A motor vehicle has a folding roof which can be opened and lowered into a rear storage space. Partitioning of the rear storage space into a folding-top space and a residual luggage space is provided by a separating arrangement which includes a dimensionally stable covering element that can be shifted vertically from a use position into a non-use position when the folding top is stored. The covering element extends over a rear sub-length of the separating arrangement and can be displaced forwards into the non-use position shortening the length of the separating arrangement.
