Yeah, I bought what they call a "garage". I won't be parking mine in the sun for any length of time so the dash should stay fine. Most modern dash materials are made to take considerable heat and UV but I won't push it. A dash mat is like doilies on your couch or runners on your carpet. If you want plastic covered carpet, buy plastic carpet. Or better yet, buy a cover. I have one even for my garage. I cringe every time my kids and their friends walk by my Challenger.
