If you have driven both and can't decide go for the BMW due to the better service deal. Personally I would go for the Panamera since for me there is no comparison driving them back to back. The Porsche wins by a mile in my books due to superior driving dynamics even if the steering isn't perfect and I'm one of the few that really like the looks of the P car. I'm in Italy now and saw two black Panameras in front of an official building in Naples closely guarded by the drivers and they stand out much more than the many mercs and bmws.
