Per IEVS, Toyota sold/leased 269 Mirais in the U.S. in December, for a total of 1,835 for the year. This total doesn't agree with last month's, as at that time IEVS claimed 1,542 YTD, + 269 = 1,811. Perhaps they updated the old number.

The 'best' is the enemy of 'good enough'. Copper shot, not Silver bullets.
