The smart charger idea is important. I had one on my Cayman S when in winter storage and it only charges the battery when it starts to loose charge otherwise it turns itself off. Another idea someone in the Cayman Club had suggested (and I used) was to put squares of carpet under each tire; it protects against excess moisture creeping into the car.
