In a quandary as plan either to buy the new W213 (non AMG) or current pre-owned W212 E63 at some stage this year. Need to understand the options on the E63. Appreciate they come well specified as standard but trying to establish if they came with PP/PPP and LSD and/or other "must have" options AND how to establish without a test drive or paperwork. I have not driven one - as may do something stupid like buy it. Finally, did the facelifted (W212) E63 come with the 6.2 or are they all 5.5l?
