Getting a barebones vehicle or only having the budget for a barebones vehicle doesn't automatically correlate to not making enough money to be able to qualify for the full tax credit. They may have other expenses or spending priorities, or simply don't care for spending the money on all the options and would be fine with just the base Model 3 (some people on this forum have stated as much).
That is true. I just want to make sure people don't get the wrong idea about how the tax credit actually works.
