Re: good grief
Part of UK number plates are for identifying the region and this has always been the case.
Currently its the first 2 letters ie HW for Hampshire and the Isle of Wight registered vehicle
Under the previous format it was the last 3 letters - WDL for an Isle of Wight registered vehicle.
Apropos of nothing cars with the WDL suffix used to carry a premium with used car dealers as it was assumed they would be low mileage and well looked after.
