Speed and auto parts stores carry many different types of car covers. For out side use obtain a more expensive one for better air ventilation and moisture protection. A less expensive one for inside use. Another way to keep mice out of your car during long storage periods is put moth balls in clam bags and place them in the car, under the seats, under the dash, in the glove compartment, in engine compartment and the trunk. Be sure to leave the tail of the bag out in the open so you can readly find them when you are ready to use the car Clam bags can be bought in supermarkets in the fish dept.
