Does she have ALL the accessories that came with the machine? Genuine Pfaff feet are not inexpensive to purchase, also is the accessory attachment/box with the machine? What about the carrying case/cover and manuals? Is she the only owner of the machine? If the answer is 'No.' to any of these questions I would walk away and not give the machine another thought. If it is missing accessories and or she can't find them, what does that tell you about how she cares for her machine and other equipment? My sewing room may get to being a mess but I know where every foot is for every machine in here. Maybe I'm anal when it comes to keeping machines and their parts together.
