* The following is speculation and supposition...
I too notice that there seem to be fewer Used cars in inventory as compared to a couple months ago and whereas prices seemed to be dropping $1K-$2K per month they seem to have stabilized.
Part of it may be a factor of how many 3-year old lease returns are coming back to Tesla, and how fast they make those available to the Used market.
This chart shows deliveries per quarter. Q4 ‘15 has a bump in deliveries compared to prior and the 2 following quarters. Those would have come back Q3-Q4 2018 and may have generated more Used/CPO inventory in Q1 2019.

Tesla also had a $900+ Million bond payment due in early March ‘19. For cash management they may have directed all lease returns into the Used pool to sell quickly to raise cash. Someone with a history of getting Service loaners might be able to contribute on that. Does anyone know where Tesla sources their service Loaner cars? It would not surprise me if lease return vehicles entered the Service Loaner pool while also being listed for Used sale or while they might be working on Title paperwork. If that was a normal thing, then to raise cash for the bond payment they could have sold all lease returns asap and offered ICE rentals as Service Loaners instead. The cash from sales would far outweigh the cash to rent ICE cars.
Coming up, Q3 and Q4 ‘16 were at that time record delivery quarters. If the deliveries were backloaded in Q3 (Sept) then those Q3&Q4 ‘16 cars will be coming back over the next few months and we might see overall inventory numbers in Used rise a bit.
I imagine EV-cpo could data mine and provide weekly charts as to # of Used/CPO cars available and it might be interesting to see if/how those relate to delivery volume of 3 years prior to see if there’s a correlation but it really is just a question to ponder idly. It comes down ultimately to there being a specific inventory of cars at any given time, at the prices Tesla has set, and whether someone wants to buy at that price at that time.
Very few investory cars are within free delivery area of Mississippi so I’ve more or less set the expectation to myself that I’ll really be purchasing in June-July because I can arrange for a July delivery on the west coast when I’ll be out there anyway. Then I will have a better selection from the greater inventory on the west coast, can avoid Delivery charges, and either drive it back or trailer it behind the Expedition.
