The owner's manual suggests that the 30K, 45K, 60K etc. mile services be performed at Porsche dealerships to receive the approved stamp in the owner's manual that supposedly preserves the value of the car. On the surface this looks to me like a scam for dealerships to squeeze money out of Porschephiles. My experience has been that dealer service departments charge anywhere from 25% to 33% more than a qualified independent mechanic for any service work, and their work isn't any better. Can anyone provide any reason how this dealership service stamp is any better than plain old service records and in what way a dealer could provide better or more competent service than a skilled independent Porsche specialist? I'm getting ready to have the 60K service done and I'm inclined to have my trusted Porsche mechanic (ex-dealer mechanic) do this and forego the dealer stamp in my owner's manual.
