Dealer cannot force you to get work done there under threat of losing warranty coverage - federal law prohibits that (Maguson-Moss Warranty Act if they give you any lip). But they CAN refuse extra goodwill if you don't play the game.

Do check with an ind. shop. Then go talk to the service mgr. and tell him the lower prices, and ask him for an itemized list of what they do beyond oil & filter. They probably have one with a bunch of BS on it ...

Next, tell them you want to watch them service the car. See how that grabs them. When they say ins. won't allow - ask why they do not have a window for customer's to watch their LUXURY cars get the high quality service the cars deserve. You can then complain on up the line, secure in the knowledge that you are performing a public service for all Porsche owners of new cars.

Next, leave a GPS device in the car maybe an iPhone set to also record video. This will tell you when they move it into the service bay and how long it stays there.

Finally, you can stake out their service lot with a video camera and then raise hell i the press, Yelp, etc.

This will make you real popular with the dealer.
