        }        
    }

    public class Car
    {
        public int id { get; set; }
        public string make { get; set; }
        public string color { get; set; }

    }
}

Wie kann ich die Liste aktualisieren, indem ich das Honda-Auto mit der ID 1 durch das Honda-Auto mit der ID 3 ersetze?
