as the dealership. I take both my Cayenne and Panamera here.

I've taken my 2005 997 to Moddermann's shop ever since the factory warranty expired. They always diagnosed problems (e.g. water pump, wheel bearings, exhaust) right the first time, and fixed them at a fair price.

Modderman Services is an outstanding group. Excellent service and they understand their customer base. I have been going to Dave and his team for 4 years, and I would recommend Modderman Services without reservation. I own a 2004 GT3 and am very particular about the work and who does the work on my Porsche. Modderman Services is the right team to work on my car.

I'm glad I learned about Modderman Service when we bought our used Boxster. Dave and his staff really know Porsches and do expert work at reasonable prices. Our Boxster has been very reliable but when it needs service we take it to Modderman.

Excellent.

I always like taking my car into Dave Modderman and crew. I always come away confident in the work, educated, and charmed by the cars in his lot and up on the racs.

The service provided by Modderman Services was excellent. I had a very big problem with my RUF 3800S, which is a Boxster with a 3.8 X51 engine instead of the stock 3.4L engine, and the owner went the extra mile to help resolve the problem. They take fantastic care of my car. Their knowledge of all things Porsche is remarkable. I would recommend Modderman for any Porsche related servicing.

The top on my boxster wouldn't operate. A part in the lift mechanism failed. I called at the end of the day, was scheduled for the next morning and done by noon. Costs, as usual, reasonable.

Great as always. Dave is a pleasure to work with.

Always the best. I have all my cars serviced here, not just my 911.
