I've been thinking.
FACT 1 - The side windows on a Z are factory tinted to the maximum legal limit, so if you put even the most gentle tinting film onto them you're breaking the law.
FACT 2 - You can sit in the driver's seat of a Z wearing the darkest pair of sunglasses that man can make, look out of the side windows and be doing absolutely nothing illegal.
Where's the logic in that? Is it me that's an a**, or the law?
