Windows are all that "solar glass" type they say is tinted, but it is not really so if you see that it is just normal glass designed to reflect heat. Might be super minimal tint to it but not what you are thinking. There is no option for factory tint. If you want tint then ask the dealer at purchase and they can work it into your price and have you car tinted by their local shop/guy they use. Then it can be financed with the rest of your car. I get every vehicle I get tinted, even though I lease. I also pay out of my own pocket as I know the quality of the tint and can choose exactly what I want (illegal dark 20% all around) so I just pay my own guy.
Last Honda I got (HR-V) the rear windows were tinted from the factory (interesting fact on factory tinted windows; they're really dyed from factory, so no heat rejection properties at all) and I hat them tinted lightly and the front two tinted darker to match so they all the same from inside and out. Looks great! Much, much cooler in the summer too!
