jeez if its just for the winter, change the oil, put good gas in it (maybe some stabil).
THen just park the thing inside with a cover on it.
Thats all I do.
Yank the battery and put it in the house on a piece of wood, so it doesn’t sit directly on the ground.
I clean the car real good and put boxes of baking soda to absorb any smells.
Put the climate control on vent.
