Abstract Factory is a creational design pattern, which solves the problem of creating entire product families without specifying their concrete classes. Because you abstract a simple use case into a complex and easy to handle software design principle (in our case: a pattern), it reduces the maintenance effort and makes it more reusable. public class carSaleProduct:AbstractVehicleSaleProduct    {          string carModel;          Features myfutures = new Features();           public carSaleProduct(string ModelName)          {            carModel = ModelName;                      myfutures= VehicleFeatures(); VehicleSpecification();        }        public override Features VehicleFeatures()        {//need to replace by querying using the model name            List color = new List() { "Red", "Gold", "Silver", "white" };            IEnumerable colors = color.AsEnumerable();            Features f = new Features() { DoorNumbers = 4, Color = color, Seats = 5 };            return f;        }            public override Specification VehicleSpecification() {            Specification f = new Specification(carModel) { IsAutomaticAvailable = true, IsDieselAvailable = false, EndPrice=90000, StartingPrice=3000 };            return f;        }    }, FourbyFourSaleProduct: defines a 4x4 sales object to be created by the corresponding concrete factory and implements the "AbstractVehicleRent" interface.

Another way is to dynamically inject the service depending on the selected mode. While factory method abstracts the way objects are created, abstract factory abstracts how the factories are created.
