Maybe slightly off-topic, but seeing this, I looked back at what I received just over one year ago (car delivered 9/23/15), and compared the prices I paid with today's. Using the closest comparisons I could and not giving up anything, the closest equivalent to my car today would cost $94,000 before tax rebates, versus $86,250 last year (excluding destination charge). The extra $7750 is because of the higher prices for the autopilot features (5000 versus 2500), next generation seats versus the standard seats with leather (no longer available -- difference of 750), and a higher price for the basic car ($79,500 for the 75D versus $75,000 for the 70D no longer available).
Initially that struck me as a big jump. But actually the higher basic car price is mainly due to the larger battery so in a way that shouldn't really count. Also, there is now no alternative to the Next Gen seats and their price is the same as it was a year ago. There wasn't even a price change for the premium package, even though it now includes the HEPA air filtration feature. Plus the car now comes with a front center console (which I paid extra for) as well as improved headlamps. So the only "real" increase is for the more advanced autopilot features. I must admit, the price for that package does seem awfully high (it's as much as all-wheel drive and more than any other option available) and if I were ordering today I might hesitate to buy it.
But overall, I was pleasantly surprised that the pricing actually has not increased at all for the basic car over the past year despite several improvements, except for the AP.
As to the OP's initial question -- As to whether or not I would order the same features again, I might get silver paint (which was not available when I ordered) versus red and save $500 there, but I don't think I would change anything else. I have not felt as though the Premium interior is really "worth it," frankly, but now it has the HEPA filter and the dynamic headlamps, so that makes it more worthwhile. (I do like the power liftgate, though!) And I do think I'd still spring for the leather seats. As for the Subzero package, I have not been too impressed with it except for the heated steering wheel. But in my area, a car without it would be at a disadvantage so I'd probably get it again. (Does not apply in So. California, though). I have been happy with the audio and the suspension and would not change my selections there.
And as I said above, I am a bit torn about the enhanced AP. It seems very pricey, especially compared to the AP version 1 capabilities. So what i might do there is to wait and see how it works once it is implemented and decide later whether or not to activate it after delivery. Of course, that raises the eventual cost by a grand, so...tough choice!
Good luck!
