1. You can drive in the efficient relaxed mode very comfortably. No worries about driving it a ton, very smooth
2. No worries. It's comfortable but can be agressive when you want it. Perfect balance
3. None that haven't been addressed. Oil pump was a problem but they have fixed all cars.
Buy it, you will not regret it. Best car I have ever owned.
Edit: some drivers experience a clunk in the rear suspension, most don't have the issue. I don't. Not sure what BMW is doing abut it, if anything.
