2012 Cayenne S 120K service - how much and what's done?
 

My local Porsche dealer says the 120K service is $2,500 and includes spark plugs, oil change, and other basics. Seems pretty expensive.

Anyone have details on what is recommended and how much it should cost? I'm out in the Hamptons and would consider bringing it to a non-porsche service center if I could find one that knows their stuff. Any recommendations?
