Zero.
I thought it was funny because I think Monte Carlo cars are ugly unless they're from the 70's, and this guy's is a '84. My dad told the guy that IF it happened, it would have to be the car and some cash, that without even seeing the car, the guy would have to pay $2000 along with the trade.
My dad was actually making the trade for himself and would have paid me the difference for the car (after the $2000 cash) since he knows I don't like those cars and don't want a car I can't drive year-round but he would like to have one as a nice extra nice weather vehicle.
