Picked up a E320 today (non-4Matic) that has a couple features I just don't recall being in my former E320 (4Matic) (bought new in '02). This one has Parktronic, & instrument cluster illumination, & trip reset buttons that I just don't recall being in my old E320. Were there mid-year changes in '02? Or were these features there all along & I'm just having a senior moment? Thanks.
