I think what you are trying to say, Gayle, is that the land was never actually designated a car park by the local authority and it is unlikely to be marked as a car park on any maps of the area. However, insofar as the land has not been tarmaced over and tarted up does not render it's name any different from its usage; if it is used as a car park, then that is what it is.
