From all the pics I see it doesn't look like any of the windows are tinted. Is anyone planning on, or has anyone already done any aftermarket window tinting on their model S? I was thinking of doing 5% on the rear windows and back seat windows and possibly 15-25% on the front driver and passenger windows. What do you think? It helps keep the sun out, would protect kids from sunburn if I get the rear child seats, protects leather, keeps peering eyes from seeing a huge 17" touchscreen that someone might be tempted to break in and rip it out....
