The Humber 9/28 was introduced in 1929 by Humber Limited. This rear wheel drive car was available as a 2-door coupe, 4-door sedan and tourer (convertible). With a manual 3-speed transmission, the 9/28 was powered by a 1.1L inline four engine. This model was popular within drivers looking for a practical and reliable car, backed by Humber's reputation as a quality manufacturer. The Humber 9/28 production ended in 1933.
