What This Means If You Are Selling an EV
Tight supply and rising sales velocity mean serious buyers are competing for a limited pool of used EVs. That is the definition of a seller's window — and windows close: lease returns and fleet de-fleeting add supply in waves, and each wave softens pricing. Sellers who move while supply is short capture the premium.

What This Means If You Are Buying
At 42.8 days of supply, desirable used EVs are moving fast — well-priced examples of popular models rarely sit. Buyers with financing arranged in advance have the edge, and pre-owned continues to be where the value is: new-EV supply remains far looser than used, which tells you where demand actually lives.
