I would have only gotten a little over 1k of the rebate based on this years taxes, the Model 3 is quickly becoming too expensive.
The tax credit isn't free money, you have to have earned enough to cause you to owe at least that much in tax. (So you have actually earned the whole $7,500 if you get it.)
I might agree that if someone doesn't qualify for much of the tax credit that the car is likely too expensive for them. (But not always, there are cases where that wouldn't be the case.)
