I had a first gen 350z that had horribly calibrated rear springs which made the rear end literally porpoise up and down on uneven pavement or road expansion joints. Many owners at the time were going to full aftermarket air suspension set-ups to get rid of it since none of the 3rd party guys had figured out how to dial out the bounce in their own springs yet without sacrificing ride quality.
Air suspension handles night and day from spring/shock set-ups. It doesn't continue bouncing/rebound after hitting a bump like springs do.
Granted BMWs are so dialed there's probably not that much difference in the ride, but here in Northern Cal with our crappy freeways, ill take the chance!
