That's true of any German car. If you bought cars with your brain and a ledger, you'd always end up with Korean nowadays (Japanese only a few years ago) in the states, probably Malaysian in the EU.
I think the CLA is an overall dumb purchase if you are thinking logically, but to live life completely governed by logic is rather boring. Besides, there's nothing wrong with the occasional irrational purchase (as long as you can afford it). Many companies live by them. Look at Apple, Beats, Coca Cola, etc, etc. And, of course, Mercedes-Benz.
