My car runs fine but has made me a bit paranoid.
If it's running fine, I wouldn't be too worried about it. Now if the car refuses to start the first time (and maybe throws a code), that's when I'd start investigating. Probably ICV, but I wouldn't worry about it too much yet. The M3 just likes to be driven
