In 6 days, in the US, EV prices will shoot up by as much as $7500 thanks to changes in policy and incentives. Used EVs and hybrid vehicles will also see a price hike.
So if you're considering an EV, the next 5 days is when to jump on it.
From my understanding, the transaction just has to start in the next 5 days. You don't need to take delivery in the next 5 days.
