Maybe the owner figured out your game and explained it to the salesman, who then proceeded to use it on you.

Obviously the salesman had made a mistake. He must have had a floor price, and accidentally went below it in the heat of that powerful negotiation tactic. And it was impossible to resume negotiation after that, as he had lost all credibility because he was negotiating price levels that he didn't have the authority to decide. What was he supposed to do? Say "forget about the $16k we just agreed on, how about $17k?"

If that's the case it didn't work - the goal of a negotiation is to come to an agreement. It's trivial to disagree.

Maybe the salesman let his ego get in the way ?
