Can you say scam? Ok the car dealer tells you he's giving you such a great price for your trade. You better watch out when this happens. Most likely he has a whole lot more profit in the car your buying that he could have given up or the car dealership would not give you this kind of deal. Understand the difference between ACV 'Actual Cash Value' and Trade Allowance. So, the next time your neighbor comes home bragging about what how much they received for their trade. Just look at them and think, SUCKER.
