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.

Always fantastic service. I take all my cars to Modderman, not just my 911.

Dave and staff are always professional, friendly, and welcoming. They do great work and always meet my schedule needs.

As always, great and prompt service. They call with any issues or just to let you know status.

As always we are satisfied with the quick response and repairs that were performed at last minute.... Our passenger side window was stuck at half open and would not close . Dave instructed me to bring it in to diagnose the issue. He contacted me back later that same day and told me the problem was with the window regulator and said he would get right on it for repairs ! I was so relieved from his quick response and prompt service.......This is a very clean and professional shop and I will continue to take our Porsche 997 back with all my repair needs ! Thank you Dave
