In reading the document attached to Elon's tweet about Tesla Model S being the highest residual value car over a 3-year period - see link - I noticed this important quote about the Federal Tax Incentive:
"The federal credit begins to phase out for vehicles at the beginning of the second calendar quarter after the manufacturer produces 200,000 eligible plug-in electric vehicles (i.e., plug-in hybrids and EVs) as counted from January 1, 2010."
If this is the case, with production ramping up on Model S and over 55,000 already produced, Model X production coming on line in Q3/Q4 2015, plus any Roadsters built between 2010 and the car's production end, aren't we soon approaching reaching this 200,000 vehicle threshold? Won't it be reached in 2016?
Here's a link to the full report:
With Republican majorities in the House and Senate, I don't see them extending the Federal Tax incentives any time soon.
