Hydramatic, radio and vent shades were definitely options that were not standard on '53 Kaiser Manhattans, but you saw them on a lot of them. From what I recall, the Manhattan had the wide rub moulding around the bottom whereas the Carolina had none and the Deluxe had the thin strip. Also the Manhattan had bamboo vinyl interior and chrome strips on the door panels as standard equipment. A lot of them, but not all, were tutoned.
