The bottom line
Standing in front of one of these, do not let fresh paint decide the deal. Repaint is routine and structural repair did not appear, so the body is the calm part of the story. The engine is not: oil leaks showed up on 59% of them, cooling issues and engine electronics follow, and codes had been cleared often enough that a quiet dash is not proof of health. Start cold, looking for seepage and a low coolant level, then insist on a full scan. Stacked leaks, cooling trouble, and live codes are your walk-away or a hard negotiation; worn tires are just a line item.
