Just as an additional data point, I got a lease termination quote from Tesla. They listed the market value of the Model 3 at $45k and a lease payoff of just over $50k with me owing the difference. I went to Carvana and requested a quote to buy the Model 3 and they offered me $54k, so I think that as soon as I take delivery of my Model S I will just go ahead and sell my Model 3 to Carvana, Vroom, CarMax, etc. (whichever offers the most). Seems like I might even walk away with a few dollars going that route vs paying Tesla over $5k to terminate the lease.
