I think you would be better off with a straight lease, but to set that up you need to calculate depreciation correctly. In this case it seems like tesla is protected from having to eat it if the depreciation of these vehicles is insanely high. The cost is passed on to the customer. Although tesla will be on the line for the difference between the Model S and the S-class should the Model S depreciate faster.

The other thing is that I thought they couldn't make these fast enough as is? Why do they need a financing product like this to get people into the cars?
