I have been a porsche driver for over 20 years. I have never had tinted windows, and thought that was for Ferrari drivers and Corvettes.
But last year I went to help one of my buddies who was helping out with a Subaru WRX. Anyway, we were futzing around and another one of his friends stops buy with a 996s that he just bought and had the windows tinted. I was admiring the car and he says the window tint cost him only $100 and they did not have to remove the windows. I looked through the tint from the inside of the car, and whaddaya know, it does NOT obstruct your vision or look too dark.
I agree with Milt. My Chevy K5 Blazer came with dark ghetto boy tint from the factory in 1988. So, I went and got my windows tinted for the first time in my entire life.
Why? Because on Saturday we had honest-to-goodness 110F degree heat. It will get hotter yet. It will probably reach 115F next month. Around here in central California EVERYONE has tinted windows. If I get a ticket, so be it. I'll take the tint off, get the ticket addressed, and then put the tint back on. It is not for the looks, it is for the fact that I am tired of getting blasted by the sun and dealing with the heat. I also stopped caring if people think I'm a wanna be ghetto poser.
