The 1975 Six was the final Wolseley to be built. Designed by Harris Mann, the car that would forever become known as ‘The Wedge’ was the posh version of its Austin and Morris lookalikes, available only with the 2227cc six-cylinder engine (its humbler siblings were also available with four cylinders). At the front was a much shrunken version of the traditional Wolseley grille and light-up badge, the distinctive shape of the car dictating no room for anything larger. After just six months, the entire range was de-badged and the cars just named Princesses.
