Here's a question almost everyone here might relate to. Just transferred my license plates from old car to new car and was reminded I just have the screws for the top of each plate. I realize most people don't screw in the bottom of the plates (I suppose it used to be standard but people have gotten lazier/cheaper in this regard). I'm thinking for this spanking new car I might buy the four screws and use them. Question is if having each plate screwed in all four corners preserves the plate longer or is it just an aesthetic thing? Does a metal license plate last longer when secure in all four corners? Since we no longer have to get new plates every year condition does make a difference. Right now I've got the usual dealers' plate holder, which is the usual cheap plastic.
