DO NOT buy a wal mart cover ( "budge" ). especially if the car is going to be outside. i had a walmart special on my rio red 95 and i keep mine under a car port. The inside of the cover is not soft enough for the paint and if a consistant decent amount of wind lasts, it will scratch the pee-wassie out of your paint. you will either have to buff it out or use an abrasive wax/polish, then re-wax
i just bought a Wolf evolution 4 custom fit cover ( directly from wolf but summit has them ). it is a layered covered and the rep i spoke with at Wolf said it will not scratch my paint. its water resistant but still breathable and blocks UV rays. it will help with the pollen. so far i have not found any scratches but the wind has not gotten very gusty either. only drawback is the $140ish price tag.
i believe i will still take it off the car when expecting strong winds or a storm.
