1.Enter cars information (car brand, car model, car color, buy- price, sell-price)
2.Allow him to add cars at the end of his list.
3.Give him a chance to delete an item from the list using the car brand and color.

                                        System.out.printf("%s %s %s %d %d ",list.get(i)._brand,list.get(i)._model,list.get(i)._colour,list.get(i)._bprice,list.get(i)._sprice);
                                }
