It's just like insurance. How often does my house got flooded, on fire, blown away by tornado, collapsed because of earthquake?
My home hasn't experienced any mishaps but why do I still pay insurance for something that has never happened to me in the past?
Same with my good health: I haven't experienced any illness yet but why do I still pay for health insurance premium every month on my pay check?
So, if you ask me about your Model X, I would say: get it!
