You should be aware of how that $7,500 works.
First, it is not a rebate; it is a non-refundable Federal tax credit. That means you must have a Federal tax bill of at least $7,500 in the year you buy the vehicle to take full advantage. If your tax bill is less then that's the tax credit you'll get.
Second, once a manufacturer (not model) hits 200,000 US unit sales of qualifying vehicles the tax credit phases out. In the first six months after a manufacturer hits the 200,000 mark the tax credit is cut in half and then in half again in the following six months, then eliminated entirely after that. For example, $7,500 goes to $3,750 in the six month period after the manufacturer hits 200,000 in sales, then $1,875 for the following six months, then zero.
Third, not all EVs/plug-ins qualify for the full $7,500. It depends on battery size. For example, RAV4 Prime plug-in does currently qualify for the $7,500 whereas the Prius plug-in qualifies for $4,502. I would not venture a guess on when Toyota (or anybody else) will hit 200,000 in US EV/plug-in sales but be aware the clock is ticking. Your "when ready to buy" could have a credit phase out or expiration date.
Fourth, Tesla and GM are the two makers who have burned through all credits. Any EV/plug-in from those two have zero Federal credits.
Fifth, as for a particular state tax credit, you'd have to get into the weeds like these Federal weeds to see if you and a particular vehicle would qualify and for how much.
Here's a recent list of qualifying EVs and the amounts of potential credits:

There is a pending Democratic bill that would extend the program, with a max tax credit of $12.500 up to 400,000 units. Chances of getting this passed? No comment.
