Change oil/filter.

Fill gas tank, add STA-BIL, let it run for a bit to circulate it through.

Touch up interior and exterior as needed.

Check tire inflation.

Use CTEK MXS 5.0 battery tender.

Put storage insurance on it ( many lenders have insurance requirements when you put a lien on your car and need to approve if you want to drop collision/liability coverage while it's in storage so be sure to check with your lender. BMW Financial emailed me a letter approving it so I could give it to my insurance company incase they needed it.)

Car gets moved a couple times during the four months as I'll take the wheels off to recoat them, etc.

Dream about spring time....

Your M2 with that S58 engine has an LFP starter battery.
You better switch to a CTEK US lithium charger, or similar for lithium iron phosphate, or…. you’ll ruin your (expensive) battery

The G87 M2 is equipped with an AGM battery.

Ohh I stand corrected.
That’s interesting — wonder why the difference?

1. Filled with non-oxy fuel and added fuel stabilizer and drove it enough to get it into the fuel system.
2. Full wheels off wash and detail. Cleaned wheel wheels, brakes, rotors, brake calipers, wheel barrels, the underside of the hood, engine bay, and glass inside and out, wiped down the interior, vacuumed everything, and stipped the floor mats too.
3. Inflated tires to 45 psi.
4. Put a heavy-duty tarp down on the garage floor to keep moisture from concrete away from underside of the car.
5. Put air desiccant bags in the trunk in a foil pan and in the interior of the car to absorb moisture.
6. Removed the wiper blades and put them in the trunk, put old socks over the end of wiper arms to avoid scratching the glass.
7. Bought Battery Tender @ Costco for $42 with LiPo maintainer setting and attached to the battery.
8. Car is sitting on race ramps (with higher pressure in tires) to help avoid flat spots. I jacked up the car and slid the ramps under the tires instead of driving the car on them since I have the rear of the car about 1" from the back garage wall.
9. Put some steel wool in exhaust tips to keep out mice.
10. Put some glue traps in the garage for mice control along the walls near the car.
11. Put some Irish Spring soap bars on the wheels below the brakes, might be old wives' tales to keep mice away...we will see.
12. Installed soft custom-fit CoverCraft dust cover. Super soft inside and adds some cushion to keep things nice. The car was super clean when I put the cover on and I have no concerns about damage. My car has full Stek ppf too.
13. Set the thermostat in the garage to 50 degrees.
14. Dehumidifier set to 50% humidity. Runs a lot and pulls some moisture but not as well as when it is warmer. May consider raising the temp in the garage to 60 but only if that drys the other cars completely overnight or lower to about 34 to keep ice from melting fast on other cars).
15. Other cars are parked on moisture containment mats too.
16. Put a heavy rubber curb stop on the moisture mat to keep my wife from getting to close the hibernating car (she parks in front of the car as her Subie is not as long as my daily/winter car).

Now I just need to wait until April for the snow to melt and get salt off the roads.

Edit:

1. I also added some air in the tires every 4-6 weeks to maintain the higher tire pressures.
2. Not sure if the soap bars worked, no sign of mice or mice in glue traps.

Good joke 😃 in Russia we are driving with mices all winter long. Since 1991 we wearing winter tires.
