A little help guys... dealership sales question

It was a trade in but I doubt they gave the guy 16,000 for a trade in, Like I said the thing wasnt in a 2009 condition… The top of the bed was scratched to hell (spray on would cover scratches so I said ok thats not bad)… the top of the tail gate looked like they used a chain saw to cut trees and didnt care if it hit the top of tailgate. there was rust between the weather sealing rubber around the doors… the carpet was pretty beat, the seat looked like the dude slid out of the truck.
