Menu Error displaying info on a List

Im having problems with a menu I made for a small app I am doing for a school project.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace Teste_Menu
{
    class Program
    {
        static void Main(string[] args)
        {
            List<Modelo> ListaModelo = new List<Modelo>();
            ListaModelo.Add(new Modelo("Honda", "Civic", 180, 29000));
            ListaModelo.Add(new Modelo("Honda", "Jazz", 100, 15000));
            ListaModelo.Add(new Modelo("Honda", "HRV", 115, 22500));
        }

        static void Menu()
        {
            string escolha;

            do
            {
                Console.Clear();
                Console.ForegroundColor = ConsoleColor.Magenta;

                Console.WriteLine("\n");
                Console.WriteLine(" ==================================================================================================== ");
                Console.WriteLine(" =========================================== Cars ================================================= ");
                Console.WriteLine(" ==================================================================================================== \n\n");
                Console.ForegroundColor = ConsoleColor.White;
                Console.WriteLine(" Consultar Lista de Carros -----------------------------------------------> (1)\n  ");


                escolha = Console.ReadLine();

                switch (escolha)
                {
                    case "1": ListaModelo();
                        break;
                }
                Console.ReadLine();

            }
            while (escolha != "2");
        }

        static void ListaModelo()
        {
             {
                 var ListaModelo = new List<int>(Enumerable.Range(0, 50));

                 ListaModelo.ForEach(Console.WriteLine);
             }
        }

    }
}

When I execute it shows no Erros but doesn't give any output.What am I doing wrong here? It just shows - "Press any key to continue"

static void Main(string[] args){
    List<Modelo> ListaModelo = new List<Modelo>();
    ListaModelo.Add(new Modelo("Honda", "Civic", 180, 29000));
    ListaModelo.Add(new Modelo("Honda", "Jazz", 100, 15000));
    ListaModelo.Add(new Modelo("Honda", "HRV", 115, 22500));
    Menu();
}

you didn't call the menu function that's why it didn't gives any output. If still no output, try to pass your list.

Your Main method simply creates a list and adds items to it; the rest of your code never runs. The end of Main hits and the program exits (as all C# programs do when the end of Main is reached) You need to actually invoke the Menu method:

static void Main(string[] args)
{
   ...
   Menu();
}

You might also consider passing in the list of cars, because its not going to be available to any other methods where you have it right now either.
