Can not answer what is the best car cover but I will be the first to say.
Best thing for your car is no cover. This is the best defense against moisture.
Very true...plastic would be a bad idea for long term storage. More than 3-4 daysat a time.
A good car cover breathes and beads water like magic, That red cover above in my pictures does both really well. The water runs off of it like it was plastic and it breaths really well. It fits so good I would be surprised to see it blown off. After 2 years of use the wife's GT is still flawless paint wise.
