Pre-purchase checklist for this generation

Beyond general maintenance history, there's little engine-specific risk to flag.

If cross-shopping the EcoBoost version, that engine's water pump checklist is worth reading first.

Ask about towing history if applicable, and check transmission behaviour under load.
