if you want to do minimal change always go for polymorphic classes..
first find the services you need ...& designa interface class that contain all methods
virtual....now we can have different cars..
so derive yr inventory class for each car from this interface


now tha benifit is this...that this design is extendible..we can add n no: of classes as child class .....may be in future we  will get some other requirement....so we can add the class for that as the child class to the interface no need to changer the interface
or client code(main())
