OP: you have a bit of a mix of mis-information and assumption In your post so thought below would help:
A) Wait out for the next batch of P3D- (I understand they were produced in 2018)
There were a small number made in 2018 ; but any you have seen for sale the past couple of months have definitely been made in 2019 (possibly all made in July of 2019).
Just missed my opportunity to grab a P3D-:
I would not assume that ; NO ONE knows if they are producing more currently, will produce more this month, next month. The information told by sales agents that work for Tesla is often proven wrong on this board. There do seem to still be inventory around the US ; maybe just none in your region and the reps don't want to look at other region availability.
Do not believe anyone who tells you they know what Telsa will do with the model 3 next month unless you are talking to Elon himself. They have proven to be a total wild card. Even Musk seems as unpredictable as Trump ; No one knew the P3D- was coming, no one knew the Multi-Pearl White was going to be a free option, or knew about the prices decreases until the day they happened.
You can always order a regular Performance model, 2019. If you want the rims, brakes, spoiler, etc... that model just decreased in price significantly and is definitely available to be built / ordered.
2020 won't be available until 2020. Prices likely will be lower then but you will not be able to get any Federal Tax credit on a 2020 model.
Thanks for taking the time to the reply. I should have been more clear with the first option. It does read like I thought the p3d- available now were built in 2018. I just meant there was another batch in 2018. I'll make the edit for anyone reading in the future.
Tesla does seem unpredictable and I tried to squeeze some info from a friend who works in Tesla(not sales). You are right no one but Elon truly knows what's coming.
Anyway, I thought 65k for performance was a bit much vs competition. 55k is reasonable but 49k would be amazing. I ended up ordering a 2019 P3D. Life is short as others have said . Plus I don’t want to wait for my bmw M3 warranty to be expired when selling.
