Abstract: A theft resistance car cover to shield the roof and windows from sun, ice and snow comprising a cover having a size corresponding to vehicle outer surface. Rear notch lock straps with one end free and the other end attached to the cover, attach the rear of the cover to the joint between the trunk lid and the vehicle body. These straps contain semi-rigid cores located perpendicularly within the straps so cores cannot pass through the joint.Front wedge notch straps with one end free and the other end attached to the front corners of the cover attach the cover to the joint between the doors and the vehicle body. These straps contain semi-rigid wedge shaped cores located perpendicularly within the straps so that front wedge lock straps can be secured in the joint and not allow the straps to slip within the joint.The cover contains slits in the perpendicular direction from the side window edge of the cover so that the doors can be opened. These slits have zippers to fasten them.
