I always put BP Ultimate 98 in my car. It's more expensive, but there is a powergain of a few hp and more mpg. As I recall TopGear(?) tested a few fuelbrands with different octane a few years ago, i.e. a Golf GTI engine (200BHP stock) had 195BHP with fuelbrand X(95/91 whatever) and 212 BHP with BP Ultimate 98...if I'm not mistaken.

At the moment when they aren't even delivered yet, it's all PRO 328 and CON 335.
I don't think that will change a lot once the former I6 drivers collect/drive their 4 potters. As we all here already stated, you have to live with the sound. And that is the only CON I can find in a 328i for now.
