Ok ok ok.. So how would everyone have liked to see this end?
Here's my speculation on how it ended.
They got back to the dealership in one piece. She asked to speak with the manager and reported him for verbally abusing her. Then said she would keep looking at other dealerships, and left.
The salesman, for his part, went home and uploaded the video of their secretly videotaped argument to Youtube like a spineless bitch while mashing F5 to wait for the "I feel you bro" comments to start flooding in.
