[9] The chairman explained to the shareholders' meeting in December 1950 that Singer made no motor vehicles from March 1940 until after the end of the war and for this reason the SM1500 employed and was built using out-dated pre-war technology.

[10] Singer's SM1500 had a pressed-steel body mounted on a separate chassis with at the front a Packard designed coil spring independent suspension built under licence.

The four-speed gearbox had a column change which made it difficult or impossible to select second and reverse.

Singer's engine was based on the one used in the Super 12 but with larger bore and shorter stroke, giving a capacity of 1506 cc.

[3] It was reported that the engine block was so tough that the manufacturers were happy to quote 65,000 miles (105,000 kilometers) as a "normal" interval between rebores.

[11] Inside, the car had a bench front seat with folding armrest and was optionally covered in leather.

[14] The SM1500 as well as spacious and stable was sturdy and reliable but all the controls were too heavy for most women and the steering column gear change defeated many.

[3] A single carb version tested by The Autocar Magazine that same year managed a top speed of only 71 mph (114 km/h), a 0-60 mph (97 km/h) time of 27.9 seconds and an impressive overall fuel consumption figure for the road test of 29 miles per imperial gallon (9.7 L/100 km; 24 mpg‑US).

[13] In September 1954 the car was re-branded as the Singer Hunter with a traditional radiator grille and fibreglass bonnet lid.

[13] The Times motoring correspondent tested the new model and reported in June 1955, under the headline "Reversion to "Traditional" Radiator Shell" followed by "Cushioned Comfort", that this car was intended for the motorists who are prepared to pay for a rather better finish and more complete equipment than usually available in cars of this size.

The car is shown in several rather pointless tracking shots at the beginning of the film, and it may be that this was an early example of product placement.
