Abstract: A passenger car has a self-supporting body, which has a roof opening. The roof opening is outwardly delimited in the vehicle transverse direction by lateral roof rails of the body and in the vehicle longitudinal direction by a transverse element of the body connected to the roof rails. A roof apparatus has a frame and at least one roof element that overlaps with at least part of the roof opening. The roof element is retained on the frame directly and on the body by way of the frame. The frame has a transverse frame part, on which the roof element is retained directly, the transverse frame part being connected directly to the transverse element of the body.
