I found some decent ones from empire. This cover was a replacement cover for a custom cover that cost three times as much and started leaking water and collecting dust under the cover in less than a year. My Empire cover is 4 months old, has survived numerous strong thunderstorms and seering Texas sun, and so far is exceeding my expectations. I have 3 cars under cover, soon the other two will be covered by Empire.
