They listed similar "market adjustments" when the i3 was new to market - I would find another dealer. It seems that a few owners have had good luck with BMW of SF, but for the most part the advice is that there are better options in the area.
The dealer can sell the car at any price it feels the market will bear. Search around, many are discounting them. It might make some uninformed people think they're getting a big deal if it was marked up, then they end up paying full sticker for it!
