Using C#:

Create a project for a car dealership. The project, named
CarDealershipCalculation, allows a user to use a ListBox to choose
a type of vehicle from at least four choices (for example, Honda
Civic). When the user selects a vehicle type, the program should
display a second ListBox that contains at least four types of trim
levels (for example, Touring). After the user selects a trim level,
the program should display a third ListBox with at least four
choices for additions (for example, Custom Rims). Display a message
on a Label that lists all the chosen options, and make the trim and
additions ListBoxes invisible. If the user makes a new
selection from the first ListBox with the main vehicle choices, the
trim option becomes available again, and if a new trim selection is
chosen, the additions option becomes available again.
