RC - I feel your pain. This is a real 'what would Jesus do' situation.
In the US we have an expression you reminded me of. 'Kiss me if you are going to f*ck me.' Since I know German I know that could translate well - :-)
Can't wait to see pictures. Too bad that you are at their mercy because of the registration and they are taking advantage of that, I would have simply canceled the order (not for real, but as a bluff - to get a better kiss with the f*cking).
I am surprised the someone at Porsche has not read this thread and ran a few bells!!! (They also don't seem to hear me complain about my lousy dealer - Aristocrat (that is Merriam, KS!))
Cheers and best of luck!
