I got 5% limo on all 4 windows plus the rear window and front windshield. Only set me back $110. Down here in FL if you know where to go, prices are cheap. However, the range from $80-300 depending on where you go and what kinda tint you want done.
Usually it's a little over $100 for a basic dark tint job though. However I have seen some cars that have like etched designs or something on their windows and that is what jacks the price up.
Anyway, the cops down here aren't too bad about the tint law. Granted though there are those cops that always pull people over!
FYI, I used to have 35% on all windows and 2% on the sides. Talk about dark, you couldn't even see out. LOL.
