I've owned two Z4M Roadsters prior to my current M4, and pretty much agree with Hack that the Z4M platform is outstanding. I love my M4 to death don't get me wrong, but knowing what I know now I likely would have stayed with the Z4M. My biggest problems with my last Z4M were it was 11 years old, had 83k miles on it, and the cars are notorious for both VANOS and rod bearing issues. I looked into the cost of replacing both, as well as the cost to repair the car if either broke, and it just didn't make sense to me from a financial stand point to keep the car in comparison to getting something newer w/warranty etc.
With that being said, if BMW created the Z4M again (built them today without changing a thing), I'd be first in line to buy one. Roadster or Coupe form, I think they're one of the most unsung and underappreciated vehicles of all time.
Ahh, I do miss her though....
