suspension 530 SE v M sport

[Robmilford]

Hi,I'm looking to buy a 530i touring, 2007 ish model and the advice I have been given has steered me towards the M sport rather than the SE, however I currently own a E46 330 SE and find the ride a bit harsh and was hopeing for more comfort from my next car. The question is what, is the differance in ride comfort between the SE and the Sport.

Cheers Rob
