I sold an 83 Toyota to a 19 year old kid back in 2011. It had probably been in the woods since 1995, and was sold as a wheeler not a DD. The kid drove test drove it and agreed everything was how I said it was, paid me and left with the truck. At 4a.m. that night he starts calling and texting saying the tail lights don't work and his dad will kill him for buying a truck like that and wants his money back. I rolled over and went back to bed, he apparently delt with that issue because it never came up again. However about 3 weeks later I get a picture of the truck with a busted windshield. Then he calls and tells me the steering wheel came off and he crashed the truck, says I knew it was unsafe to drive and if I didn't pay for everything he was going to sue me. I told him to go ahead and sue, and that we would no longer need to communicate with each other since he's filing against me and that his lawyer can contact me for anything he needs. Nothing else was ever said, I didn't get sued, and he is probably still an idiot. People make bad choices and try to pass the effects of them off to someone else. Sucks for the dude that bought the 7.3, but don't sweat it. If he had a $200k job lined up he wouldn't have been looking at 7.3 in the first place.
