1975 Vauxhall Cavalier Mk1

The Cavalier proved to be a major turning point for Vauxhall – the Opel Ascona-based saloon proved the perfect weapon for the Luton manufacturer to go Cortina fighting.

Luton built cars were more prone to corrosion than their Belgian counterparts, but all were leagues ahead of earlier models – even if it was at the expense of their ‘Britishness’
