With its standout bulbous design, the Morris Oxford Series II replaced the Oxford MO in 1954. Apart from the continuation of the model name, there was almost no carryover from the MO, both in terms of technical aspects or exterior and interior design.
The Morris Oxford, Series II car, had a completely new format while its running gear, based around a 1489cc engine generating 50 bhp, four-speed gearbox and hypoid-bevel rear axle were all drawn from the new B-Series parts bin.
The interior style of the Morris Oxford Series II was such that the fascia was situated quite a distance ahead of the bench front seat, while the steering column and steering wheel were considerably offset.
As well as a four-door saloon, a "woody" estate car marketed as the Traveller was also available.
In 1956 the Morris Minor II was given a minor facelift, after which it was re-launched in early 1957 at the Earls Court Show, alongside its poor relation, the Isis Series II.
Panelwork changes consisting of a new bonnet top with scooped out flutes on each side, and re-designed rear wings were revealed which now gave the vehicle a mildly finned effect.
The Oxford now featured hooded headlamp rims, although these were not included on the Isis, although the Isis now proudly sported a mesh backing to the grille, which quickly distinguished it from the Oxford especially when the car was viewed head-on.
Improved interior finish included glove boxes on each side of a restyled instrument panel and re-positioned switchgear which could now be more easily reached by the driver.
A full-width padded facia top and a deeply-dished safety steering wheel were also introduced.
In answer to complaints received on the mark II version, the Mark III was fitted with a completely re-designed steering column gearchange that gave rather more accurate gear selection than the previous version, and so largely overcame the criticism levelled at the earlier models in this respect.
