I also live in West Michigan,(Fennville,) bought my 05 limited a year ago August with 6,780 miles.
This will be my second winter, in storage,( my garage, next to the house.)
I had no problem last winter, this year I added a battery tender, a custom cover and mouse traps under the car.
PS my garage is not heated, I start the car once a month for 30 minutes or so, and put the insurance on vacation,( I think we pay $65.00 for comprehensive from November until April.)
Good Luck
