Flooded cars are one of the most dangerous used-car traps in Nigeria because they can look clean after detailing. A seller can wash the interior, polish the body and spray perfume, but water damage often returns later through electrical faults, mould smell, rust, gearbox issues and repeated sensor problems. This matters more during and after rainy season, especially for cars imported from flood-prone foreign markets or cars used in flood-heavy areas of Lagos. Signs I would check: 1. Damp smell or too much perfume 2. Rust on seat bolts 3. Mud under carpet or boot floor 4. Water marks inside door panels 5. Random electrical faults 6. Corrosion inside fuse boxes 7. Warning lights after driving A strong air freshener inside the car is not proof of flood damage, but it should make you look closer. Check under the carpets, inside the boot, under the spare tyre, beneath the seats, and around seat rails. Next, test every power window, central lock, seat control, dashboard light, infotainment button, reverse camera, AC control and headlamp. Flooded cars often develop random electrical problems. During the test drive, watch for gearbox delay, rough idle, warning lights and strange smells when the AC is on. A cheap flooded car is not cheap after repeated rewiring, ECU repairs and interior work. If two or three flood signs appear together, walk away.
