The Austin A135 Princess Mk III was a refined and prestigious luxury saloon and limousine produced by Austin in the mid-1950s. Building upon the success of its predecessors, the Mk III introduced subtle design and mechanical improvements that enhanced its appeal to both private buyers and official fleets.

Under the bonnet, the A135 Princess Mk III retained the reliable 4.0-liter inline-six engine, delivering smooth and effortless performance. The car featured a four-speed manual gearbox, with some versions offering an optional automatic transmission for greater convenience. The robust chassis and advanced suspension system provided a comfortable and stable ride, making it well-suited for long-distance travel.

The exterior styling remained elegant and stately, with a prominent upright grille, sweeping fenders, and refined chrome detailing. The interior was crafted with luxurious materials, including high-quality leather, polished wood trim, and thick carpeting, creating an opulent environment for passengers. Limousine variants featured a partition window, additional seating options, and increased rear legroom, catering to chauffeur-driven clientele.

The A135 Princess Mk III solidified Austin’s reputation for producing distinguished luxury vehicles. It was frequently used for official purposes, including state functions and diplomatic transport, further emphasizing its status. Eventually, the model evolved into the Vanden Plas Princess series, continuing the legacy of British craftsmanship and automotive excellence.
