    public Producent Producent { get; set; }
    public int Age { get; set; }
    public int YearCreated { get; set; } 
    public Engine Engine { get; set; }

Answer 1

Here you can find details Using Properties

It will be something like

 public class Car
    {
        public int Age { get; set; }
        public int YearCreated => DateTime.Now.Year - Age;
    }

Answer 2

You could turn YearCreated into an expression-bodied property . See below for example.

Note that this makes the property read-only. If you need to be able to override the property, you will need to add a backing field and give the property a body.

public class Car
{
    public string Id { get; set; }
    public Producent Producent { get; set; }
    public int Age { get; set; }
    public int YearCreated => 2023 - Age;
    public Engine Engine { get; set; }
}
