Like the Maserati, it's a high-end version of something that's also available in midrange and low-end versions. The low-end does the job perfectly well but isn't as pleasant. The midrange has a nicer ride and handles better -- not enough better that it makes any practical difference, but enough better that you can notice it if you care about such things. If you're going to push the limits, or if you're exceptionally sensitive, or if you just like the snob appeal, the high end does take it that much further.
It's worth what it's worth to the people who buy it, by definition. If it isn't worth that much to you, it isn't the one you want to buy. I don't want a Maserati either, certainly not at full price and probably not even if I got it at lower price; what it's designed and tuned for simply isn't what I need.
