Considering this to be conventional wisdom, car owners need to take care of their cars. Moreover, they need to take are of their vehicles the way they would take care of themselves. The last thing car owners want to experience is a breakdown with their "Mr. or Mrs." Suppose you want to sell your car in a few years. Without proper maintenance, no one would want to buy it. For example, who would want to buy a car full of rust and dirt?
Moreover, car owners need to wash their car regularly. Failure to so would lead to subsequent mishandling. Also, failure to clean your car will result in extremely expensive car repairs. Furthermore, you will end up paying thousands more to fix your car than the repairs actually cost. Also, the dirt particles will lead up to depreciation. Therefore, make sure you wash your car on a weekly basis.
