I came across this German license plate of which I really don't know where it comes from. It has 4 signs, consisting of 3 letters and 1 number. See picture beneath:
I don't have to know from what region it comes (privacy for the car owner) but really want to know if this is just a common license plate or a special one. I'm used to 6 symbols on a (European) license plate, 4 seems really uncommon for me.
