I would say that is because, well, Model X (or Model S) interior doesn't look luxurious enough given its high price. I would say you friends are basically just stating a fact. It is obvious and evident to most objective observers, IMO. Just recently, as an example, we have had a lot of talk about the poor leather quality in Tesla's seating: Perforated seats durability? I have listed some of the shortcomings in my previous posts (e.g. Model X 5 Seat Deliveries). Basically when I came from an Audi A8 to Model S in 2014, it was obvious I was giving up a lot of interior quality and settling for much less. But it was OK, because the car platform was still new, it seemed like a competent first attempt etc. And of course that drivetrain and 17" UI were the bomb. Unfortunately fast-forward to 2017, things are not much better than they were in 2014 in that regard. Few interior features and options have been added (steering wheel heating, slightly improved seating and storage) and then others have come and gone (seat ventilation, interior trim choices, seat folding on X a mixed bag), but basically three years later Teslas are still very basic cars interior-wise - more akin perhaps to a Volkswagen or Toyota, than BMW or Audi, let alone Porsche. Tesla does two things well: EV drivetrain (except Pack Performance and Launch Mode Limits) and an innovative, upgradeable software platform - and Model X has the unique, weirdmobile doors. These are the differentiator. The rest they have is mediocre at best. The interior choices especially are dramatically lacking compared to what you can select for your average German high-end model. The small number of choices are very Toyota-like and the quality is Volkswageny and not always even there. Interior features are often less than these have. Volvo does Scandinavian interiors. As some clever mind put on Electrek recently, there is nothing wrong with Scandinavian design ethos, the problem is with Tesla the quality is not there, nor are the features. Everything back from the dash (which is OK, aside from lack of trim choices) is very mediocre on a Tesla. Worse still, things have not been improving much in recent years, with interior changes more a mixed bag than some kind of clear, great progress story. Apple is an example of premium simplicity. With Tesla the premium is not nearly always there, let alone any kind of luxury. The haphazard five-seater implementation in Model X, I guess, being the latest glaring example of this at Tesla. I would not be surprised if @rainforest has a five-seater, because that adds to the lack of premium feel on the Model X. I am definitely driving a Tesla despite of its interior, not because of it. That complete interior overhaul for Tesla can not come quickly enough.
