//TestCars1 produces the following output.Notice especially the results for car2, which probably are not what you expected.
//The type of the object is ConvertibleCar, but DescribeCar does not access the version of ShowDetails that is defined in the ConvertibleCar class because that method is declared with the new modifier,
//not the override modifier.As a result, a ConvertibleCar object displays the same description as a Car object. Contrast the results for car3, which is a Minivan object.
//In this case, the ShowDetails method that is declared in the Minivan class overrides the ShowDetails method that is declared in the Car class,
//and the description that is displayed describes a minivan.
