You're not.
I'm not really enamored with super fast cars either. I respect them for what they are capable of, but the staggeringly vast majority, will never use anything of their potential. They will just be rich peoples trophies, something shown to prove their wealth to others, which I personally find, kind of sad.
Even if I was ridiculously wealthy, I'd rather build a fast car, than buy some supercar (XJ220 excepted, cause dead sexy). Besides, more fun to drive a slow car fast, than it is to drive a fast car slow :D
