Ordering WeatherTech molded floor protectors for my new 2013 Equinox. I could order a kit that includes side window deflectors. I haven't seen a "Nox" in my area equipped with them. Are they not worth it, don't work, etc? I HAVE seen bug deflectors on a few Nox's. Any good? I have 6 weeks before delivery so I have time to figure this out.
