I have no garage space for my project Z3, so it lives outside. This top is compact and allows me to quickly remove it and throw it in the trunk without having to disassemble an entire car cover. Despite living in the Pacific Northwest, this top has kept my car dry inside for 5 straight years of parking outside in rain, snow, under summer sap, and through huge wind storms. The only thing that finally killed my first top was the damn crows pecking at it! I immediately bought another, and will continue to buy any car top products from NA Custom Covers.
