The Tesla website has more details about the standard and optional features - but no pricing.
The Motor Trend review does have pricing.
Combining the two sources, it looks like the first production cars will be only RWD/310 mile battery packs and include the Premium Upgrades Package ($5K, which appears to include all of the premium options listed on the Tesla website).
EAP/FSD appears to cost the same as S/X - $8,000 ($10,000 if activated later).
The only other two options that may be available are $1,000 to upgrade from the standard black body color and $1,500 to upgrade from 18" to 19" wheels.
The configuration Motor Trend reviewed was a top-end $59,500 configuration - which is about 1/2 the price of a fully loaded S 100D, with 335 miles of range and 2X cargo capacity.
The bare bones $35,000 is pretty stripped down - manual cloth seats, no power folding/heated mirrors, basic radio, metal roof, manual trunk, ...
After looking at the configuration, my wife's ready to place our order - her only question was whether she should wait another year for the dual motor configuration or order the fully loaded 310 RWD version - and hopefully get it by the end of the year.
