Answer 1

Sun1 ,
I think it'd be better if you use property with setter and getter in the Car class instead of this.[item] = [item] and return it, like this:
public string Model {get; set;}
/*get; set; is the shortcut of:
private string model;
`get {return model;}
set {model = value;}`
*/
[...]
Here's an example of property using the code you provided:
