Philly cops don't care.
I've got 20% and a black interior so i'm pretty dark.
They just hate the mirror tint.

i have 20% mirror with nothing on the back window

I should have done 5% black with no back window

im not really worried about philly, i didnt think they would make a big deal out of it, but i go to school in oxford, PA and the cops around there are waiting for an excuse to pull somebody over..
and a bonneville with tinted windows looks like the perfect car to pull over

Just remember...safety first!

I live in PA, and I have 12% tint all around. I've had no problems yet. As long as you don't drive around like an a** bringing attention to yourself, you'll be fine.

true dat. then again, it depends on the car as well. ive got 35 on the front and 5 on the back of my black bonnie and i havnt had one problem yet. on the other hand, i had the same setup on the my mustang and i got pulled over five times for it in less than six months. had to take it off...

i live in the hood...and in the hood any car that looks like you might be makin a little bit of money is gonna get pulled over, especially if they see the car over and over again....now if i end up getting pulled over for the black tint, i plan on being able to say that i can legally have it on my car....either way im planning on tinting the windows how i want them and then im gonna race a patrol car on the highway!!!
just kidding...

I'd be worried outside of philly too. Esp in jersey. The cops over there will pull you over as soon as they see you don't have a jersey plate in the front. <--corny
I drove through N philly everyday to get to temple too w/ no problems. Theres a ton of bonnies w/ limo tint and 20s that drive around.

Here'* the tint laws by state and province.
