I seem to recall this happening in real life, a woman found out her husband was having an affair and kicked him out, leaving I think, a newish Mercedes behind,. After a few weeks she asked her ex what he was going to do with the car and he said to "sell it for what she could get". So she advertised it in the local paper for £100, when a punter arrived she insisted on him paying the £100 without seeing the car first, which he did and he got the bargain of a lifetime.
