Put the car in your garage, hang the keys up, grab them in the spring and go drive your car. A car sitting for 3-4 months is not going to do anything to it. The "WORST" thing that "might" happen is your battery is drained, but even that is unlikely. If you are worried about it, put a battery tender on the battery.
Today's chemicals, engines, fluids, tires, etc are all substantially better than they were 30+ years ago when people came up with these "storage" methods. For cars today, there just wastes of money and time.
Storing a car is putting it away for years, not a couple months.
