Thanks to @70 Sport Suburban and @Boydsdodge for telling me about CE27N0C204738. She is currently for sale on FB in Kawartha Lakes, ON. The ask is CAD 6,000. Yes, you read that right: that is only about $4.5k, the car is one of only 11 known Newport N-code 'verts, and she has several interesting options.
From the ad: "1970 Chrysler Newport convertible, 383HP and 727 automatic, is a factory dual exhaust and 4 barrel car. 69,203 miles on car. Newer 2 1/2” TTI exhaust, electronic ignition, rebuilt carb. Painted yellow by a previous owner, originally gold. Has some plastic in it but shows well. Needs a new top. As is. $6000 cash or bank draft. Listed as a New Yorker sedan, no option for Newport convertible."
