One question and it has puzzled me for a few years.
I note you say the car has darker rear windows
I'm aware that the front glass and front side windows cannot be that dark due to the driver not being able to see out the car properly.
Loads of cars have darker back and rear door windows which to me always look pretty messy but what is the great advantage to having the darkened glass do people realy not want others to see them in the car.
Confused!
