Right, but looking at those answers there is one plate you'd try first.
I don't know how plates work in the US but in the UK quite often you'll find similar cars with similar plates because they were registered at the dealer in a block. A great example is how about 14 years ago nearly all the police cars in Scotland were silver Ford Focuses with plates that started "SF58" and then had more-or-less sequential runs of three letters. "SF" means it was registered in Edinburgh, "58" means September 2008, and the three letter group is serially assigned. Of course, this applied to all their *unmarked* cars, too...
Plates work very differently on older cars in the US because a car gets a new plate whenever it changes owners or the owner moves from one state to another.
