        {
            cars e1 = new cars();
            books e2 = new books();

            //cars parameters

           e1.mark = "BMW";
           e1.model = "M3";
           e1.color = "Silver";
           e1.price = 13000;

    }



}

class books {

    }
}
class cars
{
    public  string mark;
    public  string model;
    public   string color;
    public  double price;
    public cars(string markee, string modelee, string coloree,double pricee) 
    {
        mark = markee;
        model = modelee;
        color = coloree;
        price = pricee;
    }
    public  void WriteInfo()
    {
        Console.WriteLine("cars: mark: {0} model: {1}. color: {2}. price: {3}", mark, model, color, price);
    }
}

class Program
    {
        static void Main(string[] args)
        {
            cars e1 = new cars("bmq","","",0.2);
            books e2 = new books();



            e1.WriteInfo();

            //book parameters
            e2.author = "Fyodor Dostoyevsky";
            e2.genre = "morality";
            e2.name = "The Brothers Karamazov";
            e2.price = 25;
            Console.WriteLine(e1);
            Console.ReadKey();
        }
    }

use a constructor for this SO that you can built your object, learn constructors, i ve put some silly values inside but you ll figure it out, do the rest on your own

try this then:
`

 class Program
    {
        static void Main(string[] args)
        {
            cars.color = "blue";
            cars.price = 0.2;
            cars.model = "volvo";
            cars.mark = "volvo";



            cars.WriteInfo();

            //book parameters

            Console.ReadKey();
        }
    }
}
class cars
{
    public  static string mark;
    public  static string model;
    public   static string color;
    public  static double price;

    public static  void WriteInfo()
    {
        Console.WriteLine("cars: mark: {0} model: {1}. color: {2}. price: {3}", mark, model, color, price);
    }
}
