Flood history and water damage
This is the check we take most seriously here. We lift carpets and inspect the underlay, look under and behind the seats, pull the spare wheel well, extend the seatbelts fully to look for a tide line, inspect under-dash and door-loom connectors for green corrosion, check seat-rail bolts, look for silt in the boot channels and heater box, and note unusually new carpet in an otherwise tired car.
