haha u will not be happy with that 5% on the back at night! lol insted of normally backing up, your going to have to pull an Ace Ventura and hang ur head out of the window to see...
my sis had an 01 Monte Carlo with 5% all the way around, it sucked...
I have 35% all the way around, 5% on sunroof and 5% on strip...windows could be SLIGHTLY darker but i'm happy.
It'll be dark, but I want it so you can't see inside the car through the back window at all, with 20% you can see through it because of the windshield reflecting through it.
