A vehicle trunk cover assembly includes two coupled guide rod units which are connectable to the cover and the vehicle body such that the cover is movable between a closed position covering the trunk, a roof transport position in which the front cover end is lifted relative to the trunk, and a loading position in which the rear cover end is lifted relative to the trunk. A locking lever connectable to the vehicle body includes a lock which is movable from an engaged position to a disengaged position upon being actuated. One guide rod unit cooperates with the lock such that the guide rod unit engages the lock when the lock is in its engaged position so that the cover may move into its loading position and disengages from the lock when the lock is in its disengaged position so that the cover may move into its roof transport position.
