These are late-model cars, so get full dealer service records, a PPI focused on the valvetrain/PCV/cooling, and confirm the recall. Scrutinize minor repairs honestly disclosed by sellers (repainted bumpers, PDR dents, pothole-bent wheels that just need straightening), and verify equipment (CarPlay is standard via MMI Navigation Plus).
