 While this is certainly the finest car I've ever owned, I have been rather disappointed with a few items.  Good stuff: This car has an amazing balance of handling prowess and ride quality.  It's quiet (except for Dunlops) and feels planted at any speed.  The sport seats are incredibly supportive and the controls are well-placed.  Silver/black which is a stunning combination.  No comparison to my Saab 9-5 in most ways. Main complaint comes from the seriously weak sound system (base system) and the creaks/rattles that come (I'm told) from my fold down seats.  Hey BMW, don't offer fold downs if you can't build them without resulting in rattles.  Rust spots not covered by BMW (still fighting).
