Hillman Minx touring car, 1932. The Hillman Motor Car Company was founded in 1907 but by 1929 Hillman had just become a marque, being bought by Humber which was in turn bought by the Rootes Group in 1931. This is probably one of the earliest examples of the well-known Hillman Minx cars made by the Rootes Group. The ‘Minx’ cars were made between 1932 and 1970 and included many variations including saloons, estates and convertibles; however the first models were touring or, like this one, touring-sports cars. The Hillman name is now owned by the French company Peugeot.
