Adversary

Ask how someone actively working against you would beat this. Not a neutral other party with different interests, but a hostile one hunting for the weakest joint. What they would attack first tells you where your plan is actually thin.

Example

On the car sale: a professional flipper sees no service records, a seller who mentioned moving in three weeks, and a listing up for 20 days. He would stall, then re-offer $800 lower on day 19. That tells you to post the records now and stop naming your deadline.
