When you do wrap your car up,,A'la Buttercup,,,dont tuck the cover behind the wheels!!!
As any rain will then run down the inside of the wheel onto the disc,caliper,pads and may even work its way into the bearings!!!
And if it then freezes!!!
When I went to NZ for a month,and as it was left outside I wrapped it up and put some 18"sq boards over the wheels and secured the cover around them.
