What is the "worth it" you are referring to when you ask "Is leasing WORTH IT?"?
When you ask if one thing is worth doing in order to gain/lose something else, you need to specify what you will be gaining/losing.
I could give you 500 different answers from an economic perspective, but I could also give you 500 answers from a "chicks like dudes that drive a new shiny car every six months" perspective.
If what you meant to ask was, "What are the advantages and disadvantages of leasing?" then I suggest you copy & paste that quote into Google and see where that takes you.
Like the earlier answerers said, it depends on what matters to you.
