What items don't correlate their price premium to their functionality?

It tells time, that’s the function.
A 10-dollar Casio will do that as well as any watch.
200 is just for the fancy-pants stuff like compasses and such.
Anything above that and it’s fashion, pure and simple.

So with that logic, Ferraris and other exotics are for fashion, pure and simple, compared to say, a Hyundai Accent.

MV Augustas an Ducatis are just fancy pants fashion over a Ninja 250.
