Abstract: A protective vehicle cover which includes within its design a rotatable retaining element for retaining the protective cover within the trunk of the vehicle so that it is safety stored to prevent theft and further retained within the trunk to thereby eliminate any defacing of the exterior of the vehicle or any impairment of the aerodynamics of the vehicle when the vehicle is in motion. The present invention further relates to a protective vehicle cover which can be draped over the vehicle in a manner by which the protective cover is threaded through the gap between an the top rear of an open trunk lid and the rear upper body of the trunk and thereafter spread over the vehicle while the trunk lid is closed, to thereby provide a protective cover which has a portion extending into the locked trunk so that the vehicle cover cannot be removed or stolen and at the same time provides a complete covering for the vehicle.
