Nice cars - very solid and far more refined than a ZS. Not as fast - even less frugal if you stick with a V6.
A V6 160 has taller gearing so is a more relaxed cruiser. 1.8T 160 probably a decent mix of speed and economy. 135 diesel is a BMW unit is well thought of and also very tuneable.
Stop messing and just buy mine ....
