Here's what we did
Did not use stabil, drove car onto wood pieces on top of plastic, to keep moisture from wicking up through the concrete, mothballs on the floor and dryer sheets inside the car, fresh oil change, wash and wax, custom car cover, left the doors 3/4 latched as not to compress the gaskets, and put a battery maintainer so it won't have to be started. We live in Minnesota so understand the cold issue. The dealer told us not to use stabil under a 6 mo storage period. We heard that starting the car could put too much moisture into the engine and exhaust.
