Buying Tips for the 2022 Ford Fiesta Mk8 (B479)

✓Early 1.0 EcoBoost cars need hard evidence of correct-oil servicing and, ideally, earlier-than-book wet-belt work rather than vague promises.
✓Watch coolant level and staining around the bottle and thermostat housing because small leaks can become big engine bills on these three-cylinder cars.
✓Test Sync, Bluetooth, door latches and both keys properly, because software glitches and locking faults are common enough to use as bargaining points.
