Does anyone know how much Tesla tends to mark up CPOs? I'm trying to figure out (roughly) what the trade-in value value of a new car purchased today might be in 2-3 years. Given how sales tax on vehicle purchases works in Washington State, I'm almost certain to trade it in to Tesla. Another vector to consider: how does a lease residual relate to trade in value? 3 year leases seem to be running at 59% residuals.
