Best Sun Shade IMHOgot this on my 2004 Corolla and liked it better than the roll up kind so I ordeed it the same day as I ordered my 2005 Matrix...see I had 6 weeks to get parts and stock up so that is why most of these mods were done in the first 3 days, I had tried and true methods and parts on the Corolla and had 6 weeks to sit and think about my Matrix while it was being built and shipped...anyway check this outit is like a compressed layers of felt and foil see CovercraftPart Number: UV10825Interior Window Cover; UVS100™ Heat Shield; like it way better than the rolled up one both are custom cut but this one seems to do a better job and does not sag...
