Well, as the reviews come in, they appear to be largely consistent. For most who want a fun DD (and especially if you don't care about cosmetic bits or want a semi-sleeper), the M2C fits the bill. For those who want to ultimate M2, who don't care that it looks more extroverted, and perhaps those who plan to do significant track work, the M2CS might be worth it.
And as had been said many times before, if someone with an M2C really wanted to replicate the M2CS, it would cost more money, and (depending on the engine tune chosen) may not have a warranty.
Although I'm not in the market for this car, I am very happy M is building it, especially with a MT option.
