Car covers don't last

What's a car cover?
lol
Honestly, i doubt that i would ever buy one, my cars are a bit junky and that's the way i like them.........
Back to the O.P., i have learned that you get what you pay for, and that's not just car covers.
Decide what brand suits your needs and shop around for the best price.
Basically, buy the best item within your budget and live with it.
