As a former car salesperson I find this thread amusing. I can tell you that I knew the data on every new vehicle I sold because I was the nerd sitting with product manuals fresh off the press. Used vehicles were a little tougher to know all the stats. 50% of my sales were to Ford A-Plan customers, which made things pretty cut and dry. Fixed price, below invoice. I also sold a lot to Delta employees which had a special deal with our dealership at 1% over invoice. And then the internet happened. People would come in with their Kelly Blue Book or Edmunds price telling me what we had into a car, how much invoice was, what the holdback was, and how they wanted the vehicle for that price or they would walk. So I told them, Have a nice day and come back if they were willing to pay me for my work. Never understood why so many people think that because they know the price to the store figured that they were owed the same price. In what other industry or business does that work? Does one go to Walmart to haggle over the price of a TV? To Waffle house to haggle over the price of hashbrowns? But with cars, everyone wants to get the lowest price possible. Well that's fine. Get it off the internet, and stop going to dealerships to deal with humans.
I can tell you after having sold well over 1000 cars, that never once did I rip someone off. Not once. Why? Because I was selling a product and they were buying a product, and in the end we both agreed to sell and buy the product. I never held a gun to anyone's head, although I did kick a few people out of the dealership. I called it firing customers. I only got paid when I made a sale, so if someone was abusive (I'm a pretty tough guy, but I'm not putting up with some butthole that treats me with disrespect, and sees me as their servant), I'd tell them that they were not the type of customer I wanted, and that they should leave. You should have seen their faces, as I turned the tables. Priceless. Suddenly the big talker was told to go walk.
RE: Talking to women about cupholders- that was maybe a new or poor salesperson. A good salesperson knows how to read a customer. I was usually quiet, and the encyclopedia of knowledge IF the customer asked a question. But to stand there spouting off stats is sort of ridiculous in my opinion. Have the knowledge available, but geesh, what are you that Dr guy from Criminal Minds?
Anyway- I've always said that a good deal is a state of mind. I've sold cars to people at below invoice and they were nothing but complaints and trouble, and I've had clients who paid sticker price that sent me every single relative and friend they had. It's often the service after the sale where one truly gets what they pay for. There are some creeps in the business. I know because I worked with some of them, and outsold them most months. There are creeps in every business. There are good plumbers and bad plumbers too.
