I am thinking about putting a deposit down for the Model 3. The new delivery updates state that a new reservation today for a LR battery and RWD will be delivered in 4-6 mo. And the LR w/ AWD would be 6-9 mo. I would prefer AWD but would much rather have the $7500 tax credit. It seems like for a new reservation there is almost no chance for a LR w/ AWD to be delivered before the full tax credit expires(I'm assuming 12/31/2018). So am I reading it correctly that if I place my reservation today for a LR w/ RWD I should receive delivery before 12/31/2018(and get the full $7500 tax credit)? Also, does this version require the Premium pkg? Thanks.
