But see, isn't this true everywhere? This is why I am confused when people say "oh, well that car is a 1991 model becuase the plate starts with J4Q" I seriously doubt that someone kept the same plate from the day they bought the car all the way until now. In some instances, people are even forced to changed their pates.
A good example of this is right here in Michigan. About a year ago in '06 or '07 (I forget which) all vehicles registered (old and new) were given completely new pates when it was time for their yearly registration renewal. This was done in order to introduce a new style of plate that reflected better, but unfortunately it is quite a bit more ugly too. Anyway, the point is every single plate on all the cars in Michigan is no older than 2006, even though the majority of the cars are. And no, the plates are not of a differnt style but have the same numbers, they are completly new in the number and letter regard too, so there is no correlation between the old in the new in terms of identifying them, in case you were wondering.
