I wrote this on bimmerpost, here is my thoughts, maybe it will help some of you:
Base price ( manual) will be around R750 000 (my opinion), give or take R30 000. There is no way bmw is gonna price themselves out of the segment, audi rs3 (4.3 sec 0-100km) base price R710 000 and Cla 45 amg which is getting more power as of jan 16 (4.2 sec 0-100) is R720 000.
I also read a article that said it was expected to be between 700-750k.
Also if you use the m235i coupe as a price projection tool. In SA base price is R560 000, in america price is 44 150 us dollars x 14.33= R632 669-50. So at our current exchange rate america seems to be a little higher regarding pricing.
Now it is rumoured that M2 pricing in a america will start at between 51 000-54 000 us dollars, converted that R730 830-00 - R773 820
i am aware this is not a perfect model but i think it does point us the right direction.
Also consider that those prices for the rs3 and cla45 are with dct, so to say that the the m2 will come in at manual around those prices is not a crazy assumption.
