Def. get the cameras. I only got the rear PDC thinking the rest of the cameras were for people that can't drive but after picking up my F10 this car is HUGE to squeeze into parking spots and tight driveways. I can see how the cameras could help big time
Another thing well worth is the Nappa Leather. It turns the interior into 7 series level in look and feel.
I have the soft close doors and they are only useful if you have a baby in the car that you don't want to wake up (i do) Otherwise not really worth it imo.
