Looking at very low mileage 2019 Teslas for sale on Autotrader, in the $40-50K range is about right. The cheapest used 2019 model 3 in the whole US is more than $33K. And the only 2020 examples are much more expensive.

You can argue forever about technicalities, but $33K is not an apples-to-apples comparison. In fact, I would say if you are comparing brand new 2020 cars, $50K+ for the model 3 is more realistic, and you should take into account the discounts other cars have.
