Query: Not satisfied

The car cover resulted to be way too big for a Mazda Miata. The material doesn't seems to be waterproof. Also the cover should come with some kind of fasteners to clip it to the car and they were not included as it was promised in the product description ("Includes non-scratch tie-down grommets, rope and handy storage bag") nothing was included.
