1993 Buick roadmaster estate wagon edition 5.7 L

I have a 1993 Buick road master estate edition. Used. Cranks and starts. Leaking antifreeze. A friend believes it to be on the backside. Either from the block or freeze plug. Interior / exterior have flaws/ defects. Paint peeling and some little dents. All windows are in good shape. Windshield has crack in passenger side. Battery is dead. Seats are in rather good shape. I'm going to clean carpets. Email with questions or concerns... local pick up only
