Ford: If you have selected this character then you may build one factory, or parts factory, in a location that you already have one or more factories in. You may do this when it is your turn to perform an action. You complete this special action in addition to your normal action, either before or afterwards.
Durant: If you select this character you must immediately build one factory in a unoccupied model space. You must still expend R&D cubes if you wish to build in a space ahead of the most advanced factory. You can use the R&D cube that you take when you select this character to do so. You must still pay to build the factory.
