Joking aside, it shouldn't come to the new owner wrapped in anything; after PDI (Pre Delivery Inspection) it ought to be just all gleaming, shiny paintwork with no sign of clingfilm, thick wax or any other "protective" matériels.
N.B. take a tip from those of us who've already been there, do a thorough visual inspection inside and out, check everything works and twiddle (ooer) all the controls before you drive away. Saves disappointment and hassle later...
