if there is any reason the PDC cover will not work with a non PDC car? That is, the cover with PDC will work on a non PDC car, but obviously not vice-versa. It's just that I'd like to have the option of putting it on my next one, just in case it does have PDC. I don't think it matters, but just wanted to make sure there were no hardware issues, etc. Thanks if you can help....
