The rear compartment looks damp and moldy. I guess you could spend some time cleaning, but I would look for a new dash pad.
Plus wouldn’t an Impala have carpet vs that black police mat? That looks as ill fitting as the dash pad.
But it does have the dreaded passenger side tail gate sag, that usually indicated a cracked regulator. I hope it finds a good home, but it would take a lot of work to actually restore it. That does not bode well for it.
