Vauxhall Viva (HA series, 1963 to 1966) model years

The model years of the Vauxhall Viva (HA series, 1963 to 1966), 1963 to 1966. Each model year page in this group states what changed in that year and links back to the generation page, to the Vauxhall Viva model page and to the previous and next model years, so a reader can move through the whole span of the generation one year at a time. Body style is recorded as a property of each page, not as a group, so a generation that was sold as a sedan, a hatchback and a coupe still keeps all of its years together in this one place on the site, and the generation page itself gives the overview of what defined the generation.
