Haven't read through the whole thread but I've been pricing out potential options partly out of personal interest and partly for investment purposes. I expect there to be fewer options than S/X, I expect the base model to have a 50kWh or 55kWh pack, this list assumes 55kWh though I was leaning towards 50 after reveal Part 1.
Base price, 55kWh, 225 miles range.......... $35,000
75kWh battery (~300 miles range).....+ $5,000
Dual motors........................................+ $3,000
Enhanced Autopilot............................+ $3,000
FSD.....................................................+ $2,000 (Requires Enhanced Autopilot)
Premium package................................+ $2,500
Larger rims.........................................+ $3,000
Leather seats........................................+ $1,500
Vegan seats..........................................+ $1,500
Subzero weather package....................+ $1,000
Upgraded paint....................................+ $1,000
Upgraded audio..................................+ $2,500
Ludicrous Mode..................................+ $10,000 (Requires Dual motors)
Fully Loaded...................................................$69,500
Fully loaded M3 should be around the base price of S/X.
Note: I'm predicting no air suspension option and no upgraded charger option. Also by the time the 3 is out I expect the X/S to be shipping with only two physical packs, a 100 and a 75/60 with the 100D getting 340 miles range and the 75D getting 260.
