My concern would be for all of the various setting like steering stops, window positions etc, etc... With no power for 'months' I would believe all of these and possibly others may be lost. These cars have so many settings controlled and maintained by computer modules, I would suggest that you confirm this with the Porsche dealer service team.I have a battery question that is a bit off topic but i think you guys can answer it... I'm planning to store my '15 CGTS over the winter and my storage area does not have electrical power. Can i remove the battery and keep it on a maintainer in my basement for several months? I think the battery will be fine; i'm wondering about the car...
