Standard bodies were a four-door sports saloon from coachbuilders Charlesworth, a four-seater sports coupé or four-door tourer by Cross & Ellis, but some cars were supplied in chassis form and carried bodies by coachbuilders such as Vanden Plas.

It used a single plate clutch, central change lever, open tubular propeller shaft with metal joints (arranged in a straight line), and a spiral bevel fully floating back axle.

The SB launched at the October 1933 London Motor Show had a new cruciform braced chassis, slightly longer at 124 in (3,150 mm), with independent front suspension using a single transverse leaf spring with a long solid anchorage in the centre.

[5] The Times motoring correspondent tested and after describing its technical features in detail reviewed the car.

The four-seater saloon was described as "distinctly fast in acceleration and speed" with a comfortable body such that a passer-by looks twice at it.

Providing on the road such rapid acceleration and high rates the engine ran fairly quietly and with smoothness yet displaying exuberant spirits.

[3] The final SD version for 1936 was similar to the SC but had a larger fuel tank and slightly wider bodywork.
