We actually had this conversation already when I was looking to purchase them for my white car( but mods probably see so many posts they tend to blend together). The in channel ones don't fit on our cars for some reason. I think it may have to do with the angles, but probably why weathertech doesn't make them for our vehicles. I tried two sets of the and they just fall out. I like them more for the sun blocking properties they have. They do go down a little bit without getting rain inside, but I'm not using them because I smoke or anything, so the tiny bit of fresh air they let in is fine. Plus with my blue car I have a moonroof now so yay!
