Generally, 4S stores do not sell flood-damaged cars. 4S stores are relatively formal and usually do not sell vehicles with potential hazards. However, this is not absolute, as some 4S stores may internally sell flood-damaged cars. To some extent, flood-damaged cars can be repaired, but they pose significant safety risks and may have numerous hidden faults. A flood-damaged car refers to a vehicle that has been submerged in water, typically involving the engine and transmission being soaked, with the water level exceeding the wheels and seats, and the bottom parts of the vehicle being in prolonged contact with water. Such vehicles have a high risk factor, as their electrical systems are prone to short circuits, fires, and other issues.

I don’t think 4S stores would actively sell flood-damaged cars, as they collaborate with manufacturers and brand image is crucial. Flood-damaged cars, after being soaked in floods or heavy rain, can hide numerous issues: electrical circuits are prone to short circuits and fires, body corrosion accelerates, and they might break down at any moment while driving. Last year, when I helped a friend buy a car, we found a musty smell under the carpet during an inspection of a used car at a 4S store, and the salesperson finally admitted it had been slightly flood-damaged and repaired. Since then, I’ve advised everyone to personally inspect a car before buying—pull up the seats or check the trunk for water stains; also, check the car’s history report, as the VIN can reveal if it has ever had flood insurance claims. Reputable stores have ethical policies, but you still need to be vigilant, as flood-damaged cars come with significant hidden risks.

As someone knowledgeable about cars, I understand the operational standards of 4S dealerships: they are manufacturer-authorized outlets with strict management of new cars and certified used vehicles, essentially eliminating the risk of flood-damaged cars. Restoring flood-damaged cars is a hassle—electronic modules and chassis rust and deteriorate as soon as they get wet, making it not worth the dealership's effort to sell them. In reality, occasional oversights might occur: for example, failing to thoroughly check the background of a trade-in before refurbishing and listing it. I recommend paying attention to details when purchasing a car, such as checking for a musty smell inside the car and testing the air conditioning and lighting systems. Flood-damaged cars are usually documented, so checking the vehicle's insurance history via an app can help avoid them. While 4S dealerships are relatively safe channels, it’s unwise to fully trust the dealer—verifying things yourself is the most reliable approach.

From my daily driving experience, the probability of 4S dealerships selling flood-damaged cars is low because they rely on their reputation. Flood-damaged vehicles are no small matter—after being submerged, engine and electrical failures frequently occur, and even airbags may malfunction. Before purchasing a car, I always make it a habit to check for rust under the carpet seams or beneath the brake fluid reservoir; a musty smell is also a warning sign. I recommend going to reputable dealerships, as they have standardized inspection processes. Always verify the vehicle's origin and avoid impulsive purchases. Flood damage can be easily overlooked, but a simple self-inspection can save you from trouble.

From a safety perspective, 4S stores typically avoid water-damaged vehicles, but policy loopholes may allow some repaired cars to enter the market. Driving a flood-damaged car is extremely dangerous: damp wiring can easily ignite, rusted chassis affects handling, and the consequences are unthinkable. I once experienced this: while inspecting a car, I found sludge in the spare tire well, and the salesperson was evasive. Reputable dealers have a responsibility to ensure transparent transactions. It's advisable to request maintenance reports or use an OBD tool to read fault codes. Consumer protection laws safeguard buyers—if you encounter anything suspicious, file a complaint immediately. Prevention is far better than dealing with repairs after the fact.
