Looks to be a complete and solid high desert car. God awful color but well worth $500 as a parts car if nothing else. If it is as solid as it looks, it is a good potential project for a driver or restoration. Will need lots of work after sitting for 20 years and the interior is sure to be well baked. Ad sounds like somebody who just wants the car gone and the car appears to out in the middle of nowhere in eastern Washington.
