Is that the averaged "offered" price or the averaged "sold" price? The EV-CPO site shows various discounts from original asking (offered) prices (admittedly, the age and mileage of never-titled vehicles plays a role in the discounting)
Also, there have been various anecdotal claims of negotiating lower-than-offered transactions for vehicles in inventory, particularly in the final weeks of a quarter.
As more EV alternatives come to market, Tesla's "no discounts" policy may come under stress.
The price includes any Tesla discounts already offered including the larger discounts on new inventory cars which have been demo cars. EV-CPO data for this purpose is manipulated by Tesla as it only covers the cars Tesla want you to see. It may be that the figure is skewed by models Tesla is having trouble selling and so appearing for sale, but you’d hope they weren’t making large volumes for stock with an undesirable and expensive config. Tesla may sell for lower still, may offer higher trade in or subsidise lease deals ending, etc too.
