Does anyone know if there is a sun shade for that small mini rear window? Since my car sits all day (0600 - 1700, too cheap to drive to go eat out ) in the sun it will either get sun on the mini window at the begining or the end of the day. One time I parked north/south the sun did not hit it and the car seemed a little cooler (only about 90).
If you get a rear sunshade, you could mount it in a way that it'll cover the lower rear window. Other than that, maybe a long piece of styrofoam?
If you order the rear window shades from the Priuschat store they come with small triangle pieces for those little windows.
I have all the shade except for the long rectangular window in the rear of the car. The one that is under the window with the rear wiper.
