No matter what part of the world you live in, in most places, having tinted front windows is illegal. That doesn’t mean you don’t get to see cars having tint on the front windows, but lets just say those guys are willing to pay the price for their insubordination.
That is unless you come up with a solution like this Lada/VAZ owner did and install two windows on each of the front doors, with one of the windows wearing tint and the other left clear. This way you can choose between a law complaint look or a mysterious appearance depending on how you feel or the area where you want to cruise.
