Repo-man

The Repo-Man is an NPC that visits a Sims's Residential lot when they neglect to pay their bills. Over time, after bills have been delivered to a house, they change color, going from white, to yellow, to red. As they progress through the colors the need to pay them becomes more urgent. If bills which have turned red are left unpaid for too long, they will explode and summon the Repo-Man.

He usually takes one or two items but if the Sim is in a large amount of debt he may take several. The items he takes (approximately) add up to the the amount the Sim owes. The Sims of the household get a negative memory for each of the items taken, and may periodically cry about the lost item.
