instead of $7,500. The income limit is cut in half for both single and joint filers, the price of the used EV must be $25,000 or less, needs to be at least 2 years old, etc. Familiarize yourself with the official IRS guidance here

There's a reason used EVs are relatively inexpensive, it's because you're that much closer to the warranty expiring on the battery and if that fails outside of warranty you're out a substantial amount of money.
I bought a brand new 2023 Tesla Model Y Performance last year. I love everything about the car. Given today's EV prices, and factoring in the tax credit differences, it makes 0 sense to buy used. I plan to sell mine before the 120k mile battery warranty is up.
Have you considered a Model Y over a Model 3? The hatchback and extra room are extremely nice, and Model Y prices are actually cheaper than Model 3 because it hasn't gone through the refresh yet.
