I have a classic car. We live in Ireland. We are retired and sold our house to move into a smaller one. Our current home does not have a garage, nor room for one. I rented space in a parking garage, but the owner moved out. The car now has to stay outside. A "Stormforce" cover was the solution. It is fully breathable and totally weatherproof. The car is under the cover with an electric dehumidifier inside. The car remains dry, inside and out. We are now coming to the end of life of its second cover. After 3 years it starts to delaminate and loses much of its protective ability. This is the only reason why I gave it a rating of four, but about £ 350 every 3 years is actually very good value. The car has not deteriorated over the past 6 years. I will need to contact CoverZone for a new one before the end of the year.
