Whenever a dealer puts that much pressure to sell anything, it’s because they get a fat profit from it and the salesman or finance manager gets a percentage.
They know he wants the car and they already have him. Now they turn the screws, pull out the doomsday playbook to tell you about everything that can go wrong, and they get you to shell out more money. Same exact thing happened to my wife when we bought a Honda.
The finance manager was trying to sell us on an extended warranty package by basically just saying Honda’s warranty doesn’t cover anything so you need an extended warranty… she was trashing her employer in front of the customer to make more money.
