i was quoted 130 and 165 from 2 diff places for all but windscreen.
the legal level of tint allowed has to allow 75% light through, so if you get this all round you may as well just burn your money as you wont really notice it, you would be much better off, imo, getting the door glass tinted darker, and putting your windows down whenever you see a police car. or just hope they arent bothered (which is unlikely)
