At first glance, looked like this was another example of some junkyard deciding to post some car that's been in their yard for years. But looking through the pictures I see the car is just really dirty on the outside. Looks like it would clean up pretty good. They don't list a price but I bet you could pick this up for a song.
It's also sitting on a dirt floor. It'll depend on just how deep it's sunk into the dirt and if there was any moisture and condensation present. Otherwise, if you like plain-jane low mile LeSabres, this is the project for you. The nice thing is it would be simple, there are no options besides A/C to speak of on that car.
