I have a Silver and Onyx 2000 S4. I don't know about anyone else but I hate the dirt or dust that is so easily seen because of the dark interior. Using a wet paper towel picks up some dirt, vacuuming is time consuming, but these grab it wipes do the job greatly. It picks up every spec of dirt and leaves nothing behind. They are like dry baby wipes, that leave your dusty, dark interior spotless.
