He's right, they have low payments, that drag on and keep going with interest. 90% of the time you will have to fix the car in a major way long before you even get it paid off. Its almost criminal but it IS still legal because people do what they have to, to be able to get around. Around here they thrive because we have little to no public transportation, so its either walk or pay to play.
I had a friend that got a job cleaning them up for one business. He said straight from the auction they were among the nastiest cars he had ever seen/smelt. He worked for 2 days and quit because of one that had bugs thriving in it off the old junk food, just *shutters*
