Whether you park your expensive or classic car indoors or out, you probably want to provide the best possible protection from dust, water and bird droppings/environmental damage. Florida-based Carcoon sells air-circulation-type (bubble) storage systems for both uses. Each one is designed to reduce the moisture content in the air within the bubble, thus reducing the potential for condensation to form on your prized possession. Carcoon prices start at about $950.
