Common cosmetic/electronic aging items: the grey dash trim panel discolors (a couple hundred dollars to replace), the driver's seat leather cracks on most NCs (early tan interiors also suffered uneven color shift), and the factory Bose head unit/amp is a recurring failure — owners either swap the head unit or do a full 'Bosectomy.'
