A mahoosive number plate on the front of some sports cars looks awful - in fact there's no sensible place to put it on some. It spoils the rather beautiful line... So I can understand why smaller plates, on occasion, are better than having the first chapter of Nicholas Nickleby on your bumper.
Rear plates are a slightly different story.... Although I have fitted fractionally smaller ones to some of my cars to fit in the space provided by the designers.
