Austin

The Austin A90 Six Westminster was introduced at the 1954 London Motor Show as the successor to the A70 Hereford. It was a big, six-cylinder saloon of which badge-engineered versions were sold using the premium Wolseley and Vanden Plas marques. The steering column gear lever allowed three people to sit in the front.

In May 1956, a derivative of the A90 Six Westminster was announced which was a short boot version of the A105 (the Westminster name was dropped). In October 1956 the A105 received the longer wheelbase with overdrive as standard and automatic transmission as an option. Two tone paint and white wall tyres were introduced for visual effect. The A90 was updated for autumn 1956 as the A95. Along with more power, the A95 was longer and now also offered a Countryman version. Overdrive and automatic transmission were new as well, something of a novelty in British cars of the time.

In 1959 the Pininfarina designed A99 Westminster was introduced, replacing the A95 and A105. After the compact A40 and mid-sized Cambridge, this was the third line of Pininfarina styled cars in a couple of months. Badge-engineered versions were the Vanden Plas Princess 3-litre and Wolseley 6/99. Under the bonnet was the 2,912cc straight-6 engine from the Austin-Healey 3000. 

1959

The final major update arrived in 1961 with the A110 Westminster. This version had an extended  wheelbase, which allowed for more space in the rear compartment as well as improving roadholding. In May 1964 the Mk II was introduced. Most notable differences with its predecessor were the new four-speed gearbox, a modified dashboard and a new grille. Production ended in 1968 when the A110 Westminster was replaced by the Austin 3-litre.
