Earlier this year, used Teslas were selling for upwards of $10k over what Tesla sold them for new, and Tesla kept bumping up the MSRP. It was the worst used/new value ratio across the industry, probably since there are no dealers you could pay a market adjustment to in order to get a new one immediately instead of waiting half a year.

Now that the delivery time for new Teslas is down to a month or two depending on model, of course used prices are dropping like a rock.
