I would have ran away too. Everything you mentioned just screams "poorly maintained." Cheap isn't always the best way to go.Took a look and test drive. Guy started at $6k. Ad said $5k. Paint faded bad. Was a NM car it's entire life. Gravel road paint chips bad. Windshield had 3-4 stone chips. Tires weather checked. Smokers car. Blower motor only worked on high. AC did work though. Brake rotors pitted from sitting. Battery looked corroded and old. As we talked he mentioned scammers and people who wanted him to hold it who never came up with money. Told him I had cash in hand but wasn't sure it is what we are looking for. He talked himself down to $4k before we left. Honestly a fair price for a kid driving locally. Drive it a few years and get your investment back. My gut said to walk away. Never made an offer. Dude wants it gone NOW so he can go buy a pontoon. Lol
