Let me guess, that HUGE crack wasn't disclosed in any way until you arrived to look at the 801Ds. I would have called him a prick/idiot and tell him to give me $20 for wasting my time and if I didn't pay up spit on his shoes. If he's not wearing shoes, apologize in advance to him and explain that if he were wearing shoes you wouldn't have to spit in his face, and proceed to do so.
