I think I just lost a few thousand brain cells reading this crap. Homeboy makes no sense whatsoever. On one hand he's telling us he doesn't mind scratches or dings on his car. The next thing I know, he's selling his car because (in his mind) the car will never be the same after the body shop fixes it! I've heard of freakish OCD perfectionism but there's no consistency here!!
Clearly there's something else going on... something else none of us will probably ever know about. The first clue is when he mentioned he hasn't been indicted!! Can you say freudian slip? If we were to put our subject on the couch and psychoanalyze him, we might find out that he did something terrible (perform a hit for the mob maybe?) and has thus created a negative association with the car. Because he's so ashamed of what he did, he has to get rid of the car in order to avoid further torment. This dent serves as a reason (albeit a ridiculous one) to sell the car.
P.S. Relax... I'm only kidding around! (or am I???) Seriously though... your rationale is pretty absurd. If you're not working for the mob, you should think twice. Losing "a few thousand" on a new car is not cool.
