Err... (before tax credits) $57,400... which became $59,900. As for "nobody", well, Tesla claimed 4%, but that was before they really gave it a chance since they started shipping the most expensive units first.
Toyota sold/leased all ~2600 ~40 kWh Rav4 EVs. All the rest of the non-Tesla EVs don't even have 40 kWh capacity. The most popular EV in the world and US only has a 24 kWh battery (well, until the 2016 Leaf SV and SL).
Margins or not, hope you realize that TSLA is still losing money, despite whatever margins they have. As I posted at
Statistical poll of the drive unit issue - Page 7, at the time, Tesla Motors had accumulated ~$1.381 billion in losses.
Two more (money losing) quarters have passed, so if you continue to add those negative profits (see net income figures at
TSLA Income Statement | Tesla Motors, Inc. Stock - Yahoo! Finance for quarters ending Jun 30, 2015 and Sep 30, 2015), their accumulated losses are now up to almost $1.8 billion.
