When we bought our Saturn it included a free window tinting from Glamour Glaze. Our windows are powered and the glaze has help up quite well. There hasn't been any peeling or scratching on the Glaze. The tinting also has helped keep the car a little cooler in the hot summer months. I had never thought about having tinting like this put on my car, but in the future I will look into it if it isn't already included in my car.
