Not having owned a G80 but driving one hard and having owned an M2C, I would not recommend an M2C to almost anyone unless it's truly an extra car or track only car. It really sucks as daily driver, limited space, real struggles with grip and the car is kind of all over the place... the M3C does everything better outside of feel - which to many people is a huge component.
