If it were me I'd tape up the back window using gafer tape & builders polythene & park it up for a bit, back it up the drive so no one can see the back window

& drive round in the blue one while you take stock, think of it like this that could happen to any car.
If you do decide to get rid then as others have said don't sell for scrap your'll get penny's for it, & as you've stated you mot is up in a few days so park it till the weather starts to pickup as your'll sell it better then & for a bit more cash (take the battery off & put somewhere inside so the cold dosn't kill it).
All the best & hope you have a better new year
