First, thanks to all for the advice. I want the cover to use on my car whenever it is outside. Most days it is in a covered area but not at night.
I had an MB NOAH for $140 but it was stolen when parked outside during the day!? I will replace with another but perhaps a polycotton if they protect better/last longer/or are in some way a better value. I do not care about dust(unless letting dust scratches the paint) but am more concerned about the paint and interior being baked by the sun and tree detritus at night. I will also lock it on. Not foolproof but better. I liked it well enough but am open to advice.
So MB NOAH for $140 or polycotton for ? What does everyone think?
