Wow, for US a good deal. In Germany from 60D to 75D it is 9700 Euro incl. 19% tax, so somewhat comparable to US, but from 90D to 100D it is 7000 Euro which is more than twice than for US. But still a good deal, especially when considering that the real usable difference between the 60 and 75 is around 10kWh (62 vs 72kWh usable capacity) and between 90D and 100D more around 13 kWh (83 vs 96 kWh).
