Ferrari is not recalling the LaFerrari. No sir. They are merely upgrading the fuel tanks so that the cars have less of a risk of catching on fire. That's a pretty swell upgrade.
Every single LaFerrari on the road (I have four on my block alone, it's getting ridiculous), will be called in to get this upgrade. The new fuel tank, as far as we can tell, is no better than the old fuel tank.
Well, except for the part where it isn't prone to spontaneous combustion. If that is a standard feature that you expressly purchased the LaFerrari for, then you are not obligated to take the car in for the free service.
Up to you!
