Monicaaaaa, I think that I will be able to help you with this question. As I know, people have very different attitude towards this thing, so you need to learn more here by yourself and then decide whether you need it or it's just a waste of money and time. It also depends on the type of car owner you are. If you don't have a lot of cash so of course, there is no need to spend anything on it. Think about it.
