WHY IS MY TRUCK TITLED AS A '73?

[OLEYELLERTRUCK]

I HAVE A 72 F-100, WHICH WAS A ONE OWNER TRADE IN AT THE USED CAR LOT I USED TO WORK AT. WHEN IT CAME IN I BOUGHT IT RIGHT AWAY. (THIS IS THE ONE THAT STARTED MY SICKNESS!). WHEN I SAT DOWN TO SIGN THE PAPERS, EVERYTHING SAID 1973. WE VERIFIED THE VIN AND EVERYTHING MATCHED UP. PRODUCTION DATE AND SEQUENCE NUMBER ALL POINT TO 72. ANY IDEAS ANYONE? ALSO LEARNED THE OTHER DAY THAT THE LOWER COLOR PAINT CODE IS A 73 CODE.
I LISTED THE DOOR TAG BELOW. HOPE SOMEONE CAN HELP.

Very, very late model 1972, not sold till 1973? So title reflects sale date not manufacture date. Heard of this on other brand trucks, depending upon state.

in arizona my title says first registered 12/69 but the year says 70. does your title show a dated when it was first registered? maybe your truck was not sold or first registed until 73 and somone goofed on the papper work.

Probably a goof. I have a '66 mustang titled as a '65. No big deal.
