I was hoping you guys could tell me how the trade in program at Tesla Motors works. I own a standard 85kwh Model S and was thinking about trading it in for a P85D, however I want to lease the P85D. It seems straight forward but I've never traded a car in so I'm not sure how the process works. Another question: Is there a way to know if I qualify for the lease before trading my car in and before placing the deposit, I just don't want to lose the deposit in case I don't qualify I am thinking about an inventory vehicle I found on the website, not a custom order. Thank you! and Merry Christmas!
