IMHO, the silver roll up sunshades, as used in light aircraft, biz jets, are the hot ticket, or in this case the cool ticket, at least in Texas. I have been using one on my truck for 140k miles of the 240k that it has, and not only is the dash in great shape, but it really seems to have helped the seats, carpet, etc along. Not to mention, if you don't park the car into the sun, with a sunshade, and at least one window cracked, your asking for trouble in Texas.
