Had a salesman at a Kia dealer in Plano try to do a job on me. The fact that he was so blatantly trying to screw me indicates that they were used to screwing their customers.
Now, I expect to end up the loser on any car deal. But I was offended that he didn’t even try to fast talk me or scramble the numbers - he was going to let me have the car at the full sticker price with no markups (this was near the end of the model year and near the end of the month). And he handed me the written offer with a straight face.
In the 1980s I wanted to sell a 1979 Dodge sedan to John Hine Pontiac of San Diego. I was offered $1,900.00. I decided to think it over, returning the next day. They reduced their offer to $1,800.00.
