I needed one for the trip to Road America in Wisconsin! As we left from Ga. I was afraid the weather would catch us. I picked one up at PEP Boys for $99. Water resistant, soft liner. Stopped in Chattanooga for the night . The next morning there were reports of rain within the route we were taking. Put the cover on the car secured it with the strap that was provided and got some bungy cord straps with hooks on each end from Harbor Freight. Secured two hooks mid way up the fenders, front and rear, to undercarriage of the car. I used them to take up the small amount of slack that the cover had. I used aproximately10 of them. I chose the cover that was equal to the lenght of the car(they were sold that way). I put the cruise control on 60 and let it go. The cover developed a bubble toward the front of the car(trailered with the rear in front) that barely and rarely setup a flap. The cover had a soft liner that didnot harm the paint. In Kentucky we ran into the rain that was soooo heavy we could not see 20 feet infront of the car. Had my wife watching for the white line on the shoulder of the road. Couldn't stop due to those behind me would have never seen me. Kept the cover on till in Illinois when the sun popped back out. Upon removal there were two small vertical tears of 2-3 inches in the cover. Same spot on both sides. This was about 6 hours of travel with the cover on! The hooks were run in and out so that they did not face the paint. Tears were not at the anchor points. Worked well for the intended purpose. No marks on the car.
