Biased group here for sure (including me, but like most I knew the M2CS was coming before I purchased the M2C).
That said:
- Mostly a daily driver? I cannot see an advantage to the CS.
- Track rat? Consider the CS.
- Price? Consider $80K before dealer markup....
- If you are truly going to replace the hood and roof of your M2C with CF parts, the CS might make sense at MSRP (good luck).
- Attention: I prefer a q-ship for my DD, and the M2C is already borderline in that area. I don't want front spoilers, larger rear spoilers, etc.
The M2C remains a great value for the performance. We'll see how the M2CS stacks up.
