Imagine you and your neighbour.
He just ordered himself a shiny new Merc for his wife and is looking to sell her two year old Cadillac.
Your wife wants a new car as well but you can't afford that shiny new Merc at the moment. You can however, afford their second hand Caddy. The problem is whether your wife would be willing to be seen driving around in her neighbours old car.
It's as simple as that
