Leave it covered in snow?

Or clear it? That is the question.

What is the best thing to do for a car that's snowed in and not going to be used until the snow has gone. Mine is currently covered in about 2ft of snow, and while I was starting it every few days, I've got bored with that and have just left it.

What do you think is best, clear it and keep starting it, or leave it in a nice fluffy insulated blanket of the Artic's finest?

assuming its has antfreeze and there is time and facilities avalable for starting with a flat battery if required i would just run it for 20 mins a week
