That is not how the tax credit expires. The full credit expires the quarter after the 200k US car has sold.
Yes, thats exactly how the tax credit expires... by date!
There are four quarters per year
Quarter 1 (Q1): January 1 - March 31
Quarter 2 (Q2): April 1 - June 30
Quarter 3 (Q3): July 1 - September 30
Quarter 4 (Q4): October 1 - December 31.
So the key dates for the pissed off guy are Jan 1st, Apr 1st, July 1st, or Oct 1st. If a single day earlier then he'd be in the previous quarter.
Hopefully this makes sense to you now. Reread my post and the "...
takes delivery one day after the full credit expires." part will click for you.
The full credit could expire on a March 31st, June 30th, Sept 30th, or Dec 31st. The half and the quarter credit will do the same on one of those dates.
Basic point is, if you get bumped from one of the expiration dates to the first day on the next quarter then you're screwed.
