Before you roll your eyes

Sorry it’s listed as a 66, and didn’t sell until 67 from what I’m seeing

Not unheard of. My '68 GTS convertible (red/black bucket interior/no console/340/column auto) has an SPD of 8/28/67 and, according to the owner's manual a first sale date of May 14, 1969. I've also been looking at new Durangos lately. There are three brand new 2019's listed on Autotrader right now. The mileage written down on the owner's manual in the second pic was from February 1970. Either it had some miles when first sold or Robert drove it a ton in 9 months.
