I saw this car in my parking lot at the office that looks basically like my car I put in another post. The backs and quarter glass looks like 15% not 5%, but I digress. The brow is not as big as mine either (1/2 the windshield). I quickly took some pics before someone accused me of wanting to hijack it lol. It was parked against the wall so these were the only pics I could get in 10 seconds.
There was a malibu I saw awhile back that did the back little windows like that as well. Must be personal preference or something.
