Good Car Cover

Hi everyone. Well, i'm onto my 3rd car cover. The first one was a cheapy from Walmart and ripped quickly. The 2nd was a black and red cover from Corvette Cover. Cost about $249 but faded about a week later and returned. The one I have now was about $99 from Amazon but is starting to tear. Why do car covers only have grommets in the center of the car but not in the front or the back? When I just tie the middle, the wind blows the front and the back off. The tearing of the 3rd and current one was actually caused by a tarp clip that held firmly but the cover ripped around the clip. What car cover has grommets in the front, middle, and back? Does anyone have any ideas in keeping my car cover on from the wind? Thanks, Ed.
