This has to be a prank on someone... a M1A2 WW2 tank for 1500 if you haul it away

Found on  via have a tank out back behind my barn. I don't know anything about it really other than I haven't been able to get inside it and its been sitting for over twenty five years. It came with the property. I'm trying to do a little cleaning up around the place and its too heavy for me to move. I don't think it runs. You will need a flat bed.
