One GNX was traded in during Cash for Clunkers, if I remember correctly.
that would have been a crazy move on the individual and the dealership to run it under cash for clunkers.. but the dealership could have just done a regualar trade in and give them the 3500-4500 the customer was expecting, and the dealership could turn around and sold it for major profit.
Not to go off topic, but I THINK there was strict rules that threatened severe penalties for any dealership that didn't follow through with the insane C4C---not that it didn't happen and it was probably near impossible to catch a dealer doing it.
Good god C4C was one of the dumbest acts in modern times.
