I don't anticipate needing the complicated lease/financing scheme announced recently, and I think all the voodoo math around hourly savings is hard to defend and unlikely to convince anyone. i am planning on either paying cash or getting conventional financing (don't need the financing for the down payment, etc). However I am interested in Elon's residual value guarantee. I think most of us wonder how well the Model S is going to hold its value, especially with Gen III and other future Tesla developments. I am sure having the piece of mind that, if we are unhappy, Tesla would buy back the car after X years for the same retail value as a Mercedes Benz would get a lot of people to decide to formalize their order. I asked at the Tesla store and was told the guarantee is only if you do the financing. Why? I would even guess that some people would pay an extra $2500 for "guaranteed resale value" or something like that... thoughts?
