Acquisition of a car that has been drowned, according to the degree of risk, can only be equated to the acquisition of a car assembled from the components of broken cars. If the car is “drowned” and does not fall apart in a few weeks or months, then the time, nerves and money spent on repairing it during operation will be truly enormous.
The only advantage of such a purchase can be called only the low cost of the mermaid car. You should know that in the absence of obvious signs of wetting the car for it will be unknowingly to pay the full cost.
But the disadvantages of such an acquisition will manifest itself "in all its glory." If the car does not lose its attractiveness at the time of purchase, its susceptibility to corrosion over time will manifest itself by rotting the body, which will be especially intense if the vehicle is in salt water. This will result in the need for periodic regular replacement of failed mechanisms.
Inevitable will be the rapid failure of automotive electronics exposed to moisture, because to dry it, as a car as a whole is absolutely impossible.
The engine flooded with water is another “risk zone”. Although the motor may still function for some time, at any moment it may stall, will act intermittently, and may even ignite. A water-oil emulsion will accumulate in the car's engine, and this circumstance will one day make the car completely unusable, and the cost of repairing this problem will inevitably be equal to the amount that will be saved on buying a new car, or even exceed it.See also: Rent a car in the USA
Harmful wetting factors and risk
Theoretically, a car that has been in the water cannot be considered a reliable means of transportation, but precedents are rather long, in some cases many years, the operation of such vehicles is taking place. The level of reliability of “drowned” cars is extremely low, but such a deficiency can also occur in cars that have a clean history, and some car owners manage to drive a few years on such a drowned man without even knowing about his wet past.
It is curious that a certain role here is played by the property of water in which the machine has visited. Failure of the electric filling of the car and the mechanical part of its design really occurs under the action of moisture, but the consequences of such an impact will be especially serious if this moisture is salty. If the car was sinking in fresh water, and immediately after it was thoroughly dried, the consequences may not be so sad. If the car was in the water of the sea, then over time the destruction will become really fatal.
The purity of the water also plays a significant role. If the car fell into the clear water of a mountain river, then it is not so bad, but when it becomes a reservoir with a high content of sludge, clay and other debris, cleaning the inside of the car away from them becomes a very serious problem, and the ingress of these impurities into its mechanisms and electronics - a disaster.See also: Tire pressure monitoring sensors
The factor of time spent by the machine in water is also important. If the water was still unsalted and clean, and the car spent a few minutes in it and was quickly removed from the water, the level of damage would be minimal. The main thing in this situation is timely, thorough and quick drying and cleaning of the car, replacement of filters and oil. But if a simple machine in a flooded state took several days, then no “resuscitation” measures will save. This machine is suitable only for scrap metal.
Therefore, purchasing a recessed car in order to save money on this is suitable only for those who are not afraid of difficulties, however, purchasing an outdated car can be a much more acceptable option for such savings, from which you can hardly expect so many surprises as from a “recessed” car.
