I found Modderman Services to be excellent. They found the problem, explained it and proceeded to fix it in a timely fashion. They were friendly and very knowledgeable about my car. I would definitely recommend this shop to others who need work done on their Porsche.

Tire replacement and alignment went fine. No price shock this time. I was surprised to find that the tire sidewalls had mold release (white residue) and the rims had a number of marks (not permanent luckily) from the tire replacement. For a $2000 tire change I would have hoped the sidewalls and rims would have been cleaned.

Excellent service, honest, friendly and reasonably priced. Experts in Porsche service. Will continue to have them do all of the service on my Porsche. Dave, the owner, is excellent all the way around and Steve does an excellent job as well. These guys were referred to me by the Porsche Club of America, Loma Prieta Region. Thank you!!!

I wish I had gone to Modderman Services earlier. Excellent service! Dave was nice enough to stay open a bit past 6pm for me to pick up my car.

I own a '89 944 NA with 150K miles on it and when it came time to replace the clutch I knew I could trust Dave and his crew. They previously replaced the water pump and timing belt and had me back on the road in no time. In the 3 years I have been in the Bay Area they have always taken great care of my car. If you value your Porsche then you are in good hands with Modderman Services, I have the receipts to prove it.

Had my 911 (model 997) in for repair (very unhealthy engine noise). Modderman diagnosed it promptly as a worn-out water pump, very much to my relief since I suspected worse. They quickly made the repair. In and out in a day, problem gone. Went on a long trip the next day with no problems. Great job!

I was completely satisfied with the service and friendly reception I received at Modderman . I would recommend this shop for it's friendly, honest and professional approach to it's customers. Harry Waight Los Altos
