Lesson 24: Inconsistent accessibility error


I've been following along with the lessons, and learning a lot. Thank you very much!

I'm experiencing a hiccup tho. It seems we can not nest a public class inside a private collection. I tried changing the modifier to public for the ObservableCollection<Car> but that didn't work either.
using System;
using System.Collections.Generic;
using System.Collections.ObjectModel;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace BindingToCommands
    class Car
        public int ID { get; set; }
        public string Make { get; set; }
        public string Model { get; set; }
        public string CheckedinDateTime { get; set; }


    public class CarDataSource
        private static ObservableCollection<Car> _cars
            = new ObservableCollection<Car>();

        public static ObservableCollection<Car> GetCars()
            if (_cars.Count == 0)
                _cars.Add(new Car() {ID = 1, Make = "Oldsmobile", Model = "Cutlas Supreme"});
                _cars.Add(new Car() {ID = 2, Make = "BMW", Model="550li" });
                _cars.Add(new Car() {ID = 3, Make = "Honda", Model = "Accord" });

            return _cars;
