1998 Porsche Boxster - Seeking vcar cover advice for outdoor storage

Hi what is the best out door car cover to put over my old Porsche Boxster in the UK. Thank you.

Soft fabric inside, waterproof outside, vented, straps to secure it.
Easy to put on and remove, if it is not relatively easy, you might only use it once.

I’d find folks in your area that are storing cars outdoors, and see what works for them. Cool damp weather/high humidity is a breeding ground for mold and mildew in the interior of your car, to be avoided.
