Announced in October 1961,[5][6] the Super Minx gave Rootes, and particularly its Hillman marque, an expanded presence in the upper reaches of the family car market.

[6] The convertible never sold in significant numbers: the last one was made in June 1964,[2] ahead of the introduction, in September 1964, of the Super Minx Mark III.

A year after the car was launched a Mark II version was presented, in October 1962, with greasing points eliminated, larger front disc brakes and a revised axle ratio.

Engine capacity was increased to 1,725 cc (105.3 cu in) for the Super Minx Mark IV launched at the London Motor Show in October 1965.

The test car was priced by Rootes in the UK at £911 including taxes, at a time when the Austin 1800 was retailing for £888 and the Ford Corsair GT was offered at £925.

The performance was felt to be lively, and the gear change, supported on the test car with an optional overdrive, ‘crisp’ with well chosen ratios.

Comfort and fittings were also commended, but the fuel consumption and the tendency of the heavy brakes to fade when used hard disappointed the testers: this would presumably not have been an issue had the road test been of a Humber Sceptre which had its stopping power from a servo-assisted 10-inch (250 mm) front disc/rear drum arrangement.

The later H120's 107 hp (80 kW) engine is a straight swap for both of these units and looks almost identical - it provides a useful boost in power to an already swift automobile.

The unique Sceptre interior featured full instrumentation, including a tachometer marked up to 6,000 rpm, and a four-speed floor-mounted transmission with self-cancelling overdrive (with column-mounted control and indicator) on third and fourth gear for a total of six separate ratios in standard form.

This was a cheaper option than was usual at the time due to the deletion of the Laycock De Normanville overdrive fitted to the Manual cars.

However, the Hunter was initially offered only as a saloon and accordingly the Super Minx estate car remained in production until April 1967.
