In Europe, at least, the used EV market has also cratered. The problem there is that PRESENTLY, companies selling cars in Europe have to make a 22% EV quota on their overall sales (ratcheting up to 100% in 10 years), yet no one wants to buy those cars.
So some numbskull who bought an EV several years ago shows up at a dealer hoping to trade-in his EV to buy another car (gas or EV, doesn’t matter) but the dealer has no use for his EV, as the dealer can hardly find anyone to even buy them new, and yet still has the mandate (for now)...so used prices CRASH.
