Need a Car Canopy

[Newlin]

I'm not sure if this is the right place for this topic but at the moment we have a two car garage which has my mom's van and my sister's Neon in it, leaving my Alero out in the cold. However my mom offered to buy a canopy to help protect it during the upcoming winter, and probably all year around as well.

I have been looking around online and it looks as though most range in the $300 - $500 area but I don't know if these would hold up well to the wind, snow, and ice. Do you guys have any recommendation that are still relatively inexpensive?
