I always wanted an Auto Union. My favourite Dinky Toy was an Auto Union record car. I can still feel its fins and spats with a five-year-old’s fingers. Dinky only made it from 1936 to 1940. This is a later one rebuilt and shown at Geneva in 2009. It was in my teens, as what Laurence Pomeroy liked to call a student of motor racing, that I realised how important 1930s Auto Unions had been.
