Listings for used school buses are available from eBay, Public Surplus and National Bus. Listings on each site disclose the mileage, location and capacity along with many other attributes. Pictures are typically available.
Buses available on Public Surplus are usually sold directly from the school district. Public Surplus is an auction site where the highest bidder wins, although sellers can set a minimum price they will accept. EBay uses auctions as well, but also has a buy it now option where sellers elect to use a price that will end the auction if a buyer chooses to pay it. EBay has a vehicle purchase protection program that protects purchases up to $50,000 from fraud or undisclosed defects.
