Out of curiosity, how does your model work and how do you reconcile its results with the fact that the all P85 listed as CPO's (including 2013, up to 32Kmiles and no AP) range a lot higher ($70,500 to $79,800)? For example, there is a huge discrepancy between your model price of $48,700 and a comparable VIN and miles CPO at $76,900 listed here: 85 kWh Performance Model S P52014 | Tesla Motors. $28,200 difference cannot be accounted for by options since all the options on the aforementioned car didn't cost $28K brand new. Is your model in USD?
You must have entered a wrong item or omitted something. The model generates a value of $76,647 for that CPO listing.
