I think in your post you also have your answer, but here is what i think. The Huracan is definately the most driver orientated Lambo so far and i would dare to say, the most driver orientated car in it's segment. Considering it's versatility especially equipped with magneto suspension it almost makes it as comfortable and usuable as a daily driver. Considering this this car will be driven a lot, much more in my opinion than the Gallardos or Aventadors. That being said i do not think the mileage will have such an great influence as it had on past models.
As for depreciation of course that prices will drop, another big factor will be the next announcement from Lamborghini on how many Huracans have been ordered (as you all know 3000 worldwide, 1000 in US so far).
