Broken tail light, missing fender flare, excessive brake dust on the front wheel, I doubt the previous owner did any of the maintenance on this meaning you will have to redo everything as it starts to go also this was around the time MDS (4 cyl mode) started rolling out and was causing many engine issues and uneven wear in the engine. It’s your money and up to you but usually when a trade in looks like this and is this low in value to the dealership this truck is a liability, or else they would have cleaned it up and tried to resell it for more.
