The bottom line
When you're standing in front of a used Prius, treat a live scan and a look underneath as non-negotiable. Active error codes hit nearly two in five of these cars and oil leaks sit right behind them, so a dirty scan plus a wet engine is your cue to walk or cut the price hard. Next, check tire wear and the pressure-monitoring system; those faults stack with dead lights as the usual tell that basic upkeep was skipped. A respray is normal here and not a deal-breaker on its own. Pay asking only if the electronics are quiet, the engine is dry, and the rubber is honest.
