Flood damage can severely impact a used car’s reliability. When inspecting a 2nd hand car in Japan, check for these warning signs. Musty odors, especially after cleaning, are a red flag. Examine carpets and upholstery for stains, watermarks, or discoloration. Inspect the spare tire compartment and under the hood for rust or mud. Check the electrical system; malfunctioning lights or wipers could indicate water damage. Look for mismatched interior colors, which might suggest replaced parts. Finally, a Carfax report can reveal if the vehicle has a history of flood damage. A thorough inspection is crucial to avoid purchasing a flood-damaged vehicle.
