Abstract: A vehicle having a roof handhold arrangement includes an openable and collapsible cabriolet roof with an elastically deformable handhold connected at each end to handhold attachment points on lateral structural members of a collapsible roof. The collapsible roof is collapsible at least between the handhold attachment points, reducing the distance between them, and the handhold is foldable into a roof fold extending transverse to the longitudinal direction of the vehicle and bulging toward the outside of the roof. Upon collapse of the cabriolet roof by the opposed motion of the handhold attachment points, the handhold is deformable from a service position into a storage position in a transverse fold region of the roof.
