I wouldn't worry about a scam. Assuming the shutter is rated to 400,000, there's plenty of life left in the body. What you may find though is the pro D4 body is large and heavy and the 16MP images may look 'great' but are rather limited in their cropping opportunities. Compared to what you can do with the D850, you may come to realize $1500 was actually way too much for the limited capabilities of an older digital camera.
Don't worry so much about the "measly" 16mp. The flagship D5 and now D6 only have 20.8mp.
The photographer who did the portrait of my daughter for for her wedding shot a D4 and the portraits came out very nicely. He also shot rodeo photos in the west with D4's and they were very sharp. It could be that the larger pixels of this series provides not only great low-light photography but sharpness as well.
