This is definitely an important factor in the model. The frame of mind I tried to use is, what would I pay today, in 2014, for a luxury car of Tesla caliber that is, say, Model Year 2006?

Then I took a few other things into account: - Quantitatively, given the paucity of data on Model S resales (I've looked at this and I think prices are high because supply is low), what does depreciation history on the Roadster imply for the Model S looking forward? - Qualitatively, what is the impact of a battery swap say 8 or 10 years down the line, if the cost of the battery is approximately $12K (based on Tesla's earlier comments and the Roadster battery swap program) or less (if the Gigafactory succeeds)?

What range did your imagined 2006 model have?

I put the info on the depreciation worksheet. I used a range of 11.5-13% per annum based on observed values for the Roadster, and to be conservative, used 13%.
