car salesmen = professional grifters, scammers, liars, truth stretchers
My favorite lie, "You'd better snatch up this car while you can because there are two people in the other room who have just made an offer." Two days later, the car is still sitting in the lot.
Another favorite, acting surprised when I show him the Kelley Blue Book value on my iphone (there's an app for that), then lying about the car model and options to try to justify himself. The KBB value was nearly half what they originally offered. Then he lied and said, "Well that's how much we paid at auction." Well then, you need to hire someone new to buy cars at auction for you, because you got ripped off.
So, watch out for these grifters. They pull out every trick in the book.
