Although I think you're asking about the looks of certain window tints, I wanted to point out that if you paid for ceramic-based tint, there isn't a big change in heat reduction between the levels. Go here and click on the chart to read the values. I have this on my Camaro and like it much better than the cheaper dyed tint on my GN, plus it makes it easier to drive at night w/o having to go too dark of a tint.
