According the the BON, the last MKI was made about
Aug 6, 1965. The improved B382’s (MK Ia’s) began
production shortly after in 1965 and continued thru
December 1966. the B38210001 MK II was made
in December 1966 and the rest in the 1967.
Most Tigers were shipped close to the production
date. The applicable Federal laws applied to the date
it was made not thhe model year. Each state has its
own laws as to what year to title a car. A MK IA made
in 1965 could have been sold as a 1965 or 1966
depending on the state. Just like today, a Ford made
the Fall could be sold as a 2005 or 2006 depending
your state. I saw an leftover MKIA sold as a 1968
Tiger in WI.
Whatever year, enjoy the car.
