CarDealership Class The CarDealership class will simulate a real life automotive dealership. This class will create 3 Car objects and store them in an array named Lot. The class will then display all of the information pertaining to each car (color, make, model, etc.) to the User and allow the User to select one to purchase. Once the User selects a car to purchase, the Car object should be removed from the array (Lot) and another Car object should be put in its place.
