✓The 'Wet Belt' (timing belt in oil) is the #1 risk; demand proof of oil changes using ONLY the correct Ford-spec oil.

✓Look for evidence of security upgrades; these are high-theft vehicles and the driver's door lock is easily bypassed.
✓Verify the AdBlue system is working correctly, as sensor failures are frequent.
