I live in Vermont and I own both a black 2008 Mazda5 Sport AT and a pearl white 2012 Mazda5 Sport AT. Both of these I had tinted. By law, the shop was only allowed to do 50% tint if I wanted it on all side and rear windows. Or they could do 15% limo tint on the back-side and rear windows if I left the front-side windows un-tinted...so that's what I did. It looks incredibly sharp, especially on the white car. It really makes a difference for the kids riding in the rear to have the windows tinted that dark. Just like Secondtyme said though, it is a bit tough to see when backing up at night. Seems like a backup cam and mirror monitor is in my future...at least for the 2012 that I'm driving.
