I was gifted a non-running Porsche 944 and without any previous automotive knowledge I decided to dive in and see if I could get it back on the road. For the last two years I have been wrenching and when I have run into roadblocks, Dave Modderman and his crew have been an indispensable resource on my journey in getting my 944 up and running. Without his knowledge and sincerity, I would not be as far along as I am today. He is humble and understands what it's like to be learning automotive repair. His passion for cars shows! He has integrity and I'd recommend his services to anyone who owns a Porsche.

Excellent service. Reasonable. Strong on preventative maintenance.

Have taken my 987 to Dave a few times and I have been very satisfied with my experiences so far. Their work is high quality, highly recommend for anyone that owns a Porsche.

Dave and team are as professional as it gets. Fast service with true and accurate assessment of what is needed. Team is extremely knowledgeable. The only place I would recommend your work to be done regardless of the age of a Porsche.

I first visited Modderman in 2015 after my 2001 996 developed an odd intermittent squeaking sound. I had already taken my car to a local dealer and two independent shops where I paid a lot of money for them to replace parts that weren't broken. At my wit's end, a friend recommended I try Modderman. Dave made it his personal mission to get to the bottom of my issue. A week later, he had solved my issue and I was shocked to learn that his total bill was less than I'd paid any of the other shops who failed to fix the problem. I have been taking my car to Modderman ever since. If you own a Porsche and find yourself in need of service, repairs, or performance enhancements, I strongly recommend you check out Modderman. Dave and his entire staff are true artisans who take pride in their work. Whether it's an oil change or debugging some elusive intermittent quirk, Modderman will get the job done at a fair price.
