Unfortunately, Mississippi just changed their inspection laws this year to where the inspection facility HAS to check the legality of your tint. This meant that I had to go get the tint replaced on my ZX2, since it was 20% all the way around. $270 to get the old tint stripped off and new tint installed. :x
Yes, I liked how the darker tint looked (it really contrasted the bright yellow paint), but it did wonders for keeping the car cool in the summer, and it was also a major help at night too. Truck headlights are right at the right level to be shining into my mirrors, so it kept from being blinded at stoplights.
