Guys, I was in car sales for years and would never do this. Are there dip shits in car sales...yep, but far and few between. People do make mistakes, especially when you work 60-70 hours a week. Most of the "typical" car salesman are honest family guys who love people. You have to love your job and people to tolerate stereotyping that's apparent in this post.
Been around the car business my whole life, and I can tell you that most of the dealerships I've been around don't tolerate the stereotypes that are personified in this story. The ones that do this crap are ones that are in "autoplex" kinds of places like New Orleans East and Slidell, and even at those the BS tactics aren't used by salesman that have been in the game for years. Most successful, career salesman are reliant on repeat business and the most successful ones (a family member of mine included) after a few decades of doing it will get customers willing to follow them to new dealerships and brands, and they will make most of their living from selling to people they've made friends with over the years at a low commission, and the friends won't waste their time since they know the salesman isn't making much on the deal.
A good tip is when you see a dealership advertise that a salesman has moved to their dealership (usually in the classified or automotive section on the lower half of the page a page or two in), that is usually someone who has a following with customers at a past dealership. These are the guys and gals to seek out for a purchase since they understand that if they don't screw with you they'll get another deal in 3-6 years.
