Made from tough polyethylene vinyl acetate GP-91055, this breathable, waterproof Silverline cover is designed to fit and protect extra large-sized cars. It has elasticised corners to ensure it stays in place, even in windy weather. When it isn’t in use, the cover folds up neatly to a compact size so that it can be conveniently stored in the boot of the car--or even behind the driver’s seat--with no hassles
