Hate to tell you my friend but it's your math that is totally wrong.
It's not of course.
You just added a bunch of additional items that weren't involved (like FSD- which BTW EAP alone, at 5k, gets you
every single thing the $7000 FSD does as of today)... then you added sales tax based on...wherever you live I guess despite the fact your tax rate being insanely high compared to most people.
Then you also added paint/interior which I specifically said could represent an actual difference but only depending on which ones you picked so again NOT for everyone
For example a black interior black exterior is cheaper now. $0 for both things.
Not to mention I also specifically said "a P ordered today"
Which means your tax credit is $0.00 because it won't be delivered until after Dec 31.
And of course the $5000 refund counts. You don't get to exclude it because you personally thought it impolite to take free money.
And you ignored the extra HW '18 buyers get that 20 buyers do not.
So here's the "real" math for you if you wanna play let's cherry pick colors and whatnot-and I'll even toss in FSD to help you out.
2018-
$69,000 for P3D+
Black interior and exterior- $0.00
FSD (with EAP) $8000
Destination- $1200 (though if you really want nit pick- it was actually $1000 for most of 2018- got raised in the fall)
Oh, and I'm buying this car Delaware. No sales tax.
Total of- $78,200.
Then I take a $7500 tax credit, and a $5000 FUSC refund.
NET COST 2018 P3D+ black/black with FSD in Delaware= $65,700.
2020-
$56,990 for P3D+
Black interior and exterior- $1000
FSD- $7000
Destination- $1200
Sales tax still $0
Total of- $66,190.
Huh. The 2018 car is $490 cheaper...and we aren't even done yet
The 2019 car also needs about $500 more to add homelink, the 14-50 adapter, the mats, and the phone cables that the 2018 all came with for free.
So about $540 more expensive for the 2020 car.
If I wanted to cherry pick even more I'd knock off $200 destination by buying in late June 2018... and another $120
every single year because I got lifetime connectivity that way... and if we wanna play "functional equivalent" I can take the 3k of FSD off since EAP does the same stuff as of right this moment.
Hopefully you can understand why I stuck with "just the car" instead of getting into the weeds of color pricing and if your state has an insane sales tax or not.
And why the whining about I PAID 20k MORE is utter nonsense.
Even taking the worse case as you did if you were honest and counted the 5k refund and the equipment difference you'd barely crack a 5k difference... and just changing a few of those options totally evaporates that difference to the point it's cheaper to have bought the 2018.
and that's without adding up a year of savings not buying gasoline too.
Thus endeth yet another math lesson
