I'm not so sure that it makes sense to try and apply logic (cost / benefit) to this subject. Using stats is irrelevant as well.
It's a lot like wines and watches. You're tipping your hat to the engineers, the visionary guys who came up with the ideas and didn't compromise quality for scale. The people who still craft mechanical art by hand.
You buy an exotic because you can. If you came into your ability to afford such a thing by putting the same passion and precision into whatever it is that you do then you pay it forward by paying too much money for something you don't really need and you do it with a smile.
And all your friends and enemies should do the same (if they can) and acknowledge it as such.
