Interesting. Then either the Sigs are getting a discount or some options are going to be cheaper. Maybe the $3,000 range upgrade is going to get thrown in? And "Next Generation" seats won't be applicable anymore, just a flat charge for leather?
Yeah, I did a bit of tinkering too, but without knowing Production pricing, it's hard to be sure of anything. I'd really rather not have a P90D (mainly for range concerns), but if I HAVE to, the price seems decent.
As stated well above in the spread sheets, Elon stating that the base X is $5000 more than the base S is not an apple to apples comparison. For an equivalent S 70D, you would still need to add the $3000 rear seat option and $1500 panoramic glass roof to equal that of a baseline X that has (I believe) standard 3rd row and panoramic windshield. From what I can tell, the baseline X is $500 more.
The base X will not have 3rd row seats. And one can make the case that an openable sunroof (like the Panoramic roof in the S) is not directly comparable to the X windshield and skylights since they are fixed.
