Is there a quality difference between the two? I know everybody hates them, but I want one for the winter months. I had one on my old car and it stopped the stone chips.

 

I got mine for the same reason.
There sure is a difference. There are 3 levels Le bra, FOx and Covercraft. The main differenc is in the backing material. The covercraft has a lot nicer, softer backing, Also the covercraft has mesh over the nostrols on the firebird and mesh over the fogs lights on the trans-am and camaro model. This is key to keep rocks from getting underneith the cover (the main reason people hate the covers)
