Last week, someone on Facebook was asking people if they would cancel their Model Y order if they couldn't get the $7,500 tax credit. After I said that I would, someone else accused me of being $7,500 away from financial ruin.
I smiled, then excused their criticism since they knew nothing about my financial situation and explained that I owned my home and automobiles outright and had zero debt. That is possible
because of self-imposed limitations like choosing to $45,490 instead of $52,990 for a Model Y. I
could pay full price for a Model X, but I
choose not to - I can't bring myself to pay as much for a depreciating asset as I did for a new home 11 years ago.
Let's be honest, though - it's nearly impossible to justify any Tesla as a "responsible financial decision". The most responsible financial decision would be to take public transportation. If that's not available in your area, then buying a used Prius would be about the the most responsible solution for personal transportation.
If you're going to buy an EV, about the best financial decision would be a new Chevrolet Bolt which can be had for less than $20K after the tax credit right now or a used Nissan Leaf, but of course, those aren't as unnecessarily nice or exciting as a Tesla.
