I have been very lucky with my tint. I have always had 5% on all windows. But with the VX it came with some stupid mirror tint that I am suprized I have not gotten pulled over for yet. Actually I work with someone who has a 2003 Bonneville (white) that has 5% all around ..including on the winsheild. It looks real good to say the least. Actually it is making me want to do the same when i retint early in the spring.
I was quoted $125 - $150 for the removal at two shops. They said, yeah the windows are minimal but then that also makes it harder and even more they want to be carefull to keep the defroster on the rear. If I was you I would peel all windows but the rear myself. It is very easy you practically can just start picking at a corner and once started it peels very easy. Goo gone is your friend too.
