A common strategy for gaining compliance used by car salespeople is the door-in-the-face technique.

The door-in-the-face technique involves making an initial large request that is likely to be refused, followed by a smaller request that is more likely to be accepted. This strategy is not commonly used by car salespeople, as it can be seen as manipulative and reduce customer trust. Car salespeople often use other techniques such as foot-in-the-door, social proof, and scarcity to gain compliance.
