On that note, I am very fond of the $7 accordian-folding, bubble-wrap, foil sun shields you can get at Wal*Mart. Easy to pop up, stays in place with help from the sun visors, stows away easily...and truly does drop the inside temps of the BMW and Passat by at least 30-40 degrees. It's remarkable how much cooler (or "less blazing" at least) those things can make the car...
