Update on Swift
It now has tinted glasses. The car came with some kind of tinted glasses as the manual claims. But, the AC is not really efficient to cool with the transparent glasses.
Of course, the real dark films would get you a challan. I am playing really safe here as I went for the film Maruti Dealer recommended. Made by 3M, it comes with a 1-year warranty and cost around 4 times the rate of regular films.
Confusingly, the law states that a legit film would be at max 50% transparent. However, the recent press statements made by the Delhi government say that the windows on the car should be totally transparent.
Very confusing.
