I read on the website :
The final version of the Viva was the HC, and was launched in October 1970. It was to remain in production for 9 years with 640,863 cars being produced at Vauxhall’s Luton and Elsemere Port plants.
7th Digit E = Factory where made E = Ellesmore Port, V = Luton.
I'm pretty sure mine is build in Antwerp (engine bay has an inscription saying so.), but I can't find any info how many Viva's are build in Antwerp.
Is this info available here?
