I just wanted to say thanks to Motorwerks Porsche as I just got my 40k service done there, they replaced the spark plugs, the valve lift solenoid (under warranty), did a fuel system cleaning using Terraclean and a brake fluid flush in addition to the normal maintenance items for just $1000 flat and I got a MY13 Cayenne GTS for the time the had my car in the shop

So I can only recommend them for any work you need to be done that you might not be comfortable with doing yourself, which in my case was the spark plugs and solenoid so I decided to let them do everything instead.

 

When I lived in Lake Zurich, Illinois they worked on my 993, great dealer I agree.
