Let me put an end to all of this right now. I own an IS and a 2001 Z3 3.0 (automatic). I also had a 2000 Z3. Without a doubt, the Z3 romps on the IS. No comparison. The IS is sporty and moves, but driving the 3.0, you actually feel like you have power. You feel the car rumble when you get on it.
No comparison whatsoever.
