I know you mean well, but this has been beaten to death. If you're in a position where getting a $35,000 (plus tax, title, registration and delivery) vehicle is a stretch, you also may not even be in an income bracket where you could take the full benefit of the tax credit.
Everyone's situation is different, but telling people the cost of the car is "basically $27,500" is fundamentally flawed.
The tax credit comes at the end of the year, IF you qualify.
And you're not going to be financing or paying sales tax, property tax, or insurance on a $27,500 car.
For some people, the tax credit is a given, and moving the money around is just a matter of getting on your phone and making a few clicks.
For others, it's life-altering to get to that point, and those people shouldn't be overreaching.
