Fortunately these things are all down to personal choices. I just would not personally get €180.000 of satisfaction out of my spend. My old Panamera 4S is probably worth less than €50k these days but I use it to carry trash down the dump and fill it with skis, snowboards, wakeboards, dogs, kids, paragliders and stuff - it gets abused and scratched and we just don't care. I would be worried about a €180k car getting damaged.
It's probably a very nice car, but I think may only be worth €100.000 after 2 years so dropping €3.000 a month in cold hard cash doesn't appeal to me.
The nice thing is that we can see having a reservation on the Model X has proven to be pointless in North America, and once production ramps up over this year even more worthless to a European. So when the first ones start appearing in Europe in 2017 it means that 80% of the backorders have been filled, and that they are producing up to 1,000 units a week - so at that stage it will be easy to order one and get delivery 3 months later. Even now in North America if you order the correct spec you can get a car 3 months later.
So in 2017 I can look again, see if anything is actually available as competition, maybe even test drive a car, and make a choice again.
