yeah, that is very possible to check - i copied down al the details from my original compliance plate - the jap 1 -and called up some nissan dealer - cant remember which one, and they give u build date, as well as color, trans etc. should be more than enough info for u.
and i think it would be a major pain in the ass to change front lights, bonnet, front bar, dash, steering wheel, trim, rear fill panel (between indicators) etc just to trick someone, IMHO....
