The Porsche OEM cover is a high quality cover that fits like a glove. Used it on my 2 month when away on vacation and the CS was immaculate when I got home.
Cost? I see prices @ around $250 close the the cost of the OEM cover. If you found a better price please post link.I have the Covercraft fleeced full cotton cover. It's fantastic for indoor use. It's super soft, and it's done a great job of not scratching the car, even if the car was not perfectly clean.
