1. Appearance inspection: After a car soaked in water, fog lights, tail lights, car lights, etc. may have water ingress. You can make a preliminary judgment by observing whether the lights have signs of water intrusion.
2. Interior inspection: Open the car door and observe whether there is mold or moisture in the carpet, seats, ceiling and other parts of the car. If so, the car may be soaked in water.
3. Odor check: After the car has been soaked in water for a period of time, there may be an unpleasant musty or damp smell in the car, which can be judged by smelling the smell.
4. Chassis inspection: Check whether there are traces of mud, water, etc. on the chassis, especially the drainage holes, suspension systems, exhaust pipes and other parts near the chassis.
5. Mechanical component inspection: Check whether there are traces of water on the engine, gearbox and other mechanical components, especially the oil dipstick, hydraulic oil tank and other parts.
6. Driving inspection: A water-soaked vehicle may experience abnormalities during driving, such as engine jitter, insufficient power, abnormal braking, etc. These problems can be discovered through a test drive.
