Last night in my daily driver I passed a gritting truck covering one of the local roads. Time to hibernate my z4m 
Does anyone else hibernate their car over winter? Do you sit in it every so often with the engine running so the battery doesnt go flat? Or maybe leave it plugged in to some trickle charger? If its permanently plugged in do you just have a power extension hanging out the window of your house? Maybe I need to install an outdoors wall socket.
