O BTW, in mass. the legal tint limit is more for inspection hassles really. The reason it's illegal is cuz cops argue they can't see in the windows when approaching the car if they have to stop you, you could be pointing a gun at their face and they wouldn't know it. BUT, all you need to do then is always roll the windows down when you get pulled over, which is what I do (plus I have special cop-friendly stickers hehee) It is a hassle to get an inspection sticker though once they're done, that's why I go to gas stations where I know the dude.
