I have an early '15 P85DL with the stiff suspension and vin 73k. Love it. Call me crazy, but I'm not sure I would trade it at even money for a new P100D. In my very personal opinion, the P85D's advantages are 1) the stiff suspension (where you should test drive and make your own judgment); 2) the old nose, which is sleeker and better looking, in my opinion; 3) AP1, which is in a better state than AP2 right now; 4) a leather interior, not leatherette; 5) the yacht floor, which I prefer over a console; 6) slightly higher current dual chargers; and 7) HID headlights, which I have heard are brighter than the current LED, although I have no personal experience here. Obviously the P100D is quicker, but the P85DL's 0 - 60 in 2.9s seems "adequate", and any maneuver that I could accomplish in a P100D but not a P85DL would probably kill me.
