I have a new 330i PP SP CWP, and I have to say that while I find the steering to be SLIGHTLY lighter than in a 328i I had tested, the difference is negligible at most. And despite what others may say, a CL Type S is a truck by comparison. As far as an A4, the 330 is SLIGHTLY better on straightaways, but blows away the A4 in the twisties. I won't even compare it with the SLK, my 330i has far superior steering and handling. I've been driving a 330i for 11 days now, and test drove all the other cars mentioned within the past month.
