Hello. I just ordered my Model S and chose to lease it for two years. I will trade in my Prius for it. If I lease, I loose $10K for the total cost of the car. Cost to own is 69,742 @ 824 per month. With lease, cost to own is 79,543 @ 343 per month. Maybe the loss will be less if I buy the vehicle in two years? If I decide to get a new Tesla in two years and turn in this one, will I get a new one with no out of pocket expense? I was only able to afford the lease because of trade in. What happens to all the money that I put in from the trade in? Thanks! Phillip.
