I can chime in on the daily driving feel part of FF.

I guess the V12 sound is really loud to a point of tiring for some Porschephile standard.  However, this is still a fabulous soulful sound, which no Porsche (currently without a V12 or V10) can offer.

I could feel the immediate changes in the magnetic suspension when switching the manettino to 'Comfort' mode.  

This change from Sport to Comfort is much more obvious and effective when compared to the Panamera Turbo, in terms of absorbing road shocks and how the car rides over the bumps.  

I almost signed the contract after the test drive and still thinking about the car a few days after the test drive.  The only sane part of my brain (whatever is left over after the heart pounding engine noise) is stopping me.
