Moi aussi.  Spent a lot of time last week sitting in all sorts of new Panameras and 997s.  The 997 interior looks very dated compared to the Panamera interior.  The new 991 interior will be vastly better, IMHO.

The sales manager of the dealership--a major one in Florida--says that the Panamera is his biggest seller by far.  He is selling 997s, but mostly nice used ones. 

Incidentally, he had a beautiful black/black GTS Cab on the floor.  The price was in the Panamera Turbo range....
