i had 15% on my car and got hassled a couple times, but it was all from the menomonee falls/germantown cops. none of them gave me a ticket for it though. basically just a reason to pull me over and hassle me in case they find something else.
realistically i am going to go with 35% on my new car. the 15% was awesome and intensely cave-like, but it's pretty dark in all reality. people claim up and down about awesome deals they get, but DO NOT CHEAP OUT. good tint is good tint, no matter how you put it.
ramon...i want my car tinted...i text you...
