2. Make the lowest offer you can without being told to leave.

If you’re a good negotiator, a car dealership is a great place to test your skills in making a lowball offer, even if it’s offensive.

“You want the salesman annoyed or offended by the offer, but still willing to negotiate,” says Alex Gierczyk, a part owner of a dealership in Houston, Texas, in the early 2000s until he sold to his partner.

“This was the most effective tactic bar none,” Gierczyk says. “It leverages the fact that we want to sell the car, even at a small margin because there’s no disadvantage to increased inventory turnover.”
