Why most people prefer to buy used cars

When you talk about people and how some of them prefer to buy new cars and how most of them think buying used cars is better then you need to understand that different people have different situations they are in and according to those situations they make their decisions and have their preferences. When I was going through the list of car dealers in Tokyo to find a good used car for myself I simply thought of buying a used car because it was falling in my budget. Most people usually buy used cars because of their budgets, do you agree?
