Considering purchasing this Dart

Run away from that car!
As all of the others mentioned of it's flaws and description, the one thing in particular is him stating that he's moving ''off the grid'' and to me that sounds very suspicious.
He either is a druggie or is moving away to get away from his child support.
Worst yet, he might be wanted by the police or something similar.
Steer clear of someone like that...............
