The Riley Nine was one of the most successful light cars produced by the British motor industry in the inter war period. It was made by the Riley company of Coventry, England with a wide range of body styles between 1926 and 1938. The car was largely designed by two of the Riley brothers, Percy and Stanley. Stanley was responsible for the chassis, suspension and body and the older Percy designed the engine. The Riley company was bought by Lord Nuffield in 1938 and nine production ceased as the company pursued a strict 2 engine line up, continued after the war with the RM series.
