IMO, it looks like crap to have some tinted, others not, especially on a 4-door where you do the back windows. If you are curious as to how it would look, check out every minivan, extended cab pickup, and SUV on the street. Almost all have factory tinted glass in the rear and nothing on the front. My wife's pickup had that, and it took me one week to get the front
two front windows tinted, which is illegal in Michigan as well. In 60k miles, 3.5 years never been pulled over in that truck (knock on wood).
I had my SVT tinted al lthe way around, but lighter 35% which didn't cuase any issues in 25k miles either.
