Edgington, they sell static cling 5% limo tint you could slap on the windows to help prevent light from entering/people seeing inside. I have my dome lights turned off when the doors open, so only the lights on my doors come on when a door is opened...i hate lights coming on when i open my doors at any time. Auto locking doors? mine doesnt do that...do you have an aftermarket alarm? Vertical room to get nasty...just use the 2nd row before you fold the seats down, i havent had problems there.
