This is a model of an Edwardian-style limousine, similar to the Rolls-Royce Silver Ghost. It is finished in grey/sliver paint with black upholstery and hood. The boiler forms the 'bonnet' of the car with the sight-glass for checking the water level being the 'radiator grille'. The oscillating-cylinder engine is mounted externally on the left-hand side of the model, driving a small solid flywheel mounted externally on the right-hand side via a shaft. This shaft drives the rear axle by a power band. This arrangement provides much higher gearing than the traction engine-based models, allowing a higher top speed. This chassis and layout is used on all the other Mamod road vehicle models. The wheels on the Limo are in the style of wooden carriage wheels (as found on cars of the period) with pneumatic tyres. Details such as mudguards and carriage lamps are fitted.
The Limo is also available in a different colour scheme, with maroon bodywork and brass/gold wheels. This is designated the SA1B.
