That's the price I've seen per window: $400 for four sliders. (fortunately, my truck only has middle row seating, so I only needed 2!). They're rare because they're held in with friction tape, or glass channel tape, and after years of pushing the latch forward to slide the window forward, they just pushed off the edge of the glass. Then they probably got stuck in someone's house, tool box, garage shelf, whatever, and lost.
Same thing with Suburban rear seats... there must be garages all over the country using those as couches, because hardly any Suburbans have them anymore.
