Also, the 40 KWh ("160 mile") version--that is, the ~$50k version--was not actually available within the first batch of manufactured cars. It may be available now; I'm not sure. During the first few months, reservation holders who planned to purchase a 40 KWh car were told they would need to wait longer. That situation would drive the average selling price upward. Once the manufacture of the 40 KWh cars starts (and perhaps it has already started), and once the relatively wealthy early adopters have purchased their well-equipped models, the average selling price should trend downward. On day one of iPhone 6 availability, are more 64 GB or 32 GB models going to be sold? 64 GB obviously. Microsoft was correctly criticized for not understanding that most Surface Pro early adopters wanted the 128 GB model. Similarly, if you see a Model S on the road today (and I've seen about 15 so far here in Los Angeles) odds are very good it will be a Performance-spec car. Around 10 of the 15 I've seen have been Performance. And when the Mercedes W212 E-Class hit the streets, if I recall correctly the very first one I saw in the wild was an E63. Early adopters buy top-of-the-line.
