how do I store my M3?

[b1x]

Hey all,

So I recently bought an X5 so that I can drive my M3 as more of a pleasure/2cnd vehicle.
I'm currently storing it in my garage at home (non heated)
I have not done anything to prep it for storage other than detail it, and jack it up and sit it on styrofoam.

I jacked up the car and sat it back down on styrofoam to hopefully avoind flat spots.

should I do anything else?????

thanks all!

ps, I live in Toronto so temp is below zero for a good few months
