i went and got mine done at tnt tinting and they charged me $170 for all my windows except the windshield. got a lifetime warrenty against scratches, bubblin, peelin. anything and they will replace it for free. ive got a zx5 so thats 6 windows for me.
For my rear windshield as well as the back two windows (+plus the 2 small windows) of my SVTzx5 cost me 150 for 5% tint (as in only 5 percent of light gets through). its actually darker the the limo tint we use @ the limo company i work for. www.empireint.com
sorry forgot to mention the lifetime warranty that comes w/ that tinting
