For those of us with kids - although this is not a US model option, I was reading through the PDS manual for the GS F and found there are rear side window shades you can get from Lexus that fully integrate with the car. They're not exactly cheap like going to the baby aisle at Target, but they're designed for our cars and fully cover the window(s). I am looking into acquiring a set of these and will advise when I have them in hand.
Part numbers are:
Right Rear 65960-30041 and 65907-30070-C0
Left Rear 65970-30041 and 65908-30070-C0
The first number is for the small round section at the rear, the second is for the main window. Description is " CFRP COMPOSITE & SUN SHADE-WITH(BACK WINDOW & REAR DOOR WINDOW), BLACK"
I also did some poking into the rear window sunshade. It appears to be able to be installed, and the wiring is there to connect it. Just not sure about the body ECU being programmed to work it. You need to replace the rear deck panels and install the sunshade as well as the switch. The parts are about $2.1k new, so it's a pretty significant gamble to determine if it will work or not even if you're buying junkyard parts.
Shade - 64350-30152-C0
Package Tray Panels - 64330-30C13-C0 and 64340-30161-C1 (for Mark Levinson equipped vehicles)
Switch - 84940-75041
Sunshade Relay - 84940-75041
Last but not least, I did the homework on the wiring harness for the trunk closer. The wiring is there. The parts to implement are again, not at all inexpensive, but at least if you buy the parts, the wires and connectors are present. I have not fully priced this out, but it again will be well over $1k for new parts.
