We deal with city, state, county appliances all the time and I can pretty much rest assured that these are going to be pretty much scrap. These are usually from care homes, group homes, prisons and jails and are ridden hard and put away wet. When they are just too beaten up or worn out, they are surplused. If you're seeing newer models, it's because they are not worth repairs otherwise they'd be getting rid of older ones and keeping these. The cabinets may look halfway decent but what you're not seeing, the insides, will tell the story. Besides, just think how good those closed up refrigerators smell, baking in the sun...
