I got an M3 and to be honest its perfect, its the car the 3dr was when I got 10 years ago. i.e I can just use it without worrying about the value of the car/getting parts. I'll probably get another 3dr and kick the m3 out onto the drive at some point but the sierra will be something nice to have in the garage while the M3 is something I can just jump in and kick the arse out of in any weather or not worry about someone hitting it etc. Cossies are a bit too precious for that I feel.
